Method Details

addAttribute

public void addAttribute(Object name,
                         Object value)
Adds an attribute with the given name and value to the set. If the set already contains an attribute with the given name, the attribute value is updated.
Parameters:
name - the attribute name (null not permitted).
value - the value (null not permitted).
Throws:

removeAttributes

public void removeAttributes(AttributeSet attributes)
Removes attributes from this set if they are found in the given set. Only attributes whose key AND value are removed. Removes attributes only from this set, not from the resolving parent.

Parameters:

setResolveParent

public void setResolveParent(AttributeSet parent)
Sets the reolving parent for this set. When looking up an attribute, if it is not found in this set, then the resolving parent is also used for the lookup.
