groovy.jmx.GroovyMBean

All Implemented Interfaces:

groovy.lang.GroovyObject

public class GroovyMBean
extends groovy.lang.GroovyObjectSupport

A GroovyObject facade for an underlying MBean which acts like a normal groovy object but which is actually implemented via an underlying JMX MBean. Properties and normal method invocations delegate to the MBeanServer to the actual MBean.

invokeMethod

public Object invokeMethod(String method, Object arguments)

createSignature

protected String[] createSignature(MBeanOperationInfo info)

createOperationKey

protected String createOperationKey(String operation, int params)

Construct a simple key based on the method name and the number of parameters

Parameters:

operation - - the mbean operation name

params - - the number of parameters the operation supports

public Collection<String> listAttributeNames()

List of the names of each of the attributes on the MBean

Returns:

list of attribute names

listAttributeValues

public List<String> listAttributeValues()

The values of each of the attributes on the MBean

Returns:

list of values of each attribute

listAttributeDescriptions

public Collection<String> listAttributeDescriptions()

List of string representations of all of the attributes on the MBean.

Returns:

list of descriptions of each attribute on the mbean

describeAttribute

Description of the specified attribute name.

Parameters:

attributeName - - stringified name of the attribute

Returns:

the description

listOperationNames

public Collection<String> listOperationNames()

Names of all the operations available on the MBean.

Returns:

all the operations on the MBean

Parameters:

operationName - the name of the operation to describe

Returns:

Collection of operation description

describeOperation

protected String describeOperation(MBeanOperationInfo operation)

Description of the operation.

Parameters:

operation - the operation to describe
