Package Summary Overview Summary

### class:MBeanOperationInfo [NONE]
All Implemented Interfaces: `Serializable, Cloneable, DescriptorRead` Direct Known Subclasses: `ModelMBeanOperationInfo, OpenMBeanOperationInfoSupport` public class MBeanOperationInfo extends MBeanFeatureInfo implements Cloneable Describes a management operation exposed by an MBean. Instances of this class are immutable. Subclasses may be mutable but this is not recommended. Since: 1.5 See Also: Serialized Form

### field:INFO [NONE]
### INFO public static final int INFO Indicates that the operation is read-like: it returns information but does not change any state. See Also: Constant Field Values

### field:ACTION [NONE]
### ACTION public static final int ACTION Indicates that the operation is write-like: it has an effect but does not return any information from the MBean. See Also: Constant Field Values

### field:ACTION_INFO [NONE]
### ACTION_INFO public static final int ACTION_INFO Indicates that the operation is both read-like and write-like: it has an effect, and it also returns information from the MBean. See Also: Constant Field Values

### field:UNKNOWN [NONE]
### UNKNOWN public static final int UNKNOWN Indicates that the impact of the operation is unknown or cannot be expressed using one of the other values. See Also: Constant Field Values

### constructor:MBeanOperationInfo(java.lang.String,java.lang.reflect.Method) [NONE]
### MBeanOperationInfo public MBeanOperationInfo (String description, Method method) Constructs an `MBeanOperationInfo` object. The `Descriptor` of the constructed object will include fields contributed by any annotations on the `Method` object that contain the `DescriptorKey` meta-annotation. Parameters: `description` - A human readable description of the operation. `method` - The `java.lang.reflect.Method` object describing the MBean operation.

### constructor:MBeanOperationInfo(java.lang.String,java.lang.String,javax.management.MBeanParameterInfo[],java.lang.String,int) [NONE]
### MBeanOperationInfo public MBeanOperationInfo (String name, String description, MBeanParameterInfo[] signature, String type, int impact) Constructs an `MBeanOperationInfo` object. Parameters: `name` - The name of the method. `description` - A human readable description of the operation. `signature` - `MBeanParameterInfo` objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array. `type` - The type of the method's return value. `impact` - The impact of the method, one of `INFO`, `ACTION`, `ACTION_INFO`, `UNKNOWN`.

### constructor:MBeanOperationInfo(java.lang.String,java.lang.String,javax.management.MBeanParameterInfo[],java.lang.String,int,javax.management.Descriptor) [NONE]
### MBeanOperationInfo public MBeanOperationInfo (String name, String description, MBeanParameterInfo[] signature, String type, int impact, Descriptor descriptor) Constructs an `MBeanOperationInfo` object. Parameters: `name` - The name of the method. `description` - A human readable description of the operation. `signature` - `MBeanParameterInfo` objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array. `type` - The type of the method's return value. `impact` - The impact of the method, one of `INFO`, `ACTION`, `ACTION_INFO`, `UNKNOWN`. `descriptor` - The descriptor for the operation. This may be null which is equivalent to an empty descriptor. Throws: `IllegalArgumentException` - if `impact` is not one of ACTION, ACTION_INFO, INFO or UNKNOWN. Since: 1.6

### method:clone() [NONE]
### clone public Object clone() Returns a shallow clone of this instance. The clone is obtained by simply calling `super.clone()`, thus calling the default native shallow cloning mechanism implemented by `Object.clone()`. No deeper cloning of any internal field is made. Since this class is immutable, cloning is chiefly of interest to subclasses. Overrides: `clone` in class `Object` Returns: a clone of this instance. See Also: `Cloneable`

### method:getReturnType() [NONE]
### getReturnType public String getReturnType() Returns the type of the method's return value. Returns: the return type.

### method:getSignature() [NONE]
### getSignature public MBeanParameterInfo[] getSignature() Returns the list of parameters for this operation. Each parameter is described by an `MBeanParameterInfo` object. The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the `MBeanParameterInfo` objects but that each referenced `MBeanParameterInfo` object is not copied. Returns: An array of `MBeanParameterInfo` objects.

### method:getImpact() [NONE]
### getImpact public int getImpact() Returns the impact of the method, one of `INFO, ACTION, ACTION_INFO, UNKNOWN` . Returns: the impact code.

### method:equals(java.lang.Object) [NONE]
### equals public boolean equals (Object o) Compare this MBeanOperationInfo to another. Overrides: `equals` in class `MBeanFeatureInfo` Parameters: `o` - the object to compare to. Returns: true if and only if `o` is an MBeanOperationInfo such that its `MBeanFeatureInfo.getName()`, `getReturnType()`, `MBeanFeatureInfo.getDescription()`, `getImpact()`, `MBeanFeatureInfo.getDescriptor()` and `getSignature()` values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal. See Also: `Object.hashCode()` `HashMap`
