public void addSourceTargetSet(UnicodeSet filter, UnicodeSet sourceSet, UnicodeSet targetSet) Overrides com.ibm.icu.text.Transliterator.addSourceTargetSet. Doc from com.ibm.icu.text.Transliterator.addSourceTargetSet. Deprecated This API is ICU internal only. 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. Parameters targetSet:UnicodeSet TODO Annotations @Deprecated @Override ICU Status Internal ICU component.

Field Detail

ruleSet	back to summary
public TransliterationRuleSet ruleSet Rule table. May be empty.

variableNames	back to summary
pack-priv Map<String, char[]> variableNames Map variable name (String) to variable (char[]). A variable name corresponds to zero or more characters, stored in a char[] array in this hash. One or more of these chars may also correspond to a UnicodeSet, in which case the character in the char[] in this hash is a stand-in: it is an index for a secondary lookup in data.variables. The stand-in also represents the UnicodeSet in the stored rules.

variables	back to summary
pack-priv Object[] variables Map category variable (Character) to UnicodeMatcher or UnicodeReplacer. Variables that correspond to a set of characters are mapped from variable name to a stand-in character in data.variableNames. The stand-in then serves as a key in this hash to lookup the actual UnicodeSet object. In addition, the stand-in is stored in the rule text to represent the set of characters. variables[i] represents character (variablesBase + i).

variablesBase	back to summary
pack-priv char variablesBase The character that represents variables[0]. Characters variablesBase through variablesBase + variables.length - 1 represent UnicodeSet objects.
