public class LineDocMaker
extends BasicDocMaker

A DocMaker reading one line at a time as a Document from a single file. This saves IO cost (over DirDocMaker) of recursing through a directory and opening a new file for every document. It also re-uses its Document and Field instance to improve indexing speed. Config properties: docs.file=<path to the file%gt;

Method Detail

getNextDocData

protected DocData getNextDocData()
                          throws Exception

Description copied from class: BasicDocMaker

Return the data of the next document. All current implementations can create docs forever. When the input data is exhausted, input files are iterated. This re-iteration can be avoided by setting doc.maker.forever to false (default is true).

Specified by:

getNextDocData in class BasicDocMaker

Returns:

data of the next document.

Throws:

NoMoreDataException - if data is exhausted (and 'forever' set to false).

Exception

makeDocument

public Document makeDocument()
                      throws Exception

Description copied from interface: DocMaker

Create the next document.

Specified by:

Overrides:

makeDocument in class BasicDocMaker

Throws:

Exception

makeDocument

public Document makeDocument(int size)
                      throws Exception

Description copied from interface: DocMaker

Create the next document, of the given size by input bytes. If the implementation does not support control over size, an exception is thrown.

Specified by:

Parameters:

size - size of document, or 0 if there is no size requirement.

Throws:

Exception

resetInputs

public void resetInputs()

Description copied from interface: DocMaker

Reset inputs so that the test run would behave, input wise, as if it just started.

Specified by:

numUniqueTexts

public int numUniqueTexts()

Description copied from interface: DocMaker

Return how many real unique texts are available, 0 if not applicable.
