Member Typedef Documentation

◆ Ref

typedef deTObjectReference<decBaseFileReader> decBaseFileReader::Ref

Type holding strong reference.

Constructor & Destructor Documentation

◆ decBaseFileReader()

decBaseFileReader::decBaseFileReader ( )

Create file reader.

◆ ~decBaseFileReader()

virtual decBaseFileReader::~decBaseFileReader ( )

protectedvirtual

Clean up file reader.

Note: Subclasses should set their destructor protected too to avoid users accidently deleting a reference counted object through the object pointer. Only FreeReference() is allowed to delete the object.
