getAttribute

public final Object getAttribute(Object key)

Get a generic attribute value.

ATTENTION: to speed up a little, an IdentityHashMap is used for implementing IAttributeSupport. Be sure to use appropriate keys (for example Attribute), not String.

Specified by:

getAttribute in interface de.intarsys.tools.attribute.IAttributeSupport

IAttributeSupport.getAttribute(java.lang.Object)

removeAttribute

public final Object removeAttribute(Object key)

Clear a generic attribute value.

ATTENTION: to speed up a little, an IdentityHashMap is used for implementing IAttributeSupport. Be sure to use appropriate keys (for example Attribute), not String.

Specified by:

removeAttribute in interface de.intarsys.tools.attribute.IAttributeSupport

IAttributeSupport.removeAttribute(java.lang.Object)

setAttribute

public final Object setAttribute(Object key,
                  Object value)

Set a generic attribute value.
