Detailed Description

This class can be used to efficiently search for occurrences of strings in a given string.

Theoretically speaking, a finite deterministic automaton is constructed which exactly accepts the strings that are to be recognized. In order to check whether a given string contains one of the strings that are being searched for the constructed automaton has to applied on each position in the given string.

findPrefix() [1/2]

QString KatePrefixStore::findPrefix	(	const Kate::TextLine &	line,
		int	start = 0
	)		const

Returns the shortest prefix of the given string that is contained in this prefix store starting at position 'start'.

findPrefix() [2/2]

QString KatePrefixStore::findPrefix	(	const QString &	s,
		int	start = 0
	)		const

Returns the shortest prefix of the given string that is contained in this prefix store starting at position 'start'.
