Package jnr.posix

Interface POSIXHandler

All Known Implementing Classes:
DefaultPOSIXHandler

public interface POSIXHandler
The POSIXHandler class allows you do implement the runtime-specific behavior you need in such a way that it is insulated from the implementation of the POSIX library. Implementing each of the methods in this interface should give you are working POSIX implementation.
  • Method Details

    • error

      void error(jnr.constants.platform.Errno error, String extraData)
    • error

      void error(jnr.constants.platform.Errno error, String methodName, String extraData)
    • unimplementedError

      void unimplementedError(String methodName)
      Specify that posix method is unimplemented. In JRuby we generate an exception with this.
      Parameters:
      methodName - the POSIX method that failed
    • warn

      void warn(POSIXHandler.WARNING_ID id, String message, Object... data)
    • isVerbose

      boolean isVerbose()
      Returns:
      should we provide verbose output about POSIX activities
    • getCurrentWorkingDirectory

      File getCurrentWorkingDirectory()
      Returns:
      current working directory of your runtime.
    • getEnv

      String[] getEnv()
      Returns:
      current set of environment variables of your runtime.
    • getInputStream

      InputStream getInputStream()
      Returns:
      your runtime's current input stream
    • getOutputStream

      PrintStream getOutputStream()
      Returns:
      your runtime's current output stream
    • getPID

      int getPID()
      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 unimplementedError(String).
      Returns:
      your runtime's process ID
    • getErrorStream

      PrintStream getErrorStream()
      Get your runtime's current ErrorStream
      Returns:
      your runtime's current error stream
