filter

public IsEqualToWhenPresent<T> filter(Predicate<? super T> predicate)

Description copied from interface: AbstractSingleValueCondition.Filterable

If renderable and the value matches the predicate, returns this condition. Else returns a condition that will not render.

Specified by:

filter in interface AbstractSingleValueCondition.Filterable<T>

Parameters:

predicate - predicate applied to the value, if renderable

Returns:

this condition if renderable and the value matches the predicate, otherwise a condition that will not render.

map

public <R> IsEqualToWhenPresent<R> map(Function<? super T, ? extends @Nullable R> mapper)

Description copied from interface: AbstractSingleValueCondition.Mappable

If renderable, apply the mapping to the value and return a new condition with the new value. Else return a condition that will not render (this).

Specified by:

map in interface AbstractSingleValueCondition.Mappable<T>

Type Parameters:

R - type of the new condition

Parameters:

mapper - a mapping function to apply to the value, if renderable

Returns:

a new condition with the result of applying the mapper to the value of this condition, if renderable, otherwise a condition that will not render.
