public class MBeanOperationInfo

extends MBeanFeatureInfo

implements Serializable, Cloneable

Describes an operation exposed by an MBean This implementation protects its immutability by taking shallow clones of all arrays supplied in constructors and by returning shallow array clones in getXXX() methods.

Constructor Detail

MBeanOperationInfo

public MBeanOperationInfo(String description,
                          Method method)

Constructs management operation metadata from a given Method object and description.

Parameters:

description - human readable description of this operation

method - used for build the metadata for the management operation

---

MBeanOperationInfo

public MBeanOperationInfo(String name,
                          String description,
                          MBeanParameterInfo[] signature,
                          String returnType,
                          int impact)

Constructs a management operation metadata.

Parameters:

name - name of the management operation

description - human readable description string of the operation

signature - signature of the operation

returnType - return type of the operation as a fully qualified class name

impact - impact of this operation: ACTION, INFO, ACTION_INFO or UNKNOWN

Throws:

IllegalArgumentException - if the name or return type is not a valid java identifier or it is a reserved word or the impact is invalid

Method Detail

getReturnType

public String getReturnType()

Returns a fully qualified class name of the return type of this operation.

Returns:

fully qualified class name

---

getSignature

public MBeanParameterInfo[] getSignature()

Returns the signature of this operation. Note: an operation with a void signature returns a zero-length array, not a null reference.

Returns:

operation's signature

---

getImpact

public int getImpact()

Returns the impact of this operation. The impact is one of the following values: ACTION, INFO, ACTION_INFO or UNKNOWN (reserved for Standard MBeans).

Returns:

operation's impact

---

equals

public boolean equals(Object object)

Overrides:

equals in class MBeanFeatureInfo

---

hashCode

public int hashCode()

Overrides:

hashCode in class MBeanFeatureInfo

---

toString

public String toString()

Overrides:

toString in class MBeanFeatureInfo

Returns:

a human readable string

---

clone

public Object clone()
             throws CloneNotSupportedException

Creates a copy of this object. This is a deep copy; the MBeanParameterInfo objects forming the operation's signature are also cloned.

Returns:

a clone of this object

Throws:

CloneNotSupportedException - if there was a failure trying to copy the object
