TBinaryObjectReader class

In unit Classes

Driver class descendant which reads component data stored in binary format.

Declaration

pascal

TBinaryObjectReader = class(TAbstractObjectReader)

Inheritance

TBinaryObjectReader
TAbstractObjectReader

Descends from it: TBidirBinaryObjectReader

Description

The TBinaryObjectReader class reads component data stored in binary form in a file. For this, it overrides or implements all abstract methods from TAbstractObjectReader. No new functionality is added by this class, it is a driver class for the streaming system.

It should never be necessary to create an instance of this class directly. Instead, the WriteComponent call should be used.
