-
- Enclosing class:
- TokenBuffer
protected static final class TokenBuffer.Segment extends java.lang.Object
Individual segment of TokenBuffer that can store up to 16 tokens (limited by 4 bits per token type marker requirement). Current implementation uses fixed length array; could alternatively use 16 distinct fields and switch statement (slightly more efficient storage, slightly slower access)
