Method Detail

addHandler

public void addHandler(Class<? extends Throwable> type,
                       Continuation k)

Handlers can be only added immediately after instantiation.

getExceptionHandler

public Continuation getExceptionHandler(Class<? extends Throwable> type)

Description copied from interface: Env

Finds the exception handler that catches a Throwable instance of this type.

Specified by:

getExceptionHandler in interface Env

Overrides:

getExceptionHandler in class ProxyEnv

Returns:

never null. Even if there's no user-specified exception handler, the default 'unhandled exception handler' must be returned.

getReturnAddress

public Continuation getReturnAddress()

Description copied from interface: Env

Where should the return statement return to?

Specified by:

getReturnAddress in interface Env

Overrides:

getReturnAddress in class ProxyEnv

getBreakAddress

public Continuation getBreakAddress(String label)

Description copied from interface: Env

If we see a break statement, where should we go?

Specified by:

getBreakAddress in interface Env

Overrides:

getBreakAddress in class ProxyEnv

Parameters:

label - Specifies the loop to break from. null for nearest loop.

Returns:

For semantically correct Groovy code, the return value is never null, because not having the matching label is a compile-time error.

getContinueAddress

public Continuation getContinueAddress(String label)

Description copied from interface: Env

If we see a continue statement, where should we go?

Specified by:

getContinueAddress in interface Env

Overrides:

getContinueAddress in class ProxyEnv

Parameters:

label - Specifies the loop to repeat. null for nearest loop.

Returns:

For semantically correct Groovy code, the return value is never null, because not having the matching label is a compile-time error.
