Class TokenBuffer.Segment

java.lang.Object

com.fasterxml.jackson.databind.util.TokenBuffer.Segment

Enclosing class:

TokenBuffer

protected static final class TokenBuffer.Segment
extends 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)
