  • Method Details

    • error

      public void error(jnr.constants.platform.Errno error, String extraData)
      Specified by:
      error in interface POSIXHandler

    • error

      public void error(jnr.constants.platform.Errno error, String methodName, String extraData)
      Specified by:
      error in interface POSIXHandler

    • unimplementedError

      public void unimplementedError(String methodName)
      Description copied from interface: POSIXHandler
      Specify that posix method is unimplemented. In JRuby we generate an exception with this.
      Specified by:
      unimplementedError in interface POSIXHandler
      Parameters:
      methodName - the POSIX method that failed

    • warn

      public void warn(POSIXHandler.WARNING_ID id, String message, Object... data)
      Specified by:
      warn in interface POSIXHandler

    • isVerbose

      public boolean isVerbose()
      Specified by:
      isVerbose in interface POSIXHandler
      Returns:
      should we provide verbose output about POSIX activities

    • getCurrentWorkingDirectory

      public File getCurrentWorkingDirectory()
      Specified by:
      getCurrentWorkingDirectory in interface POSIXHandler
      Returns:
      current working directory of your runtime.

    • getEnv

      public String[] getEnv()
      Specified by:
      getEnv in interface POSIXHandler
      Returns:
      current set of environment variables of your runtime.

    • getInputStream

      public InputStream getInputStream()
      Specified by:
      getInputStream in interface POSIXHandler
      Returns:
      your runtime's current input stream

    • getOutputStream

      public PrintStream getOutputStream()
      Specified by:
      getOutputStream in interface POSIXHandler
      Returns:
      your runtime's current output stream

    • getPID

      public int getPID()
      Description copied from interface: POSIXHandler
      Get your runtime's process ID. This is only intended for non-native POSIX support (e.g. environments where JNA cannot load or security restricted environments). In JRuby we found a number of packages which would rather have some identity for the runtime than nothing. Note: If you do not want this to work you impl can just call POSIXHandler.unimplementedError(String).
      Specified by:
      getPID in interface POSIXHandler
      Returns:
      your runtime's process ID

    • getErrorStream

      public PrintStream getErrorStream()
      Description copied from interface: POSIXHandler
      Get your runtime's current ErrorStream
      Specified by:
      getErrorStream in interface POSIXHandler
      Returns:
      your runtime's current error stream
