// The SearchObject class represents a char_samp (a word bitmap) that is
21
// being searched for characters (or recognizeable entities).
22
// This is an abstract class that all SearchObjects should inherit from
23
// A SearchObject class provides methods to:
24
// 1- Returns the count of segments
25
// 2- Recognize a segment range
26
// 3- Creates a CharSamp for a segment range
