| Modifier and Type | Method and Description |
|---|---|
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.
