Description¶

TBinaryField is an abstract class, designed to handle binary data of variable size. It overrides some of the properties and methods of the TField class to be able to work with binary field data, such as retrieving the contents as a string or as a variant.

One must never create an instance of TBinaryField manually, it is an abstract class. Instead, a descendent class such as TBytesField or TVarBytesField should be created.
