simpleMatch

public static boolean simpleMatch(String pattern,
 String str)

Match a String against the given pattern, supporting the following simple pattern styles: "xxx*", "*xxx", "*xxx*" and "xxx*yyy" matches (with an arbitrary number of pattern parts), as well as direct equality. Matching is case sensitive.

Parameters:

patterns - the patterns to match against

str - the String to match

Returns:

whether the String matches any of the given patterns

simpleMatch

public static boolean simpleMatch(List<String> patterns,
