Class ElementAttribute

java.lang.Object
com.adobe.fontengine.inlineformatting.ElementAttribute
All Implemented Interfaces:
Attribute
public final class ElementAttribute extends Object implements Attribute
This class defines attributes which can be placed on elements on AttributedRuns.

In addition to defining the type for element attribute keys, this class defines a number of well-known element attributes, and in particular all the attributes which are exchanged between an inline formatter and its clients. For each such attribute, we define the possible values.

Other ElementAttribute objects can be created and used by the client of an inline formatter. However, these keys will be ignored by the inline formatters of this package.

Concurrency

Instances of this class are immutable after construction and contain no mutable static data. Therefore, they are threadsafe.
