getInitializer()
Returns the initial value, or
null if not provided |
AstNode |
getTarget()
Returns the variable name or destructuring form
|

setInitializer(AstNode initializer)
Sets the initial value expression, and sets its parent to this node.
|
void |
setNodeType(int nodeType)
Sets the node type.
|
void |
setTarget(AstNode target)
Sets the variable name or destructuring form, and sets
its parent to this node.
|
java.lang.String |
toSource(int depth)
Emits source code for this node.
|
void |
visit(NodeVisitor v)
Visits this node, then the target expression, then the initializer
expression if present.

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.
