- Enclosing class:
- DictionaryBasedBreakIterator
- protected class DictionaryBasedBreakIterator.Builder
- extends RuleBasedBreakIterator.Builder
The Builder class for DictionaryBasedBreakIterator inherits almost all of
its functionality from the Builder class for RuleBasedBreakIterator, but
extends it with extra logic to handle the DICTIIONARY_VAR token
Fields inherited from class com.ibm.text.RuleBasedBreakIterator.Builder |
ALL_FLAGS, categories, clearLoopingStates, decisionPointList, decisionPointStack, DONT_LOOP_FLAG, END_STATE_FLAG, expressions, ignoreChars, LOOKAHEAD_STATE_FLAG, loopingStates, mergeList, statesToBackfill, tempStateTable |
Method Summary |
protected void |
buildCharCategories(java.util.Vector tempRuleList)
The other half of the logic to handle the dictionary characters happens here. |
protected void |
handleSpecialSubstitution(java.lang.String replace,
java.lang.String replaceWith,
int startPos,
java.lang.String description)
We override handleSpecialSubstitution() to add logic to handle
the $dictionary tag. |

DictionaryBasedBreakIterator.Builder
public DictionaryBasedBreakIterator.Builder()
- No special initialization
handleSpecialSubstitution
protected void handleSpecialSubstitution(java.lang.String replace,
java.lang.String replaceWith,
int startPos,
java.lang.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.Builder
buildCharCategories
protected void buildCharCategories(java.util.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.Builder
mungeExpressionList
protected void mungeExpressionList(java.util.Hashtable expressions)
- Overrides:
mungeExpressionList
in class RuleBasedBreakIterator.Builder
