mapValues

public final <R> java.util.stream.Stream<R> mapValues(java.util.function.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.

forceRenderingWhenEmpty

protected void forceRenderingWhenEmpty()

Use with caution - this could cause the library to render invalid SQL like "where column in ()".

accept

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

Specified by:

accept in interface VisitableCondition<T>

renderCondition

public abstract java.lang.String renderCondition(java.lang.String columnName,
                                                 java.util.stream.Stream<java.lang.String> placeholders)
