Class JmxProperties

java.lang.Object
  org.xmlBlaster.util.admin.extern.JmxProperties

All Implemented Interfaces:

javax.management.DynamicMBean

public class JmxProperties
extends java.lang.Object
implements javax.management.DynamicMBean

Definition of a dynamic MBean which exports the Global properties. The "JmxProperties" dynamic MBean shows how to expose for management attributes and operations, at runtime, by implementing the "javax.management.DynamicMBean" interface. This MBean exposes for management all glob.getProperty() key/values. - the read/write attribute, - the read only attribute, - the "set()" operation. It does so by putting this information in an MBeanInfo object that is returned by the getMBeanInfo() method of the DynamicMBean interface. It implements the access to its attributes through the getAttribute(), getAttributes(), setAttribute(), and setAttributes() methods of the DynamicMBean interface. It implements the invocation of its set() operation through the invoke() method of the DynamicMBean interface. Note that as "JmxProperties" explicitly defines one constructor, this constructor must be public and exposed for management through the MBeanInfo object.

Since:

1.0.4

Specified by:

setAttribute in interface javax.management.DynamicMBean

Throws:

javax.management.AttributeNotFoundException

javax.management.InvalidAttributeValueException

javax.management.MBeanException

javax.management.ReflectionException

isReadOnly

private boolean isReadOnly(java.lang.String name)

getAttributes

public javax.management.AttributeList getAttributes(java.lang.String[] attributeNames)

Enables the to get the values of several attributes of the Dynamic MBean.

Specified by:

getAttributes in interface javax.management.DynamicMBean

setAttributes

public javax.management.AttributeList setAttributes(javax.management.AttributeList attributes)

Sets the values of several attributes of the Dynamic MBean, and returns the list of attributes that have been set.

Specified by:

setAttributes in interface javax.management.DynamicMBean

invoke

public java.lang.Object invoke(java.lang.String operationName,
                               java.lang.Object[] params,
                               java.lang.String[] signature)
                        throws javax.management.MBeanException,
                               javax.management.ReflectionException

Allows an operation to be invoked on the Dynamic MBean.

Specified by:

invoke in interface javax.management.DynamicMBean

Throws:

javax.management.MBeanException

javax.management.ReflectionException

getMBeanInfo

public javax.management.MBeanInfo getMBeanInfo()

This method provides the exposed attributes and operations of the Dynamic MBean. It provides this information using an MBeanInfo object.

Specified by:

getMBeanInfo in interface javax.management.DynamicMBean

buildDynamicMBeanInfo

private void buildDynamicMBeanInfo()

Build the private dMBeanInfo field, which represents the management interface exposed by the MBean; that is, the set of attributes, constructors, operations and notifications which are available for management. A reference to the dMBeanInfo object is returned by the getMBeanInfo() method of the DynamicMBean interface. Note that, once constructed, an MBeanInfo object is immutable.
