public abstract class BooleanBuiltin
extends AbstractBuiltin

Base class of all boolean built-in predicates. This kind of built-in ... a) can have any arity b) can only be evaluated when all the terms are known (i.e. no unknown variables) c) evaluates to true or false

Constructor Detail

BooleanBuiltin

public BooleanBuiltin(IPredicate predicate,
                      ITerm... terms)

Constructor.

Parameters:

predicate - The predicate for this built-in.

terms - The collection of terms, must be length 2 for comparisons.

Method Detail

evaluateTerms

protected ITerm evaluateTerms(ITerm[] terms,
                              int[] variableIndexes)

Description copied from class: AbstractBuiltin

Evaluate the predicate once the terms and variable indexes have been found.

Overrides:

evaluateTerms in class AbstractBuiltin

Parameters:

terms - The array of all terms for this evaluation.

variableIndexes - the indexes of the terms which should be computed (starting at 0)

Returns:

The result of the evaluation.

computeResult

protected abstract boolean computeResult(ITerm[] terms)

Compute the result of the comparison.

Parameters:

terms - The terms

Returns:

The result of the comparison.
