org.codehaus.groovy.runtime
[Java] Class SocketGroovyMethods

java.lang.Object
  org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport
      org.codehaus.groovy.runtime.SocketGroovyMethods

public class SocketGroovyMethods
extends DefaultGroovyMethodsSupport

This class defines new groovy methods for Sockets which enhance JDK classes inside the Groovy environment.

NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

Method Summary
static Socket accept(ServerSocket serverSocket, Closure closure)

Accepts a connection and passes the resulting Socket to the closure which runs in a new Thread.
static Socket accept(ServerSocket serverSocket, boolean runInANewThread, Closure closure)

Accepts a connection and passes the resulting Socket to the closure which runs in a new Thread or the calling thread, as needed.
static Writer leftShift(Socket self, Object value)

Overloads the left shift operator to provide an append mechanism to add things to the output stream of a socket
static OutputStream leftShift(Socket self, byte[] value)

Overloads the left shift operator to provide an append mechanism to add bytes to the output stream of a socket
static Object withObjectStreams(Socket socket, Closure closure)

Creates an InputObjectStream and an OutputObjectStream from a Socket, and passes them to the closure.

static Object withStreams(Socket socket, Closure closure)

Passes the Socket's InputStream and OutputStream to the closure.

Method Detail

accept

public static Socket accept(ServerSocket serverSocket, Closure closure)
Accepts a connection and passes the resulting Socket to the closure which runs in a new Thread.
throws:
IOException if an IOException occurs.
Parameters:
serverSocket - a ServerSocket
closure - a Closure
Returns:
a Socket
See Also:
ServerSocket.accept
Since:
1.0

accept

public static Socket accept(ServerSocket serverSocket, boolean runInANewThread, Closure closure)
Accepts a connection and passes the resulting Socket to the closure which runs in a new Thread or the calling thread, as needed.
throws:
IOException if an IOException occurs.
Parameters:
serverSocket - a ServerSocket
runInANewThread - This flag should be true, if the closure should be invoked in a new thread, else false.
closure - a Closure
Returns:
a Socket
See Also:
ServerSocket.accept
Since:
1.7.6

leftShift

public static Writer leftShift(Socket self, Object value)
Overloads the left shift operator to provide an append mechanism to add things to the output stream of a socket
throws:
IOException if an IOException occurs.
Parameters:
self - a Socket
value - a value to append
Returns:
a Writer
Since:
1.0

leftShift

public static OutputStream leftShift(Socket self, byte[] value)
Overloads the left shift operator to provide an append mechanism to add bytes to the output stream of a socket
throws:
IOException if an IOException occurs.
Parameters:
self - a Socket
value - a value to append
Returns:
an OutputStream
Since:
1.0

withObjectStreams

public static Object withObjectStreams(Socket socket, Closure closure)
Creates an InputObjectStream and an OutputObjectStream from a Socket, and passes them to the closure. The streams will be closed after the closure returns, even if an exception is thrown.
throws:
IOException if an IOException occurs.
Parameters:
socket - this Socket
closure - a Closure
Returns:
the value returned by the closure
Since:
1.5.0

withStreams

public static Object withStreams(Socket socket, Closure closure)
Passes the Socket's InputStream and OutputStream to the closure. The streams will be closed after the closure returns, even if an exception is thrown.
throws:
IOException if an IOException occurs.
Parameters:
socket - a Socket
closure - a Closure
Returns:
the value returned by the closure
Since:
1.5.2
