adding parameters to signal

[tom.baeyens]

in the next couple of posts, i'll be documenting some of the changes while i finalize the pvm api's.

the first one is adding parameters to a signal.

analogue to a method invocation on a java object, signals can have a named signal and parameters.

i opted for all method combinations on the execution:

void signal();
void signal(String signal);
void signal(Map<String, Object> parameters);
void signal(String signal, Map<String, Object> parameters);

That is because this is a user API and needs to be convenient.

Next I opted for a single signal method on the NodeBehaviour where the 'signal' and 'parameters' parameters can be null.

void signal(Execution execution, String signal, Map<String, Object> parameters);

Cause that is easier to implement. It's up to the execution implementation to provide the method delegations with the default null values.

all the changes will only be visible later this week when i commit. but i didn't want to wait to document them on the forum as i might forget to document them. i'll do another post on this forum to notify of commits.
