Annotation Type Accept

@Target(value=METHOD)
@Retention(value=RUNTIME)
public @interface Accept

This annotation is used to indicate that method is a filter method for a multi-fact inference method. The purpose of this annotation is similar to Override annotation, i.e. it ensures that accept methods are properly bound to rules container inference infrastructure. This annotation is checked at runtime after rule instantiation, as opposed to compile-time check of Override.

method

public abstract String method

Returns:

Inference method name, this accept method is for. If not specified, this accept method will be invoked for all infer methods with matching parameters.

Default:

""

parameterTypes

public abstract Class<?>[] parameterTypes

Returns:

Parameter types of inference method.

Default:

{}

parameterPositions

public abstract int[] parameterPositions

Returns:

Positions of parameters which this method is attached to. It is used for multi-parameter accept methods.

Default:

-1

cost

public abstract double cost

Cost of accept condition evaluation. This cost can be used by rule compilation/execution engine to optimize condition order.

Returns:

Default:

1.0
