org.mozilla.javascript.Node
org.mozilla.javascript.ast.AstNode

org.mozilla.javascript.ast.NewExpression
- All Implemented Interfaces:
Comparable<AstNode>, Iterable<Node>
New expression. Node type is
Token.NEW
.
NewExpression : MemberExpression new NewExpressionThis node is a subtype of
FunctionCall
, mostly for internal code
sharing. Structurally a NewExpression
node is very similar to a
FunctionCall
, so it made a certain amount of sense.-

Method Details
-
getInitializer
Returns initializer object, if any.- Returns:
- extra initializer object-literal expression, or
null
if not specified.
-
setInitializer
Sets initializer object. Rhino supports an experimental syntax of the formnew expr [ ( arglist ) ] [initializer]
, in which initializer is an object literal that is used to set additional properties on the newly-createdexpr
object.- Parameters:
initializer
- extra initializer object. Can benull
.
-
toSource
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 thetoSource
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.- Overrides:
toSource
in classFunctionCall
- Parameters:
depth
- the current recursion depth, typically beginning at 0 when called on the root node.
-
visit
Visits this node, the target, and each argument. If there is a trailing initializer node, visits that last.- Overrides:
visit
in classFunctionCall
- Parameters:
v
- the object to call with this node and its children
-
