Method Detail

addExtraOptions

protected void addExtraOptions(ArgOptions options)

Adds options to the provided ArgOptions instance, which will be used to parse the command line. This method allows subclasses the ability to add extra command line options.

Overrides:

addExtraOptions in class GenericMain

Parameters:

options - the ArgOptions object which more main specific options can be added to.

See Also:

GenericMain.handleExtraOptions()

getSpace

protected SemanticSpace getSpace()

Returns the SemanticSpace that will be used for processing. This method is guaranteed to be called after the command line arguments have been parsed, so the contents of GenericMain.argOptions are valid.

Specified by:

getSpace in class GenericMain

saveSSpace

protected void saveSSpace(SemanticSpace sspace,
              File outputFile)
                   throws IOException

Saves the BasisMapping created from the BasisMaker.OccurrenceCounter.

Overrides:

saveSSpace in class GenericMain

Throws:

IOException
