public MappingManager(Session session)
MappingManager using the provided Session with default
MapperConfiguration.
Note that this constructor forces the initialization of the session (see
MappingManager(Session, ProtocolVersion) if that is a problem for you).session - the Session to use.public MappingManager(Session session, ProtocolVersion protocolVersion)
MappingManager using the provided Session with default
MapperConfiguration.
This constructor is only provided for backward compatibility: before 2.1.7, MappingManager could be
built from an uninitialized session; since 2.1.7, the mapper needs to know the active protocol version to
adapt its internal requests, so MappingManager(Session) will now initialize the session if needed.
If you rely on the session not being initialized, use this constructor and provide the version manually.session - the Session to use.protocolVersion - the protocol version that will be used with this session.public MappingManager(Session session, MappingConfiguration configuration)
MappingManager using the provided Session with custom configuration
to be inherited to each instantiated mapper.
Note that this constructor forces the initialization of the session (see
MappingManager(Session, ProtocolVersion) if that is a problem for you).session - the Session to use.configuration - the MapperConfiguration to use be used as default for instantiated mappers.public MappingManager(Session session, MappingConfiguration configuration, ProtocolVersion protocolVersion)
MappingManager using the provided Session with default

Session used by this manager.
Note that you can get obtain the Cluster object corresponding
to that session using getSession().getCluster().
It is inadvisable to close the returned Session while this manager and
its mappers are in use.public MappingConfiguration getConfiguration()
configuration used by this manager.configuration used by this manager.public <T> Mapper<T> mapper(Class<T> klass)
Mapper for the provided class (that must be annotated by a
Table annotation).
The MappingManager only ever keeps one Mapper for each class, and so calling this
method multiple times on the same class will always return the same object.
If the type of any field in the class is an UDT-annotated classes, a codec for that
class will automatically be created and registered with the underlying Cluster.
This works recursively with UDTs nested in other UDTs or in collections.T - the type of the class to map.klass - the (annotated) class for which to return the mapper.Mapper object for class klass.public <T> TypeCodec<T> udtCodec(Class<T> klass)
TypeCodec for the provided class (that must be annotated by
a UDT annotation).
This method also registers the codec against the underlying Cluster.
In addition, the codecs for any nested UDTs will also be created and registered.
You don't need to call this method explicitly if you already call mapper(Class)
for a class that references this UDT class (creating a mapper will automatically
process all UDTs that it uses).T - the type of the class to map.klass - the (annotated) class for which to return the codec.public <T> T createAccessor(Class<T> klass)
Accessor annotation).
The MappingManager only ever keep one Accessor for each class, and so calling this
method multiple time on the same class will always return the same object.T - the type of the accessor class.klass - the (annotated) class for which to create an accessor object.klass.Copyright © 2012–2018. All rights reserved.
