Interface BreakOpportunityProducer

All Superinterfaces:

ClassificationProducer, Cloneable

All Known Implementing Classes:

LineBreakProducer, WordBreakProducer

public interface BreakOpportunityProducer
extends ClassificationProducer

Checks for break-opportunities. The break opportunity is always a break after the last codepoint, under the condition, that this codepoint does not belong to a grapheme cluster.

This means, if we test the sequence 'ab', we cannot be sure that the letter 'a' is breakable, unless we've seen 'b' and have verified that 'b' is no extension or formatting character.

To use this producer properly, make sure that no extension characters get fed into it.
