Method Detail

endVisit

public void endVisit(JsArrayAccess x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsBinaryOperation x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsInvocation x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsNameRef x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsNew x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsPostfixOperation x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

endVisit

public void endVisit(JsPrefixOperation x,
                     JsContext ctx)

Overrides:

endVisit in class JsVisitor

visit

public boolean visit(JsFor x,
                     JsContext ctx)

This is essentially a hacked-up version of JsFor.traverse to account for flow control differing from visitation order. It resets lastFile and lastLine before the condition and increment expressions in the for loop so that location data will be recorded correctly.

Overrides:

visit in class JsVisitor

visit

public boolean visit(JsInvocation x,
                     JsContext ctx)

Overrides:

visit in class JsVisitor

visit

public boolean visit(JsPrefixOperation x,
                     JsContext ctx)

Overrides:

visit in class JsVisitor

visit

public boolean visit(JsWhile x,
                     JsContext ctx)

Similar to JsFor, this resets the current location information before evaluating the condition.

Overrides:

visit in class JsVisitor

endVisit

protected abstract void endVisit(JsExpression x,
                                 JsContext ctx)
