Method Details

values

public final Stream<T> values()

isEmpty

public boolean isEmpty()

Description copied from interface: VisitableCondition

Subclasses can override this to indicate whether the condition is considered empty. This is primarily used in map and filter operations - the map and filter functions will not be applied if the condition is empty.

Specified by:

isEmpty in interface VisitableCondition<T>

Returns:

true if the condition is empty.

accept

public <R> R accept(ConditionVisitor<T,R> visitor)

Specified by:

accept in interface VisitableCondition<T>

filterSupport

protected <S extends AbstractListValueCondition<T>>
S filterSupport(Predicate<? super T> predicate,
 Function<Collection<T>,S> constructor,
 S self,
 Supplier<S> emptySupplier)

mapSupport

protected <R,
S extends AbstractListValueCondition<R>>
S mapSupport(Function<? super T,? extends R> mapper,
 Function<Collection<R>,S> constructor,
 Supplier<S> emptySupplier)

filter

public abstract AbstractListValueCondition<T> filter(Predicate<? super T> predicate)

If not empty, apply the predicate to each value in the list and return a new condition with the filtered values. Else returns an empty condition (this).

Parameters:

predicate - predicate applied to the values, if not empty

Returns:

a new condition with filtered values if renderable, otherwise an empty condition

operator

public abstract String operator()
