A dtsInputStream is an abstraction of a document with seek() and read() methods for accessing data and a dtsFileInfo with file description information (modification date, size, etc.) 

A dtsDataSource object returns dtsInputStream objects in response to the getNextDoc callback function. 

Derived classes DTS_OVERRIDE_KEYWORD seek() and read() to provide access to the data associated with the document. 

The derived class DMemoryInputStream can create a dtsInputStream from data in a memory buffer. 

The derived class DFileInputStream can create a dtsInputStream from a disk file.
