Class BuffReaderParseFactory

java.lang.Object

net.sf.flatpack.brparse.BuffReaderParseFactory

All Implemented Interfaces:

ParserFactory

public class BuffReaderParseFactory
extends Object
implements ParserFactory

Provides a PZParser which obtains records directly from a BufferedReader as an alternative to reading the entire file into memory. Database column mappings are not supported by this factory at the present time. This class is meant to mimic the LargeDataSet class of pre 3.0 versions, which did not support database mappings either. A RuntimeExcpetion will be thrown if trying to obtain a parser for a database map.
