- All Implemented Interfaces:
Accountable
- Enclosing class:
- STBlockLine
public static class STBlockLine.Serializer extends BlockLine.Serializer
Reads block lines encoded incrementally, with all fields corresponding to the term of the line.This class extends
BlockLine.Serializer
, so it keeps a state of the previous term read to decode the next term.
