Interface | Description |
---|---|
GatewayServerListener |
A client can implement this listener to be notified of Gateway events.
|
Py4JClientConnection | |
Py4JJavaServer |
Interface that describes the operations a server must support to receive
requests from the Python side.
|
Py4JPythonClient |
Interface that describes the operations a client must support to make
requests to the Python side.

Class | Description |
---|---|
BufferGatewayTest | |
CallbackClient |
A CallbackClient is responsible for managing communication channels: channels
are created as needed (e.g., one per concurrent thread) and are closed after
a certain time.
|
CallbackConnection |
Default implementation of the CommunicationChannel interface using TCP
sockets.
|
ClientServer |
This class creates the JavaServer and the PythonClient necessary to
communicate with a Python virtual machine with the new threading model.
|
ClientServer.ClientServerBuilder |
Helper class to make it easier and self-documenting how a
ClientServer is constructed. |
ClientServerConnection | |
ClientServerTest | |
DefaultApplication |
Default application that can be used to quickly test Py4J.
|
DefaultGatewayServerListener |
This class implements a default
GatewayServerListener . |
EchoClient | |
EchoClientTest | |
EchoServer | |
EchoServerTest | |
Gateway |
A Gateway manages various states: entryPoint, references to objects returned
to a Python program, etc.
|
GatewayConnection |
Manage the connection between a Python program and a Gateway.
|
GatewayServer |
This class enables Python programs to access a Java program.
|
GatewayServer.GatewayServerBuilder |
Helper class to make it easier and self-documenting how a
GatewayServer is constructed. |
GatewayServerTest | |
GatewayTest | |
InstrGatewayTest | |
JavaServer |
This class extends GatewayServer by implementing a new threading model:
a thread always use the same connection to the other side so callbacks are
executed in the calling thread.
|
JVMView |
A JVM view keeps track of imports and import searches.
|
NetworkUtil |
Utility class used to perform network operations.
|
Protocol |
This class defines the protocol used to communicate between two virtual
machines (e.g., Python and Java).
|
ProtocolTest | |
ProxyTest | |
PythonClient |
Subclass of CallbackClient that implements the new threading model,
ensuring that each thread uses its own connection.
|
PythonTestClient | |
ReturnObject |
A ReturnObject wraps a value returned by a method.
|
StringUtil |
String utility class providing operations to escape and unescape new lines.
|
StringUtilTest |

---|---|
Py4JException |
Exception raised when an error is encountered while using Py4J.
|
Py4JJavaException |
Exception raised when an exception is thrown in the client code.
|
Py4JNetworkException |
Exception raised when a network error is encountered while using Py4J.
