Class LDIFDiff


  • @ThreadSafety(level=NOT_THREADSAFE)
    public final class LDIFDiff
    extends CommandLineTool
    This class provides a command-line tool that can be used to identify the differences between two LDIF files. The output will itself be an LDIF file that contains the add, delete, and modify operations that can be processed against the source LDIF file to result in the target LDIF file.

        @NotNull
        public static ResultCode main​(@Nullable
                                      java.io.OutputStream out,

                                      java.lang.String... args)
        Invokes this tool with the provided set of command-line arguments, using the given output and error streams.
        Parameters:
        out - The output stream to use for standard output. It may be null if standard output should be suppressed.
        err - The output stream to use for standard error. It may be null if standard error should be suppressed.
        args - The set of arguments provided to this tool. It may be empty but must not be null.
        Returns:
        A result code indicating the status of processing. Any result code other than ResultCode.SUCCESS should be considered an error.
      • getToolName

        @NotNull
        public java.lang.String getToolName()
        Retrieves the name of this tool. It should be the name of the command used to invoke this tool.
        Specified by:
        getToolName in class CommandLineTool
        Returns:
        The name for this tool.
      • getAdditionalDescriptionParagraphs

        @NotNull
        public java.util.List<java.lang.String> getAdditionalDescriptionParagraphs()
        Retrieves additional paragraphs that should be included in the description for this tool. If the tool description should include multiple paragraphs, then the CommandLineTool.getToolDescription() method should return the text of the first paragraph, and each item in the list returned by this method should be the text for each subsequent paragraph. If the tool description should only have a single paragraph, then this method may return null or an empty list.
        Overrides:
        getAdditionalDescriptionParagraphs in class CommandLineTool
        Returns:
        Additional paragraphs that should be included in the description for this tool, or null or an empty list if only a single description paragraph (whose text is returned by the getToolDescription method) is needed.
      • supportsInteractiveMode

        public boolean supportsInteractiveMode()
        Indicates whether this tool should provide support for an interactive mode, in which the tool offers a mode in which the arguments can be provided in a text-driven menu rather than requiring them to be given on the command line. If interactive mode is supported, it may be invoked using the "--interactive" argument. Alternately, if interactive mode is supported and CommandLineTool.defaultsToInteractiveMode() returns true, then interactive mode may be invoked by simply launching the tool without any arguments.
        Overrides:
        supportsInteractiveMode in class CommandLineTool
        Returns:
        true if this tool supports interactive mode, or false if not.
      • supportsPropertiesFile

        public boolean supportsPropertiesFile()
        Indicates whether this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line.
        Overrides:
        supportsPropertiesFile in class CommandLineTool
        Returns:
        true if this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line, or false if not.
      • getToolCompletionMessage

        @Nullable
        protected java.lang.String getToolCompletionMessage()
        Retrieves an optional message that may provide additional information about the way that the tool completed its processing. For example if the tool exited with an error message, it may be useful for this method to return that error message.

        The message returned by this method is intended for informational purposes and is not meant to be parsed or programmatically interpreted.
        Overrides:
        getToolCompletionMessage in class CommandLineTool
        Returns:
        An optional message that may provide additional information about the completion state for this tool, or null if no completion message is available.
      • addToolArguments

        public void addToolArguments​(@NotNull
                                     ArgumentParser parser)
                              throws ArgumentException
        Adds the command-line arguments supported for use with this tool to the provided argument parser. The tool may need to retain references to the arguments (and/or the argument parser, if trailing arguments are allowed) to it in order to obtain their values for use in later processing.
        Specified by:
        addToolArguments in class CommandLineTool
        Parameters:
        parser - The argument parser to which the arguments are to be added.
        Throws:
        ArgumentException - If a problem occurs while adding any of the tool-specific arguments to the provided argument parser.
      • doExtendedArgumentValidation

        public void doExtendedArgumentValidation()
                                          throws ArgumentException
        Performs any necessary processing that should be done to ensure that the provided set of command-line arguments were valid. This method will be called after the basic argument parsing has been performed and immediately before the CommandLineTool.doToolProcessing() method is invoked. Note that if the tool supports interactive mode, then this method may be invoked multiple times to allow the user to interactively fix validation errors.
        Overrides:
        doExtendedArgumentValidation in class CommandLineTool
        Throws:
        ArgumentException - If there was a problem with the command-line arguments provided to this program.
      • getExampleUsages

        @NotNull
        public java.util.LinkedHashMap<java.lang.String[],​java.lang.String> getExampleUsages()
        Retrieves a set of information that may be used to generate example usage information. Each element in the returned map should consist of a map between an example set of arguments and a string that describes the behavior of the tool when invoked with that set of arguments.
        Overrides:
        getExampleUsages in class CommandLineTool
        Returns:
        A set of information that may be used to generate example usage information. It may be null or empty if no example usage information is available.
