@ThreadSafety(level=NOT_THREADSAFE)
public final class TransformLDIF
extends CommandLineTool
implements LDIFReaderEntryTranslator

This class provides a command-line tool that can be used to apply a number of transformations to an LDIF file. The transformations that can be applied include:

• It can scramble the values of a specified set of attributes in a manner that attempts to preserve the syntax and consistently scrambles the same value to the same representation.
• It can strip a specified set of attributes out of entries.
• It can redact the values of a specified set of attributes, to indicate that the values are there but providing no information about what their values are.
• It can replace the values of a specified attribute with a given set of values.
• It can add an attribute with a given set of values to any entry that does not contain that attribute.
• It can replace the values of a specified attribute with a value that contains a sequentially-incrementing counter.
• It can strip entries matching a given base DN, scope, and filter out of the LDIF file.
• It can perform DN mapping, so that entries that exist below one base DN are moved below a different base DN.
• It can perform attribute mapping, to replace uses of one attribute name with another.

main

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

                                       java.lang.String... args)

Invokes this tool with the provided set of arguments.

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 command-line arguments provided to this program.

Returns:

A result code indicating whether processing completed successfully.

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.

getToolDescription

@NotNull
public java.lang.String getToolDescription()

Retrieves a human-readable description for this tool. If the description should include multiple paragraphs, then this method should return the text for the first paragraph, and the CommandLineTool.getAdditionalDescriptionParagraphs() method should be used to return the text for the subsequent paragraphs.

Specified by:

getToolDescription in class CommandLineTool

Returns:

A human-readable description for this tool.

getToolVersion

@NotNull
public java.lang.String getToolVersion()

Retrieves a version string for this tool, if available.

Overrides:

getToolVersion in class CommandLineTool

Returns:

A version string for this tool, or null if none is available.

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.

defaultsToInteractiveMode

public boolean defaultsToInteractiveMode()

Indicates whether this tool defaults to launching in interactive mode if the tool is invoked without any command-line arguments. This will only be used if CommandLineTool.supportsInteractiveMode() returns true.

Overrides:

defaultsToInteractiveMode in class CommandLineTool

Returns:

true if this tool defaults to using interactive mode if launched without any command-line arguments, 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.

supportsDebugLogging

protected boolean supportsDebugLogging()

Indicates whether this tool supports the ability to generate a debug log file. If this method returns true, then the tool will expose additional arguments that can control debug logging.

Overrides:

supportsDebugLogging in class CommandLineTool

Returns:

true if this tool supports the ability to generate a debug log file, or false if not.

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.

doToolProcessing

@NotNull
public ResultCode doToolProcessing()

Performs the core set of processing for this tool.

Specified by:

doToolProcessing in class CommandLineTool

Returns:

A result code that indicates whether the processing completed successfully.

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.

translate

@Nullable
public Entry translate(@NotNull
                                 Entry original,
                                 long firstLineNumber)
                          throws LDIFException

Applies some special transformation or filtering to the original Entry.

Specified by:

translate in interface LDIFReaderEntryTranslator

Parameters:

original - The original Entry that was read and parsed from the input file.

firstLineNumber - The first line number of the LDIF record corresponding to the read Entry. This is most useful when throwing an LDIFException.

Returns:

The Entry that should be returned in the call to LDIFReader.readEntry(). This can be the original parameter Entry, a newly constructed Entry, or null to signal that the provided Entry should be skipped.

Throws:

LDIFException - If there is an exception during processing. This exception will be re-thrown to the caller of readEntry.
