Class ModelMBeanAttributeInfo

java.lang.Object
  javax.management.MBeanFeatureInfo
      javax.management.MBeanAttributeInfo
          javax.management.modelmbean.ModelMBeanAttributeInfo

All Implemented Interfaces:

Cloneable, DescriptorAccess, Serializable

---

public class ModelMBeanAttributeInfo

extends MBeanAttributeInfo

implements DescriptorAccess, Cloneable

Represents a Model MBean's management attribute.

Version:

$Revision: 1.6.4.4 $

Revisions:

20020320 Juha Lindfors:

• toString() implementation
• Changed the default descriptor to include field currencyTimeLimit with a value -1. Since default descriptors do not include method mapping this automatically caches attribute values in the Model MBean.

20020715 Adrian Brock:

• Serialization

                        throws IntrospectionException

Creates a new attribute info with a default descriptor.

Parameters:

name - name of the attribute

description - human readable description string

getter - a Method instance representing a read method for this attribute

setter - a Method instance representing a write method for this attribute

Throws:

IntrospectionException - if the accessor methods are not valid for this attribute
