Method Detail

parse

public final int parse(InputStream stream,
                       RepInfo info,
                       int parseIndex)
                throws IOException

Parse the content of a stream digital object and store the results in RepInfo.

Specified by:

parse in interface Module

Overrides:

parse in class ModuleBase

Parameters:

stream - An InputStream, positioned at its beginning, which is generated from the object to be parsed. If multiple calls to parse are made on the basis of a nonzero value being returned, a new InputStream must be provided each time.

info - A fresh (on the first call) RepInfo object which will be modified to reflect the results of the parsing If multiple calls to parse are made on the basis of a nonzero value being returned, the same RepInfo object should be passed with each call.

parseIndex - Must be 0 in first call to parse. If parse returns a nonzero value, it must be called again with parseIndex equal to that return value.

Throws:

IOException

checkSignatures

public void checkSignatures(File file,
                            InputStream stream,
                            RepInfo info)
                     throws IOException

Check if the digital object conforms to this Module's internal signature information. Try to read the BOM if it's present, and check the beginning of the file.

Specified by:

checkSignatures in interface Module

Overrides:

checkSignatures in class ModuleBase

Parameters:

file - A File object for the object being parsed

stream - An InputStream, positioned at its beginning, which is generated from the object to be parsed

info - A fresh RepInfo object which will be modified to reflect the results of the test

Throws:

IOException

checkMark

protected boolean checkMark(int byt,
                            RepInfo info)
