  - PiiLayerParser
    This class provides an interface for handling a data structure called a .
  - PiiLoadException
    Thrown when the loading of a plug-in fails.
  - PiiOneGroupFlowController
    A flow controller that synchronizes a group of sockets with the same group ID.
  - PiiOneInputFlowController
    A flow controller that does not handle synchronization between sibling sockets.
  - PiiOperationTest
    A class that makes it easier to write unit tests for operations.
  - PiiOutputSocket
    An output socket.
  - PiiProbeInput
    An input socket that works without a controlling operation.
  - PiiProxySocket
    An input-output socket.
  - PiiResourceConnector
    An interface for classes that connect resource instances together.
  - PiiSocket
    Socket is a connection point between operations.
  - PiiSocketState
    A structure that stores information about a socket's state at run time.
