- * Array creation expression AST node type.
- * For JLS2:
- * <pre>
- * ArrayCreation:
- * <b>new</b> PrimitiveType <b>[</b> Expression <b>]</b> { <b>[</b> Expression <b>]</b> } { <b>[</b> <b>]</b> }
- * <b>new</b> TypeName <b>[</b> Expression <b>]</b> { <b>[</b> Expression <b>]</b> } { <b>[</b> <b>]</b> }
- * <b>new</b> PrimitiveType <b>[</b> <b>]</b> { <b>[</b> <b>]</b> } ArrayInitializer
- * <b>new</b> TypeName <b>[</b> <b>]</b> { <b>[</b> <b>]</b> } ArrayInitializer
- * </pre>
- * <p>
- * The mapping from Java language syntax to AST nodes is as follows:
- * <ul>
- * <li>the type node is the array type of the creation expression,
- * with one level of array per set of square brackets,</li>
- * <li>the dimension expressions are collected into the <code>dimensions</code>
- * list.</li>
- * </ul>
- * </p>
- * For JLS3, type arguments are added:
- * <pre>
- * ArrayCreation:
- * <b>new</b> PrimitiveType <b>[</b> Expression <b>]</b> { <b>[</b> Expression <b>]</b> } { <b>[</b> <b>]</b> }
- * <b>new</b> TypeName [ <b><</b> Type { <b>,</b> Type } <b>></b> ]
- * <b>[</b> Expression <b>]</b> { <b>[</b> Expression <b>]</b> } { <b>[</b> <b>]</b> }
- * <b>new</b> PrimitiveType <b>[</b> <b>]</b> { <b>[</b> <b>]</b> } ArrayInitializer
- * <b>new</b> TypeName [ <b><</b> Type { <b>,</b> Type } <b>></b> ]
- * <b>[</b> <b>]</b> { <b>[</b> <b>]</b> } ArrayInitializer
- * </pre>
