Method Detail

externalToInternal

public T 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,T extends Geometry>

Parameters:

node - the value's external form.

Returns:

the value's internal form.

parseGeometry

protected abstract T parseGeometry(@NonNull
                                   String s)

parseGeometry

protected abstract T parseGeometry(@NonNull
                                   byte[] b)

internalToExternal

public JsonNode internalToExternal(T value)

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,T extends Geometry>

Parameters:

value - the value's internal form.

Returns:

the value's external form.
