This class is package private. It registers several standard variants with the system which are then accessed via their IDs.

| private char[] spec The encoded pattern specification. The pattern consists of zero or more forms. Each form consists of a prefix, suffix, radix, minimum digit count, and maximum digit count. These values are stored as a five character header. That is, their numeric values are cast to 16-bit characters and stored in the string. Following these five characters, the prefix characters, then suffix characters are stored. Each form thus takes n+5 characters, where n is the total length of the prefix and suffix. The end is marked by a header of length one consisting of the character END. | |

| public void addSourceTargetSet(UnicodeSet inputFilter, UnicodeSet sourceSet, UnicodeSet targetSet) Overrides com. Doc from com. Returns the set of all characters that may be generated as replacement text by this transliterator, filtered by BOTH the input filter, and the current getFilter(). SHOULD BE OVERRIDDEN BY SUBCLASSES. It is probably an error for any transliterator to NOT override this, but we can't force them to for backwards compatibility. Other methods vector through this. When gathering the information on source and target, the compound transliterator makes things complicated. For example, suppose we have: Global FILTER = [ax] a > b; :: NULL; b > c; x > d;While the filter just allows a and x, b is an intermediate result, which could produce c. So the source and target sets cannot be gathered independently. What we have to do is filter the sources for the first transliterator according to the global filter, intersect that transliterator's filter. Based on that we get the target. The next transliterator gets as a global filter (global + last target). And so on. There is another complication: Global FILTER = [ax] a >|b; b >c;Even though b would be filtered from the input, whenever we have a backup, it could be part of the input. So ideally we will change the global filter as we go.
