All Known Implementing Classes:
StateObjectFactory.StateObjectFactoryProxy
public interface StateObjectFactory
A factory for states and their component objects.

This interface is not intended to be implemented by clients.

Since:
3.1
Restriction:
This interface is not intended to be implemented by clients.

  • Field Details

    • defaultFactory

      static final StateObjectFactory defaultFactory
      The default object factory that can be used to create, populate and resolve states. This is particularly useful when using the resolver outside the context of a running Equinox framework.

  • Method Details

    • createState

      State createState()
      Deprecated.
      use createState(boolean)
      Creates an empty state. The returned state does not have an attached resolver.
      Returns:
      the created state

    • createState

      State createState(boolean resolver)
      Creates an empty state with or without a resolver.
      Parameters:
      resolver - true if the created state should be initialized with a resolver.
      Returns:
      the created state
      Since:
      3.2

    • createState

      State createState(State state)
      Creates a new state that is a copy of the given state. The returned state will contain copies of all bundle descriptions in the given state. The user objects from the original bundle descriptions is not copied and no data pertaining to resolution is copied. The returned state will have a new resolver attached to it.
      Parameters:
      state - a state to be copied
      Returns:
      the created state
