Direct Known Subclasses:

NotLikeFilter

public class LikeFilter<T>
extends RegexFilter<T>
implements SqlFilterSupport

A filter implements filtering a string based the LIKE condition as in SQL. The pattern is specified in the constructor. The patterns that you can choose from are: '%' allows you to match any string of any length (including zero length) and '_' allows you to match on a single character.

Please note, in Oracle, the SQL supports defining escape character but this is not supported in this LikeFilter. However if you need, you can override convertFromPatternToRegex to convert your own regular expression based on the input pattern.
