Method Detail

acceptable

public boolean acceptable(Object o)

Description copied from interface: Reasoner

decides if the goal is suitable for being processed by this reasoner. This method should be fast; if there are doubts as to whether a goal is acceptable, and it looks like determining it might take some time, the method should return true and let the process method figure it out.

Example. Many reasoners only process literals with certain predicates and arity. These reasoners will use those criteria to determine acceptability, for example a reasoner dealing with equality could accept goals that are:

1. Literals,
2. have = as their relation predicate,
3. have exactly two arguments.

Specified by:

acceptable in interface Reasoner

Overrides:

acceptable in class SequentialDispatcher

Returns:

true if the goal is suitable for this reasoner, false otherwise.

getReasonerClass

public Class getReasonerClass()

Description copied from interface: Dispatcher

Returns the class of reasoners this dispatcher works with. Every reasoner you add to this dispatcher must be an instance of this class.

Specified by:

getReasonerClass in interface Dispatcher

Overrides:

getReasonerClass in class SequentialDispatcher

Returns:

the class of reasoners this dispatcher works with.
