Method Summary

Modifier and Type	Method and Description
UdtValue	externalToInternal(Map<EK,EV> external) Converts the external representation of a value (i.e., the value, as produced by a connector) to its internal representation (i.e., the Java type that matches the target CQL type).
Map<EK,EV>	internalToExternal(UdtValue internal) Converts the internal representation of a value (i.e., the Java type that matches the target CQL type) to its external representation (i.e., the value, as consumed by a connector).
