Constructor Detail

NotEqualBuiltin

protected NotEqualBuiltin(IPredicate predicate,
                          ITerm... terms)

Construct a new NotEqualBuiltin for the specific predicate and terms.

Parameters:

predicate - The predicate of the built-in.

terms - The terms.

Throws:

NullPointerException - If the predicate or one of the terms is null.

IllegalArgumentException - If the length of the terms and the arity of the predicate do not match.

NotEqualBuiltin

public NotEqualBuiltin(ITerm... terms)

Constructs a built-in. Two terms must be passed to the constructor, otherwise an exception will be thrown.

Parameters:

terms - the terms

Throws:

NullPointerException - If the predicate or one of the terms is null.

IllegalArgumentException - If the length of the terms and the arity of the predicate do not match.
