public class ObjectLiteral
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
.
ObjectLiteral : {} { PropertyNameAndValueList } PropertyNameAndValueList : PropertyName : AssignmentExpression PropertyNameAndValueList , PropertyName : AssignmentExpression PropertyName : Identifier StringLiteral NumericLiteral

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. |

AstNode
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.
toSource
in class AstNode
depth
- the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit
in class AstNode
v
- the object to call with this node and its children
