Constructor Detail

MBeanFeatureInfo

public MBeanFeatureInfo(String name,

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.

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.

Method Detail

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.

Specified by:

getDescriptor in interface DescriptorRead

Returns:

a descriptor that is either immutable or a copy of the original.

Since:

1.6

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 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

hashCode returns a hash code for this object. The hash code must be equal for two objects a and b if a.equals(b) is true.

The default implementation returns System.identityHashCode(this).

Overrides:

hashCode in class Object

Returns:

a hash code value.
