Class MutableStyle

java.lang.Object
  nextapp.echo2.app.MutableStyle

All Implemented Interfaces:

java.io.Serializable, Style

Direct Known Subclasses:

DerivedMutableStyle

public class MutableStyle

extends java.lang.Object

implements Style

A Style implementation which may be modified. Note that modifications to the Style will not necessarily be reflected in Components that use the Style unless the Components are specifically informed of the changes, i.e., by resetting the shared style of a Component. As such, shared Styles should not be updated once they are in use by Components, as it will result in undefined behavior.
