public class Name extends AstNode
Token.NAME.This node type is also used to represent certain non-identifier names that are part of the language syntax. It's used for the "get" and "set" pseudo-keywords for object-initializer getter/setter properties, and it's also used for the "*" wildcard in E4X XML namespace and name expressions.

public java.lang.String getIdentifier()
public void setIdentifier(java.lang.String identifier)
java.lang.IllegalArgumentException - if identifier is nullpublic void setScope(Scope s)
Scope associated with this node. This method does not
set the scope's ast-node field to this node. The field exists only
for temporary storage by the code generator. Not every name has an
associated scope - typically only function and variable names (but not
property names) are registered in a scope.public Scope getScope()
Scope associated with this node. This is
only used for (and set by) the code generator, so it will always
be null in frontend AST-processing code. Use getDefiningScope()
to find the lexical Scope in which this Name is defined,
if any.public Scope getDefiningScope()
Scope in which this Name is defined.null
if it's not defined in the current lexical scope chainpublic boolean isLocalName()
true if this name appears as local variable, a let-bound
variable not in the global scope, a function parameter, a loop
variable, the property named in a PropertyGet, or in any other
context where the node is known not to resolve to the global scope.
Returns false if the node is defined in the top-level scope
(i.e., its defining scope is an AstRoot object), or if its
name is not defined as a symbol in the symbol table, in which case it
may be an external or built-in name (or just an error of some sort.)public int length()
String. Don't confuse this method with the
AstNode.getLength() method, which returns the range of
characters that this node overlaps in the source input.public java.lang.String toSource(int depth)
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.
