public interface IAttributeSupport

This interface declares support for "generic attributes".

This means the object implementing this interface may be extended transparently by its clients with name/value pairs. These attributes and their values are stored but not interpreted by the object that implements this interface.

Method Summary

Object	getAttribute(Object key) get an attribute from the context
Object	removeAttribute(Object key) remove an attribute in the context
Object	setAttribute(Object key, Object o) set the value of an attribute in the context

Method Detail

setAttribute

Object setAttribute(Object key,
                    Object o)

set the value of an attribute in the context

Parameters:

key - the name of the attribute to set

o - the new value the attribute

Returns:

The previously associated object for key

getAttribute

Object getAttribute(Object key)

get an attribute from the context

Parameters:

key - the name of the attribute to get

Returns:

The value of the attribute to get

removeAttribute

Object removeAttribute(Object key)

remove an attribute in the context

Parameters:

key - the name of the attribute to remove

Returns:

The previously associated object for key
