Method Summary

Modifier and Type	Method and Description
boolean	areEqual(T1 object1, T2 object2) Are the given two objects considered equal?
default Predicate1<T2>	foldLeft(T1 object1) Get a predicate with a fix argument for the first object of the equality check.

Method Detail

areEqual

boolean areEqual(T1 object1,
                 T2 object2)

Are the given two objects considered equal?

Parameters:

object1 - first object

object2 - second object

Returns:

true if this matcher considers the two objects equal
false if this matcher considers them different

test

default boolean test(T1 t1,
                     T2 t2)

Specified by:

test in interface java.util.function.BiPredicate<T1,T2>

foldLeft

@NotNull
default Predicate1<T2> foldLeft(T1 object1)

Get a predicate with a fix argument for the first object of the equality check.

Parameters:

object1 - fix first object

Returns:

predicate checking an object for being the same as object1

foldRight

@NotNull
default Predicate1<T1> foldRight(T2 object2)

Get a predicate with a fix argument for the second object of the equality check.

Parameters:

object2 - fix second object argument

Returns:

predicate checking an object for being the same as object2
