Class 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.

    • withStreams

      public static <T> T withStreams​(java.net.Socket socket, Closure<T> closure) throws java.io.IOException
      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.
      Parameters:
      socket - a Socket
      closure - a Closure
      Returns:
      the value returned by the closure
      Throws:
      java.io.IOException - if an IOException occurs.
      Since:
      1.5.2
    • withObjectStreams

      public static <T> T withObjectStreams​(java.net.Socket socket, Closure<T> closure) throws java.io.IOException
      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.
      Parameters:
      socket - this Socket
      closure - a Closure
      Returns:
      the value returned by the closure
      Throws:
      java.io.IOException - if an IOException occurs.
      Since:
      1.5.0
    • leftShift

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

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

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

    • accept

      public static java.net.Socket accept​(java.net.ServerSocket serverSocket, boolean runInANewThread, Closure closure) throws java.io.IOException
      Accepts a connection and passes the resulting Socket to the closure which runs in a new Thread or the calling thread, as needed.
      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
      Throws:
      java.io.IOException - if an IOException occurs.
      Since:
      1.7.6
