  +--ninja.activeproxy.path.Connector

Direct Known Subclasses:

PipeConnector, TCPConnector

public abstract class Connector

extends java.lang.Object

implements ConnectorIF

Connector is the base abstract class that other connectors should inherit from. There are only two methods that connectors must implement: createReader() and createWriter().

Field Summary

private java.lang.Object	info
private Operator	operator
private java.lang.Object	pathID

Constructor Summary

Connector()
Constructs a connector with no operator or path ID specified.

Connector(Operator operator, java.lang.Object pathID)
Constructs a connector with the specified operator and path ID.

Method Summary

abstract void	createReader() Creates a reader for an operator.
abstract void	createWriter(java.lang.Object info) Creates a writer for an operator.
java.lang.Object	getCommunicationInfo() Returns the information object.
Operator	getOperator() Returns the operator for which this connector creates a reader/writer.
java.lang.Object	getPathID() Returns the path ID of the path that will go through the operator.
void	setCommunicationInfo(java.lang.Object info) Sets the information object necessary for the previous operator in the path to setup its writer.
void	setOperator(Operator operator) Sets the operator for which this connector creates a reader/writer.
void	setOperatorReader(java.io.InputStream obj) Sets the reader of the operator.
void	setOperatorWriter(java.io.OutputStream obj) Sets the writer of the operator.
void	setPathID(java.lang.Object pathID) Sets the path ID of the path that will go through the operator.
