public class UnaryExpression extends AstNode
typeof
and delete
.
The type field is set to the appropriate Token type for the operator.
The node length spans from the operator to the end of the operand.
The default xml namespace = <expr>
statement in E4X
(JavaScript 1.6) is represented as a UnaryExpression
of node
type Token.DEFAULTNAMESPACE
, wrapped with an
ExpressionStatement
.

Modifier and Type | Method and Description |
---|---|
AstNode |
getOperand() |
int |
getOperator()
Returns operator token – alias for
Node.getType() |
void |
setOperand(AstNode operand)
Sets the operand, and sets its parent to be this node.
|
void |
setOperator(int operator)
Sets operator – same as
Node.setType(int) , but throws an
exception if the operator is invalid |
java.lang.String |
toSource(int depth)
Emits source code for this node.
|
void |
visit(NodeVisitor v)
Visits this node, then the operand.

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.
