CTOR.

Constructs a name generator that will build names starting with the specified prefix

virtual

DTOR.

Member Function Documentation

virtual DtUnicode makVrv::DtUniqueNameGenerator::generateName ( )

virtual

Allocate and return a new unique name.

To allow the name to be reused, call release() on it

virtual void makVrv::DtUniqueNameGenerator::releaseName ( const DtUnicode &  name )

virtual

Release a name so that it can be reused.

virtual void makVrv::DtUniqueNameGenerator::takeName ( const DtUnicode &  name )

virtual

Register a name to not use for generateName()

For example, if an object already exists with the name "sensor_2", calling takeName("sensor_2") means that generateName() will generate the sequence "sensor_1", "sensor_3", "sensor_4", and so on.
