public class ObjectLiteral
extends AstNode
implements DestructuringForm

AST node for an Object literal (also called an Object initialiser in Ecma-262). The elements list will always be non-null, although the list will have no elements if the Object literal is empty.

Node type is Token.OBJECTLIT.

Method Summary

void	addElement(ObjectProperty element) Adds an element to the list, and sets its parent to this node.
java.util.List<ObjectProperty>	getElements() Returns the element list.
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	setElements(java.util.List<ObjectProperty> elements) Sets the element list, and updates the parent of each element.
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.
java.lang.String	toSource(int depth) Emits source code for this node.
void	visit(NodeVisitor v) Visits this node, then visits each child property node, in lexical (source) order.

Method Detail

getElements

public java.util.List<ObjectProperty> getElements()

Returns the element list. Returns an immutable empty list if there are no elements.

setElements

public void setElements(java.util.List<ObjectProperty> elements)

Sets the element list, and updates the parent of each element. Replaces any existing elements.

Parameters:

elements - the element list. Can be null.

addElement

public void addElement(ObjectProperty element)

Adds an element to the list, and sets its parent to this node.

Parameters:

element - the property node to append to the end of the list

Throws:

IllegalArgumentException} - if element is null

setIsDestructuring

public 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.

Specified by:

setIsDestructuring in interface DestructuringForm

isDestructuring

public 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.

Specified by:

isDestructuring in interface DestructuringForm

toSource

public java.lang.String toSource(int depth)

Description copied from class: AstNode

Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

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.

Specified by:

toSource in class AstNode

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

visit

public void visit(NodeVisitor v)

Visits this node, then visits each child property node, in lexical (source) order.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
