Interface BinaryPredicate<T>

Type Parameters:

T - the type of the operands

All Superinterfaces:

BinaryFunction<T,java.lang.Boolean>

All Known Implementing Classes:

AbstractQuantityStatisticPredicate, IsEqualTo, IsNotEqualTo, QuantityGreaterPredicate, QuantityLessPredicate

public interface BinaryPredicate<T>
extends BinaryFunction<T,java.lang.Boolean>

Represents a predicate (boolean-valued function) of two arguments of the same type. This is a functional interface whose functional method is test(Object, Object).

Method Summary

Modifier and Type	Method and Description
default java.lang.Boolean	perform(T left, T right) Has to be implemented to perform the actual operation.
boolean	test(T left, T right) Evaluates the predicate (condition) on the given arguments.

Method Detail

test

boolean test(T left,
             T right)

Evaluates the predicate (condition) on the given arguments.

Parameters:

left - the left operator of the condition

right - the right operator of the condition

Returns:

true if the predicate is fulfilled, false otherwise.

perform

default java.lang.Boolean perform(T left,
                                  T right)

Description copied from interface: BinaryFunction

Has to be implemented to perform the actual operation. The order of operands might be important or not, depending, if the operation is commutative or not.

Specified by:

perform in interface BinaryFunction<T,java.lang.Boolean>

Parameters:

left - the left operand to be used in the operation

right - the right operand to be used in the operation

Returns:

the result of the operation
