Class Param

org.fryske_akademy.jpa.Param

public class Param
extends Object

Nested Classes

Modifier and Type	Class	Description
static enum	Param.AndOr
static class	Param.Builder	A factory for Param objects, parameter values can be added in two ways: as (the correct) Object => only syntax and wildcard support for String values as a String optionally using a converter => syntax support also for non String values, no wildcard support when converter is used
