Constructor Detail

FactoryDescriptorsImpl

public FactoryDescriptorsImpl(Descriptor asService,
                              Descriptor asProvideMethod)

This creates a descriptor pair describing a Factory and the associated Factory.provide() method

Parameters:

asService - A description of the factory itself as an hk2 service. May not be null. Must have DescriptorType of DescriptorType.CLASS. One of the contracts must be Factory

asProvideMethod - A description of the provide method of the factory. Must have DescriptorType of DescriptorType.PROVIDE_METHOD. May not be null

Throws:

IllegalArgumentException - if the descriptors are not of the proper type

Method Detail

getFactoryAsAService

public Descriptor getFactoryAsAService()

Description copied from interface: FactoryDescriptors

This returns the factory as a service itself. The advertised contracts must contain the implementation class of the factory and the Factory. The descriptor type must be DescriptorType.CLASS since this descriptor is describing the factory itself.

Specified by:

getFactoryAsAService in interface FactoryDescriptors

Returns:

The factory as a service itself

getFactoryAsAFactory

public Descriptor getFactoryAsAFactory()

Description copied from interface: FactoryDescriptors

This returns the factory as a factory for some other type. The implementation class should contain the implementation class of the factory service. If the implementation class returned from this does not match the implementation class returned from getFactoryAsAService an error will occur. The contracts, name and qualifiers should represent the type returned from the provide method of the factory. The descriptor type must be DescriptorType.PROVIDE_METHOD since this descriptor is describing the factory as a factory, not as a service.

Specified by:

getFactoryAsAFactory in interface FactoryDescriptors

Returns:

The factory descriptor as a factory
