bool isDefault() const
Test if the link is in the default state.

DataLinkBase::clear
void clear()
Clear the link (make it null)

DataLinkBase::toTransient
virtual bool toTransient()=0
Reset the object's internal cache.

DataLinkBase::DataLinkBase
DataLinkBase()
Default constructor.

DataLinkBase::~DataLinkBase
virtual ~DataLinkBase()
Destructor.
