Interface Result

public interface Result

The result of processing a GemFire Command Line Interface (CLI) command string. A string representation of this Result can be iterated over using the methods hasNextLine(), nextLine() and resetToFirstLine(). A Result may have one or more files as part of the command output and if so they can be saved to the file system using saveIncomingFiles(String). To check whether the result has a file in it use hasIncomingFiles().
