| Modifier and Type | Method and Description | 
|---|---|
| void | addElement(AstNode element)Adds an element to the list, and sets its parent to this node. | 
| int | getDestructuringLength()Returns destructuring length | 
| AstNode | getElement(int index)Returns element at specified index. | 
| java.util.List<AstNode> | getElements()Returns the element list | 
| int | getSize()Returns the number of elements in this  Arrayliteral,
 including empty elements. | 
| int | getSkipCount()Used by code generator. | 
| boolean | isDestructuring()Returns true if this node is in a destructuring position:
 a function parameter, the target of a variable initializer, the
 iterator of a for..in loop, etc. | 
| void | setDestructuringLength(int destructuringLength)Sets destructuring length. | 
| void | setElements(java.util.List<AstNode> elements)Sets the element list, and sets each element's parent to this node. | 
| void | setIsDestructuring(boolean destructuring)Marks this node as being a destructuring form - that is, appearing
 in a context such as  for ([a, b] in ...)where it's the
 target of a destructuring assignment. | 
| void | setSkipCount(int count)Used by code generator. | 
| java.lang.String | toSource(int depth)Emits source code for this node. | 
| void | visit(NodeVisitor v)Visits this node, then visits its element expressions in order. |

 Note: if the parser was in error-recovery mode, some AST nodes may have
 null children that are expected to be non-null
 when no errors are present.  In this situation, the behavior of the
 toSource method is undefined: toSource
 implementations may assume that the AST node is error-free, since it is
 intended to be invoked only at runtime after a successful parse.
