Constructor Detail

PRTokeniser

public PRTokeniser(RandomAccessFileOrArray file)
Creates a PRTokeniser for the specified RandomAccessFileOrArray. The beginning of the file is read to determine the location of the header, and the data source is adjusted as necessary to account for any junk that occurs in the byte source before the header

Parameters:
file - the source
