Method Detail

newInstance

public <POJO> POJO newInstance(Class<POJO> pojoType)
                 throws InstantiationFailedException

This method creates a new instance of the given pojoType.
The simplest implementation may just delegate to Class.newInstance(). However implementations can solve arbitrary problems such as if the given pojoType has no non-arg constructor, or it is an interface or abstract class.

Specified by:

newInstance in interface PojoFactory

Type Parameters:

POJO - is the generic type of the Pojo to create.

Parameters:

pojoType - is the Class reflecting the Pojo to create.

Returns:

the new instance of the given pojoType.

Throws:

InstantiationFailedException - if the instantiation failed.

newInstanceForClass

protected <POJO> POJO newInstanceForClass(Class<POJO> pojoType)
                            throws InstantiationFailedException

Implementation of newInstance(Class) for regular class.

Type Parameters:

POJO - is the generic type of the Pojo to create.

Parameters:

pojoType - is the Class reflecting the Pojo to create.

Returns:

the new instance of the given pojoType.

Throws:

InstantiationFailedException - if the instantiation failed.

newInstanceForInterface

protected <POJO> POJO newInstanceForInterface(Class<POJO> pojoInterface)
                                throws InstantiationFailedException

This method is invoked from newInstance(Class) if the given Class is an interface.

Type Parameters:

POJO - is the generic type of the Pojo to create.

Parameters:

pojoInterface - is the interface reflecting the Pojo to create.

Returns:

the new instance of the given pojoType or null if no implementation could be found.

Throws:

InstantiationFailedException - if the instantiation failed.
