/**********************
|
|
This is the standard TypeConverter class used with DATETIME columns
|
|
in the Ndb Adapter.
|
|
|
|
DATETIME columns are read and written using a MySQLTime structure,
|
|
which provides lossless interchange.
|
|
|
|
This Converter converts between MySQLTime and standard JavaScript Date.
|
|
|
|
While convenient, such a conversion can result in lost precision.
|
|
JavaSCript Date supports millisecond precision, while MySQL DATETIME
|
|
can support up to microsecond precision.
|
|
|
|
An application can override this converter and use MySQLTime directly:
|
|
sessionFactory.registerTypeConverter("DATETIME", null);
|
|
|
|
Or replace this converter with a custom one:
|
|
sessionFactory.registerTypeConverter("DATETIME", myConverterClass);
|
|
