PrologTextLoader

public PrologTextLoader(PrologTextLoaderState prologTextLoaderState,
                        Term root)

PrologTextLoader

public PrologTextLoader(PrologTextLoaderState prologTextLoaderState,
                        Reader stream)

Parameters:

prologTextLoaderState -

stream - the input stream to read from.

PrologTextLoader

public PrologTextLoader(PrologTextLoaderState prologTextLoaderState,
                        Reader stream,
                        String streamName)

Method Detail

getCurrentFile

public String getCurrentFile()

getCurrentLine

public int getCurrentLine()

getCurrentColumn

public int getCurrentColumn()

getCurrentPartialLoaderError

public PrologTextLoaderError getCurrentPartialLoaderError()

Get a PrologTextLoaderError for the position the PrologTextLoader is at to use later if something goes wrong caused by an error here. The message is null. This is mainly intended for use during initialisation.

Returns:

a partially filled in PrologTextLoaderError (missing a message)
