  - 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
```
java.io.File getWorkingDirectory()
```
    Get the working directory of the created process.
    
    返回:
    
    the working directory
  - setWorkingDirectory
```
void setWorkingDirectory(java.io.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,
            java.io.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).
    
    java.io.IOException
  - execute
```
int execute(CommandLine command,
            java.util.Map environment)
     throws ExecuteException,
            java.io.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).
    
    java.io.IOException
  - execute
```
void execute(CommandLine command,
             ExecuteResultHandler handler)
      throws ExecuteException,
             java.io.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
    
    java.io.IOException
  - execute
```
void execute(CommandLine command,
             java.util.Map environment,
             ExecuteResultHandler handler)
      throws ExecuteException,
             java.io.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
    
    java.io.IOException
