Method Detail

newInstance

<RET> RET newInstance(String iClassName)

Creates a new entity instance. Each database implementation will return the right type.

Returns:

The new instance.

countClass

long countClass(String iClassName)

Counts the entities contained in the specified class and sub classes (polymorphic).

Parameters:

iClassName - Class name

Returns:

Total entities

countClass

long countClass(String iClassName,
                boolean iPolymorphic)

Counts the entities contained in the specified class.

Parameters:

iClassName - Class name

iPolymorphic - True if consider also the sub classes, otherwise false

Returns:

Total entities
