Method Detail

• skipSearch

  public static int skipSearch(byte[] pattern,
               boolean direction,
               byte[] buffer,
               int start,
               int end,
               short[] skip)

  Deprecated. 
  Search a byte sequence for a given pattern. The method uses the skip search algorithm. The search can be performed in forward or backward direction, i.e. beginning from the start or end of the byte sequence.

  Parameters:

  pattern - byte[]

  direction - true if forward, false if backward

  buffer - byte[] to search

  start - index to start search

  end - index to end search (end index is not within the search)

  skip - short[256] A skipArray generated from a call to generateSkipArray.

  Returns:

  index or -1 if not found

• getSkipArray

  public static short[] getSkipArray(byte[] pattern,
                     boolean direction)

  Deprecated. 
  skipArray Builds a skip array for this pattern and direction. The skipArray is used in the optimized skipSearch

  Parameters:

  pattern -

  direction -

  Returns:

  short[256]

• isEqual

  public static boolean isEqual(byte[] pattern,
                byte[] buffer,
                int start,
                int end)

  Deprecated. 
  isEqual

  Parameters:

  pattern -

  buffer -

  start - index

  end - index

  Returns:

  true if the bytes in buffer[start] equal pattern

• search

  public static int search(byte[] search,
           byte[] bytes,
           int start,
           int end,
           boolean direction)

  Deprecated. 
  search Look for the search bytes in the bytes array using a straight search. Use the skip search if the number of bytes to search is large or if this search is performed frequently.

  Parameters:

  search - byte[]

  bytes - byte[] to search

  start - starting index

  end - end index (exclusive

  direction - boolean (true indicates forward search, false is backwards search

  Returns:

  index or -1
