All Implemented Interfaces:

Expression, ExpressionContainer, ModelElement, NonTerminalProgramElement, ProgramElement, SourceElement, SVSubstitute

public class ArrayInitializer
extends JavaNonTerminalProgramElement
implements Expression, ExpressionContainer

An ArrayInitializer is a valid expression exclusively for initializing ArrayTypes. Any other expressions are suited for any expression node. These rules could have been expressed by appropriate types, but these solutions would require a couple of new interfaces which did not seem adequate. The parent expression is either another ArrayInitializer (nested blocks) or a VariableDeclaration.
