Method Detail

execute

public void execute(String[] args)

Process command line options and run generator.

If no options are passed, prints the help. Help is also printed if the command line options are invalid.

Parameters:

args - generator options

generate

public abstract void generate(Properties configProps,
                              File cobolFile,
                              String cobolFileEncoding,
                              File output,
                              String packageNamePrefix,
                              String xsltFileName)

createOptions

protected org.apache.commons.cli.Options createOptions()

Returns:

the command line options

collectOptions

protected boolean collectOptions(org.apache.commons.cli.Options options,
                                 String[] args)

Take arguments received on the command line and setup corresponding options.

setOutput

public void setOutput(String outputPath)

Check the output parameter and keep it only if it is valid.

Parameters:

outputPath - a file or folder name (relative or absolute)

setOutputPackagePrefix

public void setOutputPackagePrefix(String packagePrefix)

Check that package prefix name provided is valid.
