Field Details

INSTANCE

static final PersistenceStringlyTypeHandler INSTANCE

A pass through handler.

Method Details

appendPersistenceConstructTo

default void appendPersistenceConstructTo(StringBuilder sb, Consumer<StringBuilder> renderer)

Renders the construction of the type to the string builder as JPQL.next expression. This is used in the renderer of the constructor function and usually just renders the argument through, because it is assumed to be a string on the persistence side.

Parameters:

sb - The string builder into which to render

renderer - The consumer that renders the argument to a string builder

appendPersistenceDestructTo

default boolean appendPersistenceDestructTo(StringBuilder sb, Function<StringBuilder,Boolean> renderer)

Renders the destruction of the type to the string builder as JPQL.next expression. This is used in the renderer of the destructor function and usually just renders the argument through, because it is assumed to be a string on the persistence side.

Parameters:

sb - The string builder into which to render

renderer - The consumer that renders the argument to a string builder

Returns:

whether the rendered value is constant
