Class DocMaker

java.lang.Object
  org.apache.lucene.benchmark.byTask.feeds.DocMaker

All Implemented Interfaces:

Closeable

public class DocMaker
extends Object
implements Closeable

Creates Document objects. Uses a ContentSource to generate DocData objects. Supports the following parameters:

• content.source - specifies the ContentSource class to use (default SingleDocSource).
• doc.stored - specifies whether fields should be stored (default false).
• doc.body.stored - specifies whether the body field should be stored (default = doc.stored).
• doc.tokenized - specifies whether fields should be tokenized (default true).
• doc.body.tokenized - specifies whether the body field should be tokenized (default = doc.tokenized).
• doc.tokenized.norms - specifies whether norms should be stored in the index or not. (default false).
• doc.body.tokenized.norms - specifies whether norms should be stored in the index for the body field. This can be set to true, while doc.tokenized.norms is set to false, to allow norms storing just for the body field. (default true).
• doc.term.vector - specifies whether term vectors should be stored for fields (default false).
• doc.term.vector.positions - specifies whether term vectors should be stored with positions (default false).
• doc.term.vector.offsets - specifies whether term vectors should be stored with offsets (default false).
• doc.store.body.bytes - specifies whether to store the raw bytes of the document's content in the document (default false).
• doc.reuse.fields - specifies whether Field and Document objects should be reused (default true).
• doc.index.props - specifies whether the properties returned by
• doc.random.id.limit - if specified, docs will be assigned random IDs from 0 to this limit. This is useful with UpdateDoc for testing performance of IndexWriter.updateDocument. DocData.getProps() will be indexed. (default false).

Constructor Detail

DocMaker

public DocMaker()

Method Detail

getDocState

protected org.apache.lucene.benchmark.byTask.feeds.DocMaker.DocState getDocState()

close

public void close()
           throws IOException

Closes the DocMaker. The base implementation closes the ContentSource, and it can be overridden to do more work (but make sure to call super.close()).

Specified by:

close in interface Closeable

Throws:

IOException

getBytesCount

public long getBytesCount()

Returns the number of bytes generated by the content source since last reset.

getTotalBytesCount

public long getTotalBytesCount()

Returns the total number of bytes that were generated by the content source defined to that doc maker.

makeDocument

public Document makeDocument()
                      throws Exception

Creates a Document object ready for indexing. This method uses the ContentSource to get the next document from the source, and creates a Document object from the returned fields. If reuseFields was set to true, it will reuse Document and Field instances.

Throws:

Exception

makeDocument

public Document makeDocument(int size)
                      throws Exception

Same as makeDocument(), only this method creates a document of the given size input by size.

Throws:

Exception

resetInputs

public void resetInputs()
                 throws IOException

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

Throws:

IOException

setConfig

public void setConfig(Config config)

Set the configuration parameters of this doc maker.
