Package Summary Overview Summary

### class:OpenMBeanOperationInfoSupport [NONE]
All Implemented Interfaces: `Serializable, Cloneable, DescriptorRead, OpenMBeanOperationInfo` public class OpenMBeanOperationInfoSupport extends MBeanOperationInfo implements OpenMBeanOperationInfo Describes an operation of an Open MBean. Since: 1.5 See Also: Serialized Form

### constructor:OpenMBeanOperationInfoSupport(java.lang.String,java.lang.String,javax.management.openmbean.OpenMBeanParameterInfo[],javax.management.openmbean.OpenType,int) [NONE]
### OpenMBeanOperationInfoSupport public OpenMBeanOperationInfoSupport (String name, String description, OpenMBeanParameterInfo[] signature, OpenType<?> returnOpenType, int impact) Constructs an `OpenMBeanOperationInfoSupport` instance, which describes the operation of a class of open MBeans, with the specified `name`, `description`, `signature`, `returnOpenType` and `impact` . The `signature` array parameter is internally copied, so that subsequent changes to the array referenced by `signature` have no effect on this instance. Parameters: `name` - cannot be a null or empty string. `description` - cannot be a null or empty string. `signature` - can be null or empty if there are no parameters to describe. `returnOpenType` - cannot be null: use `SimpleType.VOID` for operations that return nothing. `impact` - must be one of `ACTION`, `ACTION_INFO` , `INFO`, or `UNKNOWN`. Throws: `IllegalArgumentException` - if `name` or `description` are null or empty string, or `returnOpenType` is null, or `impact` is not one of `ACTION` , `ACTION_INFO`, `INFO`, or `UNKNOWN`. `ArrayStoreException` - If `signature` is not an array of instances of a subclass of `MBeanParameterInfo`.

### constructor:OpenMBeanOperationInfoSupport(java.lang.String,java.lang.String,javax.management.openmbean.OpenMBeanParameterInfo[],javax.management.openmbean.OpenType,int,javax.management.Descriptor) [NONE]
### OpenMBeanOperationInfoSupport public OpenMBeanOperationInfoSupport (String name, String description, OpenMBeanParameterInfo[] signature, OpenType<?> returnOpenType, int impact, Descriptor descriptor) Constructs an `OpenMBeanOperationInfoSupport` instance, which describes the operation of a class of open MBeans, with the specified `name`, `description`, `signature`, `returnOpenType`, `impact` , and `descriptor`. The `signature` array parameter is internally copied, so that subsequent changes to the array referenced by `signature` have no effect on this instance. Parameters: `name` - cannot be a null or empty string. `description` - cannot be a null or empty string. `signature` - can be null or empty if there are no parameters to describe. `returnOpenType` - cannot be null: use `SimpleType.VOID` for operations that return nothing. `impact` - must be one of `ACTION`, `ACTION_INFO` , `INFO`, or `UNKNOWN`. `descriptor` - The descriptor for the operation. This may be null, which is equivalent to an empty descriptor. Throws: `IllegalArgumentException` - if `name` or `description` are null or empty string, or `returnOpenType` is null, or `impact` is not one of `ACTION` , `ACTION_INFO`, `INFO`, or `UNKNOWN`. `ArrayStoreException` - If `signature` is not an array of instances of a subclass of `MBeanParameterInfo`. Since: 1.6

### method:getReturnOpenType() [NONE]
### getReturnOpenType public OpenType<?> getReturnOpenType() Returns the open type of the values returned by the operation described by this `OpenMBeanOperationInfo` instance. Specified by: `getReturnOpenType` in interface `OpenMBeanOperationInfo` Returns: the return type.

### method:equals(java.lang.Object) [NONE]
### equals public boolean equals (Object obj) Compares the specified `obj` parameter with this `OpenMBeanOperationInfoSupport` instance for equality. Returns `true` if and only if all of the following statements are true: `obj` is non null, `obj` also implements the `OpenMBeanOperationInfo` interface, their names are equal their signatures are equal their return open types are equal their impacts are equal This ensures that this `equals` method works properly for `obj` parameters which are different implementations of the `OpenMBeanOperationInfo` interface. Specified by: `equals` in interface `OpenMBeanOperationInfo` Overrides: `equals` in class `MBeanOperationInfo` Parameters: `obj` - the object to be compared for equality with this `OpenMBeanOperationInfoSupport` instance; Returns: `true` if the specified object is equal to this `OpenMBeanOperationInfoSupport` instance. See Also: `Object.hashCode()` `HashMap`

### method:hashCode() [NONE]
### hashCode public int hashCode() Returns the hash code value for this `OpenMBeanOperationInfoSupport` instance. The hash code of an `OpenMBeanOperationInfoSupport` instance is the sum of the hash codes of all elements of information used in `equals` comparisons (ie: its name, return open type, impact and signature, where the signature hashCode is calculated by a call to `java.util.Arrays.asList(this.getSignature).hashCode()` ). This ensures that `t1.equals(t2)` implies that `t1.hashCode()==t2.hashCode()` for any two `OpenMBeanOperationInfoSupport` instances `t1` and `t2` , as required by the general contract of the method `Object.hashCode()`. However, note that another instance of a class implementing the `OpenMBeanOperationInfo` interface may be equal to this `OpenMBeanOperationInfoSupport` instance as defined by `equals(java.lang.Object)`, but may have a different hash code if it is calculated differently. As `OpenMBeanOperationInfoSupport` 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. Specified by: `hashCode` in interface `OpenMBeanOperationInfo` Overrides: `hashCode` in class `Object` Returns: the hash code value for this `OpenMBeanOperationInfoSupport` instance See Also: `Object.equals(java.lang.Object)` `System.identityHashCode(Object)`

### method:toString() [NONE]
### toString public String toString() Returns a string representation of this `OpenMBeanOperationInfoSupport` instance. The string representation consists of the name of this class (ie `javax.management.openmbean.OpenMBeanOperationInfoSupport` ), and the name, signature, return open type and impact of the described operation and the string representation of its descriptor. As `OpenMBeanOperationInfoSupport` 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 interface `OpenMBeanOperationInfo` Overrides: `toString` in class `Object` Returns: a string representation of this `OpenMBeanOperationInfoSupport` instance
