 javax.management.modelmbean.ModelMBeanAttributeInfo
| ModelMBeanAttributeInfo | | public class ModelMBeanAttributeInfo extends MBeanAttributeInfo implements DescriptorAccess,Cloneable(Code) | | The ModelMBeanAttributeInfo object describes an attribute of the ModelMBean.
It is a subclass of MBeanAttributeInfo with the addition of an associated Descriptor
and an implementation of the DescriptorAccess interface.
The fields in the descriptor are defined, but not limited to, the following:
name : attribute name
descriptorType : must be "attribute"
value : current value for attribute
default : default value for attribute
displayName : name of attribute to be used in displays
getMethod : name of operation descriptor for get method
setMethod : name of operation descriptor for set method
protocolMap : object which implements the ProtocolMap interface: map of protocol names and protocol hints
persistPolicy : Update|OnTime|NoMoreOftenThan|Always|Never
persistPeriod : seconds - frequency of persist cycle. Used when persistPolicy is"OnTime" or "NoMoreOftenThan".
currencyTimeLimit : how long value is valid, <0 never, =0 always, >0 seconds
lastUpdatedTimeStamp : when value was set
iterable : T - object value supports Iterable interface, F - does not support Iterable interface
visibility : 1-4 where 1: always visible 4: rarely visible
presentationString : xml formatted string to allow presentation of data
The default descriptor contains the name and descriptorType fields.

| ModelMBeanAttributeInfo | | public ModelMBeanAttributeInfo(String name, String description, Method getter, Method setter) throws IntrospectionException(Code) | | Constructs a ModelMBeanAttributeInfo object with a default descriptor.
Parameters:
name - The name of the attribute.
Parameters:
description - A human readable description of the attribute. Optional.
Parameters:
getter - The method used for reading the attribute value.May be null if the property is write-only.
Parameters:
