uk.gov.nationalarchives.droid.core.signature.droid6.InternalSignatureComparator
A binary signature which can match one or more file formats.
It is composed of a list of {@link ByteSequence} objects,which are like regular expressions that can match bytes.
A signature runs each ByteSequence against a target file, until one of them doesn't match, or all of them do.
It orders the ByteSequence objects to try to ensure optimal matching behaviour - e.g. the ones anchored to the start of the file are done before ones at the end of the file. @author Martin Waller @author Matt Palmer @version 6.0.0
