Class RuleBasedBreakIterator.DictionaryCache

java.lang.Object

com.ibm.icu.text.RuleBasedBreakIterator.DictionaryCache

Enclosing class:

RuleBasedBreakIterator

class RuleBasedBreakIterator.DictionaryCache
extends Object

DictionaryCache stores the boundaries obtained from a run of dictionary characters. Dictionary boundaries are moved first to this cache, then from here to the main BreakCache, where they may inter-leave with non-dictionary boundaries. The public BreakIterator API always fetches directly from the main BreakCache, not from here. In common situations, the number of boundaries in a single dictionary run should be quite small, it will be terminated by punctuation, spaces, or any other non-dictionary characters. The main BreakCache may end up with boundaries from multiple dictionary based runs. The boundaries are stored in a simple ArrayList (vector), with the assumption that they will be accessed sequentially.
