public class SimpleDateCodec extends TypeCodec.PrimitiveIntCodec
TypeCodec
that maps CQL dates to Java primitive ints, representing the number of days
since the Epoch.
This codec can serve as a replacement for the driver's built-in date
codec, when application code prefers to deal with raw days than with LocalDate
instances.
Important: this codec cannot work with SimpleStatement
s! If you try
to insert CQL date values as int
s in a SimpleStatement
, the insertion would
succeed but the values wouldn't be properly encoded. Always use PreparedStatement
s when
using this codec.

Implementors should take care of unquoting and unescaping the given CQL string where
applicable. Null values and empty Strings should be accepted, as well as the string "NULL"
; in most cases, implementations should interpret these inputs has equivalent to a
null
reference.
Implementing this method is not strictly mandatory: internally, the driver only uses it to parse the INITCOND when building the metadata of an aggregate function (and in most cases it will use a built-in codec, unless the INITCOND has a custom type).

TypeCodec
Implementors should take care of quoting and escaping the resulting CQL literal where
applicable. Null values should be accepted; in most cases, implementations should return the
CQL keyword "NULL"
for null
inputs.
Implementing this method is not strictly mandatory. It is used:

this happens);
QueryLogger

AggregateMetadata.asCQLQuery(boolean)
;
toString()
implementation of some objects (UDTValue
, TupleValue
, and the internal representation of a ROWS
response), which may
appear in driver logs.
