### constructor:ArrayType(int,javax.management.openmbean.OpenType) [NONE]
- ### ArrayType public ArrayType (int dimension, OpenType<?> elementType) throws OpenDataException Constructs an `ArrayType` instance describing open data values which are arrays with dimension dimension of elements whose open type is elementType. When invoked on an `ArrayType` instance, the `getClassName` method returns the class name of the array instances it describes (following the rules defined by the `getName` method of `java.lang.Class`), not the class name of the array elements (which is returned by a call to `getElementOpenType().getClassName()`). The internal field corresponding to the type name of this `ArrayType` instance is also set to the class name of the array instances it describes. In other words, the methods `getClassName` and `getTypeName` return the same string value. The internal field corresponding to the description of this `ArrayType` instance is set to a string value which follows the following template: if non-primitive array: `<dimension>-dimension array of <element_class_name>` if primitive array: `<dimension>-dimension array of <primitive_type_of_the_element_class_name>` As an example, the following piece of code:
                                                                                                                          ArrayType<String[][][]> t = new ArrayType<String[][][]>(3, SimpleType.STRING);
      System.out.println("array class name       = " + t.getClassName());
      System.out.println("element class name     = " + t.getElementOpenType().getClassName());
      System.out.println("array type name        = " + t.getTypeName());
      System.out.println("array type description = " + t.getDescription());
  would produce the following output:
                                                                                                                          array class name       = [[[Ljava.lang.String;
      element class name     = java.lang.String
      array type name        = [[[Ljava.lang.String;
      array type description = 3-dimension array of java.lang.String
  And the following piece of code which is equivalent to the one listed above would also produce the same output:
                                                                                                                          ArrayType<String[]> t1 = new ArrayType<String[]>(1, SimpleType.STRING);
      ArrayType<String[][]> t2 = new ArrayType<String[][]>(1, t1);
      ArrayType<String[][][]> t3 = new ArrayType<String[][][]>(1, t2);
      System.out.println("array class name       = " + t3.getClassName());
      System.out.println("element class name     = " + t3.getElementOpenType().getClassName());
      System.out.println("array type name        = " + t3.getTypeName());
      System.out.println("array type description = " + t3.getDescription());
Parameters: `dimension` - the dimension of arrays described by this `ArrayType` instance; must be greater than or equal to 1. `elementType` - the open type of element values contained in the arrays described by this `ArrayType` instance; must be an instance of either `SimpleType`, `CompositeType`, `TabularType` or another `ArrayType` with a `SimpleType`, `CompositeType` or `TabularType` as its `elementType`. Throws: `IllegalArgumentException` - if `dimension` is not a positive integer. `OpenDataException` - if elementType's className is not one of the allowed Java class names for open data.

### constructor:ArrayType(javax.management.openmbean.SimpleType,boolean) [NONE]
### ArrayType public ArrayType (SimpleType<?> elementType, boolean primitiveArray) throws OpenDataException Constructs a unidimensional `ArrayType` instance for the supplied `SimpleType`. This constructor supports the creation of arrays of primitive types when `primitiveArray` is `true`. For primitive arrays the `getElementOpenType()` method returns the `SimpleType` corresponding to the wrapper type of the primitive type of the array. When invoked on an `ArrayType` instance, the `getClassName` method returns the class name of the array instances it describes (following the rules defined by the `getName` method of `java.lang.Class`), not the class name of the array elements (which is returned by a call to `getElementOpenType().getClassName()`). The internal field corresponding to the type name of this `ArrayType` instance is also set to the class name of the array instances it describes. In other words, the methods `getClassName` and `getTypeName` return the same string value. The internal field corresponding to the description of this `ArrayType` instance is set to a string value which follows the following template: if non-primitive array: `1-dimension array of <element_class_name>` if primitive array: `1-dimension array of <primitive_type_of_the_element_class_name>` As an example, the following piece of code:
                                                                                                                    ArrayType<int[]> t = new ArrayType<int[]>(SimpleType.INTEGER, true);
    System.out.println("array class name       = " + t.getClassName());
    System.out.println("element class name     = " + t.getElementOpenType().getClassName());
    System.out.println("array type name        = " + t.getTypeName());
    System.out.println("array type description = " + t.getDescription());
would produce the following output:
                                                                                                                    array class name       = [I
    element class name     = java.lang.Integer
    array type name        = [I
    array type description = 1-dimension array of int
Parameters: `elementType` - the `SimpleType` of the element values contained in the arrays described by this `ArrayType` instance. `primitiveArray` - `true` when this array describes primitive arrays. Throws: `IllegalArgumentException` - if `dimension` is not a positive integer. `OpenDataException` - if `primitiveArray` is `true` and `elementType` is not a valid `SimpleType` for a primitive type. Since: 1.6

### method:getDimension() [NONE]
### getDimension public int getDimension() Returns the dimension of arrays described by this `ArrayType` instance. Returns: the dimension.

### method:getElementOpenType() [NONE]
### getElementOpenType public OpenType<?> getElementOpenType() Returns the open type of element values contained in the arrays described by this `ArrayType` instance. Returns: the element type.

### method:isPrimitiveArray() [NONE]
### isPrimitiveArray public boolean isPrimitiveArray() Returns `true` if the open data values this open type describes are primitive arrays, `false` otherwise. Returns: true if this is a primitive array type. Since: 1.6

### method:isValue(java.lang.Object) [NONE]
### isValue public boolean isValue (Object obj) Tests whether obj is a value for this `ArrayType` instance. This method returns `true` if and only if obj is not null, obj is an array and any one of the following is `true`: if this `ArrayType` instance describes an array of `SimpleType` elements or their corresponding primitive types, obj's class name is the same as the className field defined for this `ArrayType` instance (i.e. the class name returned by the `getClassName` method, which includes the dimension information), if this `ArrayType` instance describes an array of classes implementing the `TabularData` interface or the `CompositeData` interface, obj is assignable to such a declared array, and each element contained in {obj is either null or a valid value for the element's open type specified by this `ArrayType` instance. Specified by: `isValue` in class `OpenType<T>` Parameters: `obj` - the object to be tested. Returns: `true` if obj is a value for this `ArrayType` instance.

### method:equals(java.lang.Object) [NONE]
### equals public boolean equals (Object obj) Compares the specified `obj` parameter with this `ArrayType` instance for equality. Two `ArrayType` instances are equal if and only if they describe array instances which have the same dimension, elements' open type and primitive array flag. Specified by: `equals` in class `OpenType<T>` Parameters: `obj` - the object to be compared for equality with this `ArrayType` instance; if obj is `null` or is not an instance of the class `ArrayType` this method returns `false`. Returns: `true` if the specified object is equal to this `ArrayType` instance. See Also: `Object.hashCode()` `HashMap`

### method:hashCode() [NONE]
### hashCode public int hashCode() Returns the hash code value for this `ArrayType` instance. The hash code of an `ArrayType` instance is the sum of the hash codes of all the elements of information used in `equals` comparisons (i.e. dimension, elements' open type and primitive array flag). The hashcode for a primitive value is the hashcode of the corresponding boxed object (e.g. the hashcode for `true` is `Boolean.TRUE.hashCode()`). This ensures that `t1.equals(t2)` implies that `t1.hashCode()==t2.hashCode()` for any two `ArrayType` instances `t1` and `t2`, as required by the general contract of the method `Object.hashCode()`. As `ArrayType` instances are immutable, the hash code for this instance is calculated once, on the first call to `hashCode`, and then the same value is returned for subsequent calls. Overrides: `hashCode` in class `Object` Returns: the hash code value for this `ArrayType` instance See Also: `Object.equals(java.lang.Object)` `System.identityHashCode(Object)`

### method:toString() [NONE]
### toString public String toString() Returns a string representation of this `ArrayType` instance. The string representation consists of the name of this class (i.e. `javax.management.openmbean.ArrayType`), the type name, the dimension, the elements' open type and the primitive array flag defined for this instance. As `ArrayType` instances are immutable, the string representation for this instance is calculated once, on the first call to `toString`, and then the same value is returned for subsequent calls. Specified by: `toString` in class `OpenType<T>` Returns: a string representation of this `ArrayType` instance

### method:getArrayType(javax.management.openmbean.OpenType) [NONE]
### getArrayType public static <E> ArrayType<E[]> getArrayType (OpenType<E> elementType) throws OpenDataException Create an `ArrayType` instance in a type-safe manner. Multidimensional arrays can be built up by calling this method as many times as necessary. Calling this method twice with the same parameters may return the same object or two equal but not identical objects. As an example, the following piece of code:
                                                                                                                    ArrayType<String[]> t1 = ArrayType.getArrayType(SimpleType.STRING);
    ArrayType<String[][]> t2 = ArrayType.getArrayType(t1);
    ArrayType<String[][][]> t3 = ArrayType.getArrayType(t2);
    System.out.println("array class name       = " + t3.getClassName());
    System.out.println("element class name     = " + t3.getElementOpenType().getClassName());
    System.out.println("array type name        = " + t3.getTypeName());
    System.out.println("array type description = " + t3.getDescription());
would produce the following output:
                                                                                                                    array class name       = [[[Ljava.lang.String;
    element class name     = java.lang.String
    array type name        = [[[Ljava.lang.String;
    array type description = 3-dimension array of java.lang.String
Type Parameters: `E` - the Java type that described instances must have Parameters: `elementType` - the open type of element values contained in the arrays described by this `ArrayType` instance; must be an instance of either `SimpleType`, `CompositeType`, `TabularType` or another `ArrayType` with a `SimpleType`, `CompositeType` or `TabularType` as its `elementType`. Returns: an `ArrayType` instance Throws: `OpenDataException` - if elementType's className is not one of the allowed Java class names for open data. Since: 1.6

### method:getPrimitiveArrayType(java.lang.Class) [NONE]
### getPrimitiveArrayType public static <T> ArrayType<T> getPrimitiveArrayType (Class<T> arrayClass) Create an `ArrayType` instance in a type-safe manner. Calling this method twice with the same parameters may return the same object or two equal but not identical objects. As an example, the following piece of code:
                                                                                                                    ArrayType<int[][][]> t = ArrayType.getPrimitiveArrayType(int[][][].class);
    System.out.println("array class name       = " + t.getClassName());
    System.out.println("element class name     = " + t.getElementOpenType().getClassName());
    System.out.println("array type name        = " + t.getTypeName());
    System.out.println("array type description = " + t.getDescription());
would produce the following output:
                                                                                                                    array class name       = [[[I
    element class name     = java.lang.Integer
    array type name        = [[[I
    array type description = 3-dimension array of int
Type Parameters: `T` - the Java type that described instances must have Parameters: `arrayClass` - a primitive array class such as `int[].class`, `boolean[][].class`, etc. The `getElementOpenType()` method of the returned `ArrayType` returns the `SimpleType` corresponding to the wrapper type of the primitive type of the array. Returns: an `ArrayType` instance Throws: `IllegalArgumentException` - if arrayClass is not a primitive array. Since: 1.6
