Class StyleDescriptorBuilder

java.lang.Object
  com.tensegrity.composite.style.persistence.StyleDescriptorBuilder

All Implemented Interfaces:

Builder

public class StyleDescriptorBuilder

extends java.lang.Object

implements Builder

The StyleDescriptorBuilder restores StyleDescriptor instances from an AttributeList. The style items arent restored here and must be available through the StyleItemPool, because the StyleDescriptorSerializer only stores the names of these items (to avoid redundancy).
