DMemoryInputStream Class

Input stream representing a document stored in memory.

class DMemoryInputStream : public DInputStreamBase;

File

DInputStream.h

Remarks

Input streams are used in the dtsDataSource API.

The contents of the input stream can be plain text or binary data. Binary data is parsed in the dtSearch Engine exactly as if it were a disk file, so a memory input stream can be used with binary file formats such as Microsoft Word documents, PDF files, etc.
