Nested Classes

Modifier and Type	Class and Description
class	SyncProtocol.SyncBulkResponse
class	SyncProtocol.SyncLineResponse
class	SyncProtocol.SyncMultiBulkResponse
class	SyncProtocol.SyncMultiLineResponseBase Abstract base for all multiline responses (as of now, Bulk and MultBulk).
class	SyncProtocol.SyncResponseBase Synchronous responses are guaranteed to be contiguous chunks (if the client of this class is respecting its contract) -- meaning, it can go ahead and read as much as it can in its first read without busy waiting or reading one byte at a time.
