Detailed Description

Deprecated:

Classes RWDBVendorDate and RWDBDateVector are deprecated. Please use classes RWDateTime and RWDBTBuffer<RWDateTime>.

RWDBDateVector is used to transfer date values between the application and the database via instances of RWDBBulkReader and RWDBBulkInserter. Class RWDBDateVector implements basic vector methods and adds null processing capabilities similar to RWDBVector. RWDBDateVector objects are produced by RWDBDatabase. The resulting RWDBDateVector elements are RWDBVendorDate instances of the type appropriate for the underlying database.

Synopsis

 #include <rw/db/dbdatevec.h>
 #include <rw/db/dbase.h>

 RWDBDateVector dateVector = db.dateVector(n);

Examples

In the following example, a vector dateVector is produced. The vector could later be used with either an RWDBBulkInserter or an RWDBBulkReader.

 RWDBDateVector dateVector = aDB.dateVector(n);

size_t RWDBDateVector::entries

(

)

const

Returns the number of elements in self.

bool RWDBDateVector::isNull

(

size_t

index

)

const

Returns true if the index ^th element of self is null, otherwise returns false .

size_t RWDBDateVector::length

(

)

const

Returns the number of elements in self.

RWDBVendorDate RWDBDateVector::operator[]

(

size_t

index

)

const

Returns an instance of an RWDBVendorDate, which in turn holds a reference to the underlying vendor date structure held in the index ^th position.

void RWDBDateVector::setNull

(

size_t

index

)

Sets the index ^th element of self to null.

void RWDBDateVector::unsetNull

(

size_t

index

)

Sets the index ^th element of self to not null.
