Member Function Documentation

EntityPtr DefinitionMaster::create ( const EntityHeader &  header )

overridevirtual

Constructs a MetaLog entity from an entity header.

When the MetaLog framework reads serialized entities from a MetaLog file, it first reads the entity header and passes that header into this method which will construct an empty entity. It then reconstructs the entity state by passing a pointer to the serialized entity to the Entity::decode() method.

Parameters

header

Entity header

Returns

Pointer to newly constructed entity, or 0 if entity described by header is no longer used

Implements Hypertable::MetaLog::Definition.

Definition at line 61 of file MetaLogDefinitionMaster.cc.

const char * DefinitionMaster::name ( )

overridevirtual

Returns MetaLog definition name.

This method returns the name of the MetaLog definition (e.g. "mml" or "rsml"). This name is used as the last path component of the directory name of the MetaLog. For example, the RSML for server "rs1" is stored in a directory path that looks something like /hypertable/servers/rs1/log/rsml.

Returns

MetaLog definition name

uint16_t DefinitionMaster::version ( )

overridevirtual

Returns version number of definition.

Returns

Version number of definition
