Class FCGIConnectionPool

java.lang.Object
  php.java.bridge.http.FCGIConnectionPool

public class FCGIConnectionPool
extends java.lang.Object

A connection pool. Example:

ConnectionPool pool = new ConnectionPool("127.0.0.1", 8080, 20, 5000, new IOFactory());
ConnectionPool.Connection conn = pool.openConnection();
InputStream in = conn.getInputStream();
OutputStream out = conn.getOutputStream();
...
in.close();
out.close();
...
pool.destroy();


Instead of using delegation (decorator pattern), it is possible to pass a factory which may create custom In- and OutputStreams. Example:

new ConnectionPool(..., new IOFactory() {
public InputStream getInputStream() {
return new DefaultInputStream() {
...
}
}
}
