Class Base64Tool

java.lang.Object

com.unboundid.util.CommandLineTool

com.unboundid.ldap.sdk.examples.Base64Tool

@ThreadSafety(level=NOT_THREADSAFE)
public final class Base64Tool
extends CommandLineTool

This class provides a tool that can be used to perform base64 encoding and decoding from the command line. It provides two subcommands: encode and decode. Each of those subcommands offers the following arguments:

• "--data {data}" -- specifies the data to be encoded or decoded.
• "--inputFile {data}" -- specifies the path to a file containing the data to be encoded or decoded.
• "--outputFile {data}" -- specifies the path to a file to which the encoded or decoded data should be written.

The "--data" and "--inputFile" arguments are mutually exclusive, and if neither is provided, the data to encode will be read from standard input. If the "--outputFile" argument is not provided, then the result will be written to standard output.

                  @Nullable
                  java.io.OutputStream err)

Creates a new instance of this tool with the provided information. Standard input will not be available.

Parameters:

out - The output stream to which standard out should be written. It may be null if standard output should be suppressed.

err - The output stream to which standard error should be written. It may be null if standard error should be suppressed.

                  @Nullable
                  java.io.OutputStream err)

Creates a new instance of this tool with the provided information.

Parameters:

in - The input stream to use for standard input. It may be null if no standard input is needed.

out - The output stream to which standard out should be written. It may be null if standard output should be suppressed.

err - The output stream to which standard error should be written. It may be null if standard error should be suppressed.

Method Detail

main

public static void main(@NotNull
                        java.lang.String... args)

Runs the tool with the provided set of arguments.

Parameters:

args - The command line arguments provided to this program.

main

@NotNull
public static ResultCode main(@Nullable
                                       java.io.InputStream in,
                                       @Nullable
                                       java.io.OutputStream out,
                                       @Nullable
                                       java.io.OutputStream err,
                                       @NotNull
                                       java.lang.String... args)

Runs the tool with the provided information.

Parameters:

in - The input stream to use for standard input. It may be null if no standard input is needed.

out - The output stream to which standard out should be written. It may be null if standard output should be suppressed.

err - The output stream to which standard error should be written. It may be null if standard error should be suppressed.

args - The command line arguments provided to this program.

Returns:

The result code obtained from running the tool. A result code other than ResultCode.SUCCESS will indicate that an error occurred.

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.

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 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 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.

supportsOutputFile

protected boolean supportsOutputFile()

Indicates whether this tool should provide arguments for redirecting output to a file. If this method returns true, then the tool will offer an "--outputFile" argument that will specify the path to a file to which all standard output and standard error content will be written, and it will also offer a "--teeToStandardOut" argument that can only be used if the "--outputFile" argument is present and will cause all output to be written to both the specified output file and to standard output.

Overrides:

supportsOutputFile in class CommandLineTool

Returns:

true if this tool should provide arguments for redirecting output to a 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.

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.
