Method Details

isDirty

boolean isDirty(Object oldValue,
 Object newValue)

Determines whether the newValue is dirty relative to the oldValue.

Parameters:

oldValue - Object referring to the previous value.

newValue - Object referring to the new value.

Returns:

a boolean value indicating whether the newValue is dirty relative to the oldValue.

andThen

@NonNull
default IsDirtyPredicate andThen(@Nullable
 IsDirtyPredicate other)

Composes 2 IsDirtyPredicate objects using the logical AND operator. The other IsDirtyPredicate is applied after this IsDirtyPredicate in the isDirty(Object, Object) comparison evaluation. This composition is null-safe and returns this IsDirtyPredicate if other is null.

Parameters:

other - IsDirtyPredicate composed with this IsDirtyPredicate.

Returns:

an IsDirtyPredicate composition consisting of this IsDirtyPredicate composed with the other IsDirtyPredicate using the logical AND operator. Returns this IsDirtyPredicate if other is null.

orThen

@NonNull
default IsDirtyPredicate orThen(@Nullable
 IsDirtyPredicate other)

Composes 2 IsDirtyPredicate objects using the logical OR operator. The other IsDirtyPredicate is applied after this IsDirtyPredicate in the isDirty(Object, Object) comparison evaluation. This composition is null-safe and returns this IsDirtyPredicate if other is null.

Parameters:

other - IsDirtyPredicate composed with this IsDirtyPredicate.

Returns:

an IsDirtyPredicate composition consisting of this IsDirtyPredicate composed with the other IsDirtyPredicate using the logical OR operator. Returns this IsDirtyPredicate if other is null.
