Constructor Detail

UDTCodecImpl

public UDTCodecImpl(UDTClassInfoImpl<T> cinfo,
                    String keyspace)

Instantiates a new default UDTCodecImpl object.

Parameters:

cinfo - the udt class info

keyspace - the keyspace for which to create a codec

UDTCodecImpl

public UDTCodecImpl(UDTClassInfoImpl<T> cinfo,
                    com.datastax.driver.core.UserType definition)

Instantiates a new UDTCodecImpl object.

Parameters:

cinfo - the udt class info

definition - the registered user type definition to use when decoding

Method Detail

getUserType

protected com.datastax.driver.core.UserType getUserType()

Gets the user type for this codec.

Returns:

the user type for this codec

register

protected void register(com.datastax.driver.core.UserType definition)

Registers a new cluster-defined definition for the user type being decoded by this codec.

Parameters:

definition - the new definition for the user type to register

Throws:

IllegalArgumentException - if the definition doesn't correspond to this one

deregister

protected void deregister(com.datastax.driver.core.UserType definition)

Deregisters the current definition from this codec as it was removed from the cluster.

Parameters:

definition - the definition for the user type to deregister

Throws:

IllegalArgumentException - if the definition doesn't correspond to this one
