public JsUnaryOperation(JsUnaryOperator op,
                        JsExpression arg)

Method Detail

getArg

public JsExpression getArg()

getOperator

public JsUnaryOperator getOperator()

setArg

public void setArg(JsExpression arg)

acceptChildren

public void acceptChildren(JsVisitor visitor)

Specified by:

acceptChildren in interface JsNode

traverse

public void traverse(JsVisitorWithContext v,
                     JsContext ctx)

Description copied from interface: JsNode

Causes this object to have the visitor visit itself and its children.

Parameters:

Description copied from interface: JsNode

Return the source info associated with this object.

setSource

public void setSource(java.lang.Object info)

Description copied from interface: JsNode

Set the source info associated with this object.

toString

public java.lang.String toString()

withMetadataFrom
