Description.
This method is used to obtain a reference to an attribute
value, as a char pointer. This pointer is
aligned appropriately for the datatype. The memory is released
by the NDB API when
NdbTransaction::closeTransaction() is
executed on the transaction which read the value.
Signature.
char* aRef
(
void
) const
Parameters.
A pointer to the attribute value. Because this pointer is
constant, this method can be called anytime after
NdbOperation::getValue() has been called.
Return Value. None.
