parseInstance

public IProblem parseInstance(InputStream in)
                       throws ParseFormatException,
                              ContradictionException,
                              IOException

Description copied from class: Reader

Read a file from a stream. It is important to note that benchmarks are usually encoded in ASCII, not UTF8. As such, the only reasonable way to feed a solver from a stream is to use a stream.

Specified by:

parseInstance in class Reader

Parameters:

in - a stream containing the benchmark.

Returns:

the problem to solve (an ISolver in fact).

Throws:

ParseFormatException - if an error occurs during parsing.

ContradictionException - if the problem is found trivially inconsistent.

IOException - if an I/O error occurs.
