Method Summary

Modifier and Type	Method and Description
Map<K,V>	externalToInternal(JsonNode node) 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).
JsonNode	internalToExternal(Map<K,V> map) 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).

Method Detail

externalToInternal

public Map<K,V> externalToInternal(JsonNode node)

Description copied from class: ConvertingCodec

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).

Specified by:

externalToInternal in class ConvertingCodec<JsonNode,Map<K,V>>

Parameters:

node - the value's external form.

Returns:

the value's internal form.

internalToExternal

public JsonNode internalToExternal(Map<K,V> map)

Description copied from class: ConvertingCodec

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).

Specified by:

internalToExternal in class ConvertingCodec<JsonNode,Map<K,V>>

Parameters:

map - the value's internal form.

Returns:

the value's external form.
