scan

protected int scan(char ch,
                   boolean lastChar)

Description copied from class: FinderFactory.GenericBwdFinder

This function decides if it found a desired string or not. The function receives currently searched character and flag if it's the last one that is searched or not.

Specified by:

scan in class FinderFactory.GenericBwdFinder

Returns:

if the function decides that it found a desired string it sets found = true and returns how many characters back the searched string begins in backward direction (0 stands for current character). It is usually 0 as the finder usually decides after the last required character but it's not always the case e.g. for whole-words-only search it can be 1 or so. If the string is not yet found it returns how many characters it should go in backward direction (in this case it would usually be -1). The next searched character will be that one requested.
