Enclosing class:
DictionaryBasedBreakIterator

protected class DictionaryBasedBreakIterator.Builder
extends RuleBasedBreakIterator_Old.Builder

The Builder class for DictionaryBasedBreakIterator inherits almost all of its functionality from the Builder class for RuleBasedBreakIterator_Old, but extends it with extra logic to handle the DICTIONARY_VAR token

Method Detail

handleSpecialSubstitution

protected void handleSpecialSubstitution(String replace,
                                         String replaceWith,
                                         int startPos,
                                         String description)
We override handleSpecialSubstitution() to add logic to handle the $dictionary tag. If we see a substitution named DICTIONARY_VAR, parse the substitution expression and store the result in dictionaryChars.

Overrides:
handleSpecialSubstitution in class RuleBasedBreakIterator_Old.Builder

buildCharCategories

protected void buildCharCategories(Vector tempRuleList)
The other half of the logic to handle the dictionary characters happens here. After the inherited builder has derived the real character categories, we set up the categoryFlags array in the iterator. This array contains "true" for every character category that includes a dictionary character.

Overrides:
buildCharCategories in class RuleBasedBreakIterator_Old.Builder

mungeExpressionList

protected void mungeExpressionList(Hashtable expressions)
Overrides:
mungeExpressionList in class RuleBasedBreakIterator_Old.Builder
