  • 方法详细资料

    • setExitValue

      void setExitValue(int value)
      Define the exitValue of the process to be considered successful. If a different exit value is returned by the process then execute(CommandLine) will throw an ExecuteException
      参数:
      value - the exit code representing successful execution

    • setExitValues

      void setExitValues(int[] values)
      Define a list of exitValue of the process to be considered successful. The caller can pass one of the following values
      • an array of exit values to be considered successful
      • an empty array for auto-detect of successful exit codes relying on isFailure(int)
      • null to indicate to skip checking of exit codes
      If an undefined exit value is returned by the process then execute(CommandLine) will throw an ExecuteException.
      参数:
      values - a list of the exit codes

    • isFailure

      boolean isFailure(int exitValue)
      Checks whether exitValue signals a failure. If no exit values are set than the default conventions of the OS is used. e.g. most OS regard an exit code of '0' as successful execution and everything else as failure.
      参数:
      exitValue - the exit value (return code) to be checked
      返回:
      true if exitValue signals a failure

    • getStreamHandler

      ExecuteStreamHandler getStreamHandler()
      Get the StreamHandler used for providing input and retrieving the output.
      返回:
      the StreamHandler

    • setStreamHandler

      void setStreamHandler(ExecuteStreamHandler streamHandler)
      Set a custom the StreamHandler used for providing input and retrieving the output. If you don't provide a proper stream handler the executed process might block when writing to stdout and/or stderr (see Process).
      参数:
      streamHandler - the stream handler

    • getWatchdog

      ExecuteWatchdog getWatchdog()
      Get the watchdog used to kill of processes running, typically, too long time.
      返回:
      the watchdog

    • setWatchdog

      void setWatchdog(ExecuteWatchdog watchDog)
      Set the watchdog used to kill of processes running, typically, too long time.
      参数:
      watchDog - the watchdog

    • getProcessDestroyer

      ProcessDestroyer getProcessDestroyer()
      Set the handler for cleanup of started processes if the main process is going to terminate.
      返回:
      the ProcessDestroyer

    • setProcessDestroyer

      void setProcessDestroyer(ProcessDestroyer processDestroyer)
      Get the handler for cleanup of started processes if the main process is going to terminate.
      参数:
      processDestroyer - the ProcessDestroyer

    • getWorkingDirectory

      File getWorkingDirectory()
      Get the working directory of the created process.
      返回:
      the working directory

    • setWorkingDirectory

      void setWorkingDirectory(File dir)
      Set the working directory of the created process. The working directory must exist when you start the process.
      参数:
      dir - the working directory

    • execute

      int execute(CommandLine command) throws ExecuteException, IOException
      Methods for starting synchronous execution. The child process inherits all environment variables of the parent process.
      参数:
      command - the command to execute
      返回:
      process exit value
      抛出:
      ExecuteException - execution of subprocess failed or the subprocess returned a exit value indicating a failure setExitValue(int).
      IOException

    • execute

      int execute(CommandLine command, Map environment) throws ExecuteException, IOException
      Methods for starting synchronous execution.
      参数:
      command - the command to execute
      environment - The environment for the new process. If null, the environment of the current process is used.
      返回:
      process exit value
      抛出:
      ExecuteException - execution of subprocess failed or the subprocess returned a exit value indicating a failure setExitValue(int).
      IOException

    • execute

      void execute(CommandLine command, ExecuteResultHandler handler) throws ExecuteException, IOException
      Methods for starting asynchronous execution. The child process inherits all environment variables of the parent process. Result provided to callback handler.
      参数:
      command - the command to execute
      handler - capture process termination and exit code
      抛出:
      ExecuteException - execution of subprocess failed
      IOException

    • execute

      void execute(CommandLine command, Map environment, ExecuteResultHandler handler) throws ExecuteException, IOException
      Methods for starting asynchronous execution. The child process inherits all environment variables of the parent process. Result provided to callback handler.
      参数:
      command - the command to execute
      environment - The environment for the new process. If null, the environment of the current process is used.
      handler - capture process termination and exit code
      抛出:
      ExecuteException - execution of subprocess failed
      IOException
