Method Detail

createTypedArray

public static <X> X[] createTypedArray(java.lang.Class<X> elementClass,
                                       int length)

Creates a typed array, as opposed to a generic Object[] that holds the typed values

Parameters:

elementClass - The type of the array elements. See Class.getComponentType()

length - The length to which the array should be created. This is usually zero for Hibernate uses

loadByArrayParameter

Load one or more instances of a model part (an entity or collection) based on a SQL ARRAY parameter to specify the keys (as opposed to the more traditional SQL IN predicate approach).

Type Parameters:

R - The type of the model part to load

K - The type of the keys
