Method Detail

mapValues

public final <R> Stream<R> mapValues(Function<T,R> mapper)

shouldRender

public boolean shouldRender()

Description copied from interface: VisitableCondition

Subclasses can override this to inform the renderer if the condition should not be included in the rendered SQL. For example, IsEqualWhenPresent will not render if the value is null.

Specified by:

shouldRender in interface VisitableCondition<T>

Returns:

true if the condition should render.

renderingSkipped

public void renderingSkipped()

Description copied from interface: VisitableCondition

This method will be called during rendering when VisitableCondition.shouldRender() returns false.

Specified by:

renderingSkipped in interface VisitableCondition<T>

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,
                                                                    BiFunction<Collection<T>,Callback,S> constructor,
                                                                    S self,
                                                                    Supplier<S> emptySupplier)

mapSupport

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

filter

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

If renderable, apply the predicate to each value in the list and return a new condition with the filtered values. Else returns a condition that will not render (this). If all values are filtered out of the value list, then the condition will not render.

Parameters:

predicate - predicate applied to the values, if renderable

Returns:

a new condition with filtered values if renderable, otherwise a condition that will not render.

renderCondition

                                       Stream<String> placeholders)
