## net.sf.saxon
Class Transform

    java.lang.Object
      net.sf.saxon.Transform

Direct Known Subclasses:
  DOMTransform, JDOMTransform, Transform

    public class Transform

extends Object

This Transform class is the command-line entry point to the Saxon XSLT Processor.

It is possible to subclass this class to provide a customized command line interface. In writing such a subclass:

- The `main(java.lang.String[])` method should instantiate the class and call the `doTransform(java.lang.String[], java.lang.String)` method, passing the argument list. The argument list can be augmented or modified if required: for example, by adding a -config argument to cause the configuration to be initialized from a configuration file.
- The `setFactoryConfiguration(boolean, java.lang.String)` method can be implemented

  Method Detail

  ### main

      public static void main(String[] args)
                       throws Exception

    Main program, can be used directly from the command line.

    The format is:

    java net.sf.saxon.Transform [options] source-file style-file >output-file

    followed by any number of parameters in the form {keyword=value}... which can be referenced from within the stylesheet.

    This program applies the XSL style sheet in style-file to the source XML document in source-file.

    Parameters:
      `args` - List of arguments supplied on operating system command line
    Throws:
      `Exception` - Indicates that a compile-time or run-time error occurred

  ### setPermittedOptions

      public void setPermittedOptions(CommandLineOptions options)

    Set the options that are recognized on the command line. This method can be overridden in a subclass to define additional command line options.

    Parameters:
      `options` - the CommandLineOptions in which the recognized options are to be registered.

  ### doTransform

      public void doTransform(String[] args,
                              String command)

    Support method for main program. This support method can also be invoked from subclasses that support the same command line interface

    Parameters:
      `args` - the command-line arguments
      `command` - the form of the command as written by the user. Not used, retained for backwards compatibility

  ### initializeConfiguration

      protected void initializeConfiguration(Configuration config)

    Customisation hook called immediately after the Configuration object is instantiated. The intended purpose of this hook is to allow a subclass to supply an OEM license key programmatically, but it can also be used for other initialization of the Configuration. This method is called before analyzing the command line options, so configuration settings made at this stage may be overridden when the command line options are processed. However, if a configuration file is used, the settings defined in the configuration file will have been applied.

    Parameters:
      `config` - the Configuration object

  ### setFactoryConfiguration

      public void setFactoryConfiguration(boolean schemaAware,
                                          String className)
                                   throws LicenseException

    Customisation hook called immediately after the Configuration object is instantiated. This hook is retained for backwards compatibility but it is recommended to implement `initializeConfiguration(net.sf.saxon.Configuration)` in preference. This method is called after `initializeConfiguration(net.sf.saxon.Configuration)`, but only if the configuration was not created using a configuration file. The default implementation does nothing.

    Parameters:
      `schemaAware` - True if the transformation is to be schema-aware
      `className` - Always null.
    Throws:
      `LicenseException` - can be thrown if there is no valid license available

  ### applyLocalOptions

      protected void applyLocalOptions(CommandLineOptions options,
                                       Configuration config)

    Customisation hook: apply options defined locally in a subclass. This method allows a subclass to recognize and implement command line options that are not recognized by the superclass. To prevent Saxon rejecting such options as errors, the method `setPermittedOptions(net.sf.saxon.trans.CommandLineOptions)` must be overridden in the subclass to add details of options recognized in the subclass.

    Parameters:
      `options` - the CommandLineOptions. This will contain details of all the options that were specified on the command line. Those that are recognized by the standard Saxon command line interface will already have been processed; other options can now be processed by the subclass.
      `config` - the Saxon Configuration

  ### preprocess

      public List preprocess(List sources)
                      throws XPathException

    Preprocess the list of sources. This method exists so that it can be overridden in a subclass

    Parameters:
      `sources` - the list of Source objects
    Returns:
      a revised list of Source objects
    Throws:
      `XPathException`

  ### getConfiguration

      protected Configuration getConfiguration()

    Get the configuration.

    Returns:
      the Saxon configuration

  ### quit

      protected static void quit(String message,
                                 int code)

    Exit with a message

    Parameters:
      `message` - The message to be output
      `code` - The result code to be returned to the operating system shell

  ### newController

      protected Controller newController(Templates sheet,
                                         CommandLineOptions options,
                                         PrintStream traceDestination)
                                  throws TransformerException

    Create a new Controller. This method is protected so it can be overridden in a subclass, allowing additional options to be set on the Controller

    Parameters:
      `sheet` - The Templates object representing the compiled stylesheet
      `options` - The commmand line options
      `traceDestination` - destination for trace output
    Returns:
      the newly constructed Controller to be used for the transformation
    Throws:
      `TransformerException` - if any error occurs

  ### badUsage

      protected void badUsage(String message)

    Report incorrect usage of the command line, with a list of the options and arguments that are available

    Parameters:
      `message` - The error message
