public class MBeanFeatureInfo
- extends Object
- implements Serializable, DescriptorRead
Provides general information for an MBean descriptor object. The feature described can be an attribute, an operation, a parameter, or a notification. Instances of this class are immutable. Subclasses may be mutable but this is not recommended.

name
protected String name
-
The name of the feature. It is recommended that subclasses call
getName()
rather than reading this field, and that they not change it.
description
protected String description
-
The human-readable description of the feature. It is recommended that subclasses call
getDescription()
rather than reading this field, and that they not change it.
MBeanFeatureInfo
public MBeanFeatureInfo(String name,
String description)
-
Constructs an MBeanFeatureInfo object. This constructor is equivalent to MBeanFeatureInfo(name, description, (Descriptor) null.
-
Parameters:
-
name - The name of the feature.
-
description - A human readable description of the feature.
MBeanFeatureInfo
public MBeanFeatureInfo(String name,
String description,
Descriptor descriptor)
-
Constructs an MBeanFeatureInfo object.
-
Parameters:
-
name - The name of the feature.
-
description - A human readable description of the feature.
-
descriptor - The descriptor for the feature.
This may be null which is equivalent to an empty descriptor.
This may be null in which case the feature's descriptor will be empty.

1.6
getName
public String getName()
-
Returns the name of the feature.
-
-
-
Returns:
-
the name of the feature.
getDescription
public String getDescription()
-
Returns the human-readable description of the feature.
-
-
-
Returns:
-
the human-readable description of the feature.
getDescriptor
public Descriptor getDescriptor()
-
Returns the descriptor for the feature. Changing the returned value will have no affect on the original descriptor.
-
-
Specified by:
-
getDescriptor
in interface
DescriptorRead
-
-
Returns:
-
a descriptor that is either immutable or a copy of the original.

Since:

equals
public boolean equals(Object o)
-
Compare this MBeanFeatureInfo to another.
-
-
Overrides:
-
equals
in class
Object
-
-
Parameters:
-
o - the object to compare to.
-
Returns:
-
true
if and only if
iff
o is an MBeanFeatureInfo such that its
getName()
,
getDescription()
, and
getDescriptor()
values are equal (not necessarily identical) to those of this MBeanFeatureInfo. -

hashCode
public int hashCode()
-
Description copied from class:
Object
-
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
The general contract of hashCode is:
-
Whenever it is invoked on the same object more than once during an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used in
equals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
-
If two objects are equal according to the
equals(Object)
method, then calling the hashCode method on each of the two objects must produce the same integer result.
-
It is not required that if two objects are unequal according to the
Object.equals(java.lang.Object)
method, then calling the
hashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class
Object
does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java
TM
programming language.)
