Method Detail

getPriority

public double getPriority()

The priority of the service. The usage of this service is twofold:

1. A service with a higher priority is more likely to be used if more than one service of the same type is registered.
2. A service with lower priority is instantiated and thereby executed earlier than other services of all types with higher priorities

Specified by:

getPriority in interface EMFFormsViewServiceFactory<T extends ViewModelService>

Returns:

The priority of this service

See Also:

EMFFormsViewServiceFactory.getPriority()

getType

public java.lang.Class<T> getType()

The type of the actual service provided by this provider.

Specified by:

getType in interface EMFFormsViewServiceFactory<T extends ViewModelService>

Returns:

The Class of the actual service

See Also:

EMFFormsViewServiceFactory.getType()

createService

public T createService(EMFFormsViewContext emfFormsViewContext)

Creates a new instance of the provided service.

Specified by:

createService in interface EMFFormsViewServiceFactory<T extends ViewModelService>

Parameters:

emfFormsViewContext - The EMFFormsViewContext to use during the creation of the service

Returns:

A new instance of the provided service or null if the service should not be created
