Interface java.awt.swing.text.AbstractDocument.AttributeContext
- Implementing Classes:
- StyleContext
- public interface AbstractDocument.AttributeContext
An interface that can be used to allow MutableAttributeSet
implementations to use pluggable attribute compression
techniques. Each mutation of the attribute set can be
used to exchange a previous AttributeSet instance with
another, preserving the possibility of the AttributeSet
remaining immutable. An implementation is provided by
the StyleContext class.
The Element implementations provided by this class use
this interface to provide their MutableAttributeSet
implementations, so that different AttributeSet compression
techniques can be employed. The method
getAttributeContext should be implemented to
return the object responsible for implementing the desired
compression technique.

addAttribute
public AttributeSet addAttribute(AttributeSet old,
Object name,
Object value)
- Adds an attribute to the given set, and returns
the new representative set.
- Parameters:
old
- the old attribute set
name
- the attribute name
value
- the attribute value
- Returns:
- the updated attribute set
- See Also:
- addAttribute
addAttributes
public AttributeSet addAttributes(AttributeSet old,
AttributeSet attr)
- Adds a set of attributes to the element.
- Parameters:
old
- the old attribute set
attr
- the attributes to add
- Returns:
- the updated attribute set
- See Also:
- addAttribute
removeAttribute
public AttributeSet removeAttribute(AttributeSet old,
Object name)
- Removes an attribute from the set.
- Parameters:
old
- the old attribute set
name
- the attribute name
- Returns:
- the updated attribute set
- See Also:
- removeAttribute
removeAttributes
public AttributeSet removeAttributes(AttributeSet old,
Enumeration names)
- Removes a set of attributes for the element.
- Parameters:
old
- the old attribute set
names
- the attribute names
- Returns:
- the updated attribute set
- See Also:
- removeAttributes
removeAttributes
public AttributeSet removeAttributes(AttributeSet old,
AttributeSet attrs)
- Removes a set of attributes for the element.
- Parameters:
old
- the old attribute set
attrs
- the attributes
- Returns:
- the updated attribute set
- See Also:
- removeAttributes
getEmptySet
public AttributeSet getEmptySet()
- Fetches an empty AttributeSet.
- Returns:
- the attribute set
reclaim
public void reclaim(AttributeSet a)
- Reclaims an attribute set.
This is a way for a MutableAttributeSet to mark that it no
longer need a particular immutable set. This is only necessary
in 1.1 where there are no weak references. A 1.1 implementation
would call this in its finalize method.
- Parameters:
a
- the attribute set to reclaim
