This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to a map of the specified types.
If the type of the keys and/or values is generic, use GettableByIndexData.getMap(int, TypeToken,
TypeToken).
Implementation note: the actual Map implementation will depend on the codec being used; therefore, callers should make no assumptions concerning its
mutability nor its thread-safety. Furthermore, the behavior of this method in respect to CQL
NULL values is also codec-dependent. By default, the driver will return mutable
instances, and a CQL NULL will mapped to an empty collection (note that Cassandra makes
no distinction between NULL and an empty collection).
getMap in interface GettableByIndexDatai - the index (0 <= i < size()) to retrieve.keysClass - the class for the keys of the map to retrieve.valuesClass - the class for the values of the map to retrieve.ith element as a map of K to V objects.public <K,V> Map<K,V> getMap(int i, TypeToken<K> keysType, TypeToken<V> valuesType)
ith value as a map.
This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to a map of the specified types.
Use this variant with nested collections, which produce a generic element type:
Map<Int, List<String>> l = row.getMap(1, TypeToken.of(Integer.class), new TypeToken<List<String>>() {});
Implementation note: the actual Map implementation will depend on the codec being used; therefore, callers should make no assumptions concerning its
mutability nor its thread-safety. Furthermore, the behavior of this method in respect to CQL
NULL values is also codec-dependent. By default, the driver will return mutable

ith value as a UDT value.
This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to a UDTValue (if the CQL type is a UDT, the registry will generate a codec
automatically).
getUDTValue in interface GettableByIndexDatai - the index (0 <= i < size()) to retrieve.ith element as a UDT value. If the value is NULL, then null will be returned.public TupleValue getTupleValue(int i)
ith value as a tuple value.
This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to a TupleValue (if the CQL type is a tuple, the registry will generate a codec
automatically).
getTupleValue in interface GettableByIndexDatai - the index (0 <= i < size()) to retrieve.ith element as a tuple value. If the value is NULL, then
null will be returned.public Object getObject(int i)
ith value as the Java type matching its CQL type.
This method uses the CodecRegistry to find the first codec that handles the
underlying CQL type. The Java type of the returned object will be determined by the codec that
was selected.
Use this method to dynamically inspect elements when types aren't known in advance, for
instance if you're writing a generic row logger. If you know the target Java type, it is
generally preferable to use typed getters, such as the ones for built-in types (GettableByIndexData.getBool(int), GettableByIndexData.getInt(int), etc.), or GettableByIndexData.get(int, Class) and GettableByIndexData.get(int,
TypeToken) for custom types.
getObject in interface GettableByIndexDatai - the index to retrieve.ith value as the Java type matching its CQL type.CodecRegistry.codecFor(DataType)public <T> T get(int i,
Class<T> targetClass)
GettableByIndexDataith value converted to the given Java type.
This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to the given Java type.
If the target type is generic, use GettableByIndexData.get(int, TypeToken).
Implementation note: the actual object returned by this method will depend on the codec being used; therefore, callers should make no assumptions concerning its
mutability nor its thread-safety. Furthermore, the behavior of this method in respect to CQL
NULL values is also codec-dependent; by default, a CQL NULL value translates to
null for simple CQL types, UDTs and tuples, and to empty collections for all CQL
collection types.
get in interface GettableByIndexDatai - the index to retrieve.targetClass - The Java type the value should be converted to.ith value converted to the given Java type.public <T> T get(int i,
TypeToken<T> targetType)
GettableByIndexDataith value converted to the given Java type.
This method uses the CodecRegistry to find a codec to convert the underlying CQL
type to the given Java type.

TypeCodec<T> codec)
GettableByIndexDataith value converted using the given TypeCodec.
This method entirely bypasses the CodecRegistry and forces the driver to use the
given codec instead. This can be useful if the codec would collide with a previously registered
one, or if you want to use the codec just once without registering it.
It is the caller's responsibility to ensure that the given codec accepts the underlying CQL type; failing to do so may result in
InvalidTypeExceptions being thrown.
