activemq-flow: ISourceController and ISinkController interfaces should be
updated to take use <?> Generics for increased flexibility
------------------------------------------------------------------------------------------------------------------------------------
Key: AMQ-2165
URL: https://issues.apache.org/activemq/browse/AMQ-2165
Project: ActiveMQ
Issue Type: Improvement
Affects Versions: incubation
Environment: N/A
Reporter: Colin MacNaughton
Priority: Minor
Fix For: incubation
ISinkController and ISourceController's should pass wildcard generic versions
of themselves to one another to increase flexibility of passing elements of
common base types to one another:
ISinkController<E> should use:
public void add(E elem, ISourceController<?> controller); //instead of: public
void add(E elem, ISourceController<E> controller);
public void offer(E elem, ISourceController<?> controller); //instead of
public void offer(E elem, ISourceController<E> controller);
and ISinkController<E> should use:
public void onFlowBlock(ISinkController<?> controller); //instead of public
void onFlowBlock(ISinkController<E> controller)
public void onFlowResume(ISinkController<?> controller); //instead of public
void onFlowResume(ISinkController<E> controller); //instead of
This allows for type conversions of elements between flow controllers.
