isEmpty

public boolean isEmpty()

Description copied from interface: RenderableCondition

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 RenderableCondition<T>

Returns:

true if the condition is empty.

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)

operator

public abstract String operator()

renderCondition

public FragmentAndParameters renderCondition(RenderingContext renderingContext,
 BindableColumn<T> leftColumn)

Description copied from interface: RenderableCondition

Render a condition - typically a condition in a WHERE clause.

A rendered condition includes an SQL fragment, and any associated parameters. For example, the isEqual condition should be rendered as "= ?" where "?" is a properly formatted parameter marker (the parameter marker can be computed from the RenderingContext). Note that a rendered condition should NOT include the left side of the phrase - that is rendered by the RenderableCondition.renderLeftColumn(RenderingContext, BindableColumn) method.

Specified by:

renderCondition in interface RenderableCondition<T>

Parameters:

renderingContext - the current rendering context

leftColumn - the column related to this condition in a where clause

Returns:

the rendered condition. Should NOT include the column.
