Method Details

decode

public void decode(Reader inputStream,
 DomGraph graph,
 NodeLabels labels)
            throws IOException,
ParserException,
MalformedDomgraphException

Description copied from class: InputCodec

Reads an USR representation from a Reader. This method converts the USR into an equivalent labelled dominance graph and stores this graph in a DomGraph and the labels in a NodeLabels object. You must implement this method in every concrete input codec.

The graph and labels objects passed to this method need not be empty; it is the responsibility of this method to clear them first.

Specified by:

decode in class InputCodec

Parameters:

inputStream - the reader from which the USR is read

graph - the dominance graph into which the USR is converted

labels - the node labels of the labelled dominance graph

Throws:

IOException - if an I/O error occurred while reading from reader

ParserException - if a syntactic error occurred while parsing the USR

MalformedDomgraphException - if a semantic error occurred, i.e. the USR cannot be converted into a dominance graph
