the previous value of the attribute if set, else null

getAttribute

public Object getAttribute(String name)

Description copied from interface: Attributes

Get an attribute by name. Some attributes may be "hidden" attributes, in that they are only found by an explicit call to getAttribute(String) and they do not otherwise appear in Attributes.getAttributeNameSet() or Attributes.asAttributeMap().

Specified by:

getAttribute in interface Attributes

Parameters:

name - the attribute to get

Returns:

the value of the attribute, or null if no such attribute exists

getAttributeNameSet

public Set<String> getAttributeNameSet()

Description copied from interface: Attributes

Get the immutable set of attribute names.

Specified by:

getAttributeNameSet in interface Attributes

Returns:

Set of attribute names, or an empty set if there are no attributes.

clearAttributes

public void clearAttributes()

Description copied from interface: Attributes

Clear all attribute names

Specified by:

dump

public String dump()

Specified by:

dump

public void dump(Appendable out,
 String indent)
          throws IOException

Description copied from interface: Dumpable
