Description copied from class: ReasoningNodeBase

Processes inputs.

Specified by:

process in class ReasoningNodeBase<F>

inputs - Inputs.

properties - Properties.

context - Context.

processingPath - Processing path.

consumer - Input consumer.

Returns:

Collection of future results.

Throws:

Exception - If anything goes wrong.

onConclusion

protected void onConclusion(Object[] args,
                            F conclusion)

This method is invoked before conclusion is put to the knowledge base. Rule classes can override this method to augment conclusions, e.g. inject some properties.

Parameters:

conclusion -

handleException

protected boolean handleException(Object[] args,
                                  Exception e)
                           throws Exception

Handles method invocation exception. This implementation invokes ExceptionListener.onException() if exception listener is not null.

Parameters:

e - Exception.

Returns:

True if exception was handled.

Throws:

Exception
