DataSourceStream Interface

Interface for returning binary documents through the DataSource3 interface.

File

File: DataSourceStream.java

Package: com.dtsearch.engine

Syntax

Java

public interface DataSourceStream;

Methods

	Name	Description
	getLength	Return the number of bytes in this document
	read	Read bytes from the document, and advance the read position. Returns the number of bytes read.
	seek	Set the location for the next read operation and return true if the position is a valid offset within the file.

Remarks

A data source can return binary documents as a byte array (using setDocBytes), a disk file, or as an object that implements the DataSourceStream interface. The DataSourceStream interface provides seek, read, and getLength methods that the dtSearch Engine can use to read a binary document during indexing.
