Constructor Detail

CTryFinallyContext

CTryFinallyContext(CBodyContext parent)
Construct a specialized context for try/finally statement bodies.
Parameters:
parent - The parent context, it must be different than null except if called by the top level.
Method Detail

passBreakAndContinuesToParent

public void passBreakAndContinuesToParent()
                                   throws PositionedError
Forward breaks from this try context to the parent context. This is done when the breaks are not cancelled by a finally statement that doesn't complete.

addForwardedBreak

protected void addForwardedBreak(JStatement breakTo,
                                 CBodyContext from)
                          throws PositionedError
Adds a break from within this context to the specified statement.
Overrides:
addForwardedBreak in class CAbstractBodyContext

addForwardedContinue

protected void addForwardedContinue(JStatement continueTo,
                                    CBodyContext from)
                             throws PositionedError
Adds a continue from within this context to the specified statement.
Overrides:
addForwardedContinue in class CAbstractBodyContext

clearBreakAndContinues

public void clearBreakAndContinues()
Clears the set of breaks from withing this context; this is used when a finally clause invalidates the breaks within a try or catch clause.
