Base abstract resource reader class

TObject

Description

This is the base class that represents a resource reader.

A resource reader is an object whose job is to populate a TResources object with resources read from a stream in a specific format.

Typically, a TResources object invokes CheckMagic method of the resource reader when it's searching for a reader able to read a certain stream, and Load method when it wants the reader to read data from the stream.

Usually each resource reader registers itself with TResources class in the initialization section of the unit in which it is implemented: this way a TResources object can find it when probing a stream that is to be read.

Remark: An object of this class should never be directly instantiated: use a descendant class instead.
