Class NoDupeAddLinesDecorator Decorator for a VersionedFiles that skips doing an add_lines if the key
Function network_bytes_to_kind_and_offset Strip of a record kind from the front of network_bytes.
Class NetworkRecordStream A record_stream which reconstitures a serialised stream.
Function fulltext_network_to_record Convert a network fulltext record to record.
Function record_to_fulltext_bytes Undocumented

def filter_absent(record_stream):
Adapt a record stream to remove absent records.
def make_versioned_files_factory(versioned_file_factory, mapper):
Create a ThunkedVersionedFiles factory.

This will create a callable which when called creates a ThunkedVersionedFiles on a transport, using mapper to access individual versioned files, and versioned_file_factory to create each individual file.

def network_bytes_to_kind_and_offset(network_bytes):
Strip of a record kind from the front of network_bytes.
Parametersnetwork_bytesThe bytes of a record.
ReturnsA tuple (storage_kind, offset_of_remaining_bytes)
def fulltext_network_to_record(kind, bytes, line_end):
Convert a network fulltext record to record.
def _length_prefix(bytes):
Undocumented
def record_to_fulltext_bytes(record):
Undocumented
def sort_groupcompress(parent_map):
