Method Detail

bind0

public static <In0,In1> Predicate<In1> bind0(BinaryPredicate<In0,In1> binaryPredicate,
                                             In0 bindObject)

Transform binary predicates to unary predicates. Bind the element 0 to the given bindObject

bind1

public static <In0,In1> Predicate<In0> bind1(BinaryPredicate<In0,In1> binaryPredicate,
                                             In1 bindObject)

Transform binary predicates to unary predicates. Bind the element 1 to the given bindObject

calcIndex0ToPredicate

public static Predicate<java.lang.Integer> calcIndex0ToPredicate(CalcIndex0<java.lang.Boolean> calc)

Predicate and Calc has different signature this is an adapter method.
It creates a thin wrapper.

Predicate and Calc has different signature this is an adapter method.
It creates a thin wrapper.

Parameters:

calc -

Returns:

bind0
