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 (for prefix operators) or from
the start of the operand to the operator (for postfix).
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.

AstNode |
getOperand() |
int |
getOperator()
Returns operator token – alias for
Node.getType() |
boolean |
isPostfix()
Returns whether the operator is postfix
|
boolean |
isPrefix()
Returns whether the operator is prefix
|
void |
setIsPostfix(boolean isPostfix)
Sets whether the operator is postfix
|
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.
