int [].public int[] compilePattern(String data)
Translate the given String into a int []
representing the pattern matchable by this class.
This function translates a String into an int array
converting the special '*' and '\' characters.
Here is how the conversion algorithm works:
When more than two '*' characters, not separated by another character,
are found their value is considered as '**' (MATCH_PATH).
The array is always terminated by a special value (MATCH_END).
All MATCH* values are less than zero, while normal characters are equal
or greater.
