Method Detail

getFoundLength

public int getFoundLength()

Description copied from interface: FinderFactory.StringFinder

Get the length of the found string. This is useful for regular expressions, because the length of the regular expression can be different than the length of the string that matched the expression.

Specified by:

getFoundLength in interface FinderFactory.StringFinder

reset

public void reset()

Description copied from class: FinderFactory.AbstractFinder

Reset the finder

Specified by:

reset in interface Finder

Overrides:

reset in class FinderFactory.AbstractFinder

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.
