Examples of org.eclipse.jdt.core.dom.ChildListPropertyDescriptor

org.eclipse.jdt.core.dom.ChildListPropertyDescriptor
Descriptor for a child list property of an AST node. A child list property is one whose value is a list of {@link ASTNode}. @see org.eclipse.jdt.core.dom.ASTNode#getStructuralProperty(StructuralPropertyDescriptor) @since 3.0 @noinstantiate This class is not intended to be instantiated by clients.
