Class Match

  • public class Match
extends java.lang.Object
    Represents a match of a DittedBitSequence at a given offset in a byte sequence. There is a hidden assumption that the sequence is actually a Pattern that might have a ditted-bit-sequence, a set of match actions, and post match rules/checks

    • Constructor Detail

      • Match

        public Match​(DittedBitSequence sequence,
             long offset)
        Construct a Match of a DittedBitSequence at an offset within a byte stream. Object normally used when a match occurs during a MemoryBytePatternSearch.
        Parameters:
        sequence - that matched
        offset - from the start of byte stream where the matched occured

    • Method Detail

      • getNumPostBits

        public int getNumPostBits()
        If the sequence corresponds to a PatternPair, return the number of postbits
        Returns:
        the number of post bits

      • getMatchActions

        public MatchAction[] getMatchActions()
        Returns:
        actions associated with this match

      • getSequenceSize

        public int getSequenceSize()
        Returns:
        size in bytes of sequence

      • getSequenceIndex

        public int getSequenceIndex()
        Returns:
        index of sequence in a possibly longer set of sequences

      • getMarkOffset

        public long getMarkOffset()
        Returns:
        the offset of the match within a longer byte sequence

      • getMatchStart

        public long getMatchStart()
        Returns:
        offset of match in sequence of bytes

      • checkPostRules

        public boolean checkPostRules​(long streamoffset)
        Check that the possible post rules are satisfied
        Parameters:
        streamoffset - offset within from match location to check postrules.
        Returns:
        true if post rules are satisfied

      • getHexString

        public java.lang.String getHexString()
        Returns:
        ditted bit sequence as a string

      • getSequence

        public DittedBitSequence getSequence()
        Returns:
        the sequence that was matched
