Constructor Detail

### PerfRunData

    public PerfRunData(Config config)
                throws Exception

Throws:
  `Exception`

Method Detail

### close

    public void close()
               throws IOException

  Specified by:
    `close` in interface `Closeable`
  Throws:
    `IOException`

### reinit

    public void reinit(boolean eraseIndex)
                throws Exception

  Throws:
    `Exception`

### getPerfObject

    public Object getPerfObject(String key)

  Returns an object that was previously set by `setPerfObject(String, Object)`.

### setPerfObject

    public void setPerfObject(String key,
                              Object obj)

  Sets an object that is required by `PerfTask`s, keyed by the given `key`. If the object implements `Closeable`, it will be closed by `close()`.

### setStartTimeMillis

    public long setStartTimeMillis()

### getStartTimeMillis

    public long getStartTimeMillis()

  Returns:
    Start time in milliseconds

### getPoints

    public Points getPoints()

  Returns:
    Returns the points.

### getDirectory

    public org.apache.lucene.store.Directory getDirectory()

  Returns:
    Returns the directory.

### setDirectory

    public void setDirectory(org.apache.lucene.store.Directory directory)

  Parameters:
    `directory` - The directory to set.

### getTaxonomyDir

    public org.apache.lucene.store.Directory getTaxonomyDir()

  Returns:
    Returns the taxonomy directory

### setTaxonomyReader

    public void setTaxonomyReader(org.apache.lucene.facet.taxonomy.TaxonomyReader taxoReader)
                           throws IOException

  Set the taxonomy reader. Takes ownership of that taxonomy reader, that is, internally performs taxoReader.incRef() (If caller no longer needs that reader it should decRef()/close() it after calling this method, otherwise, the reader will remain open).

  Parameters:
    `taxoReader` - The taxonomy reader to set.
  Throws:
    `IOException`

### getTaxonomyReader

    public org.apache.lucene.facet.taxonomy.TaxonomyReader getTaxonomyReader()

  Returns:
    Returns the taxonomyReader. NOTE: this returns a reference. You must call TaxonomyReader.decRef() when you're done.

### setTaxonomyWriter

    public void setTaxonomyWriter(org.apache.lucene.facet.taxonomy.TaxonomyWriter taxoWriter)

  Parameters:
    `taxoWriter` - The taxonomy writer to set.

### getTaxonomyWriter

    public org.apache.lucene.facet.taxonomy.TaxonomyWriter getTaxonomyWriter()

### getIndexReader

    public org.apache.lucene.index.IndexReader getIndexReader()

  Returns:
    Returns the indexReader. NOTE: this returns a reference. You must call IndexReader.decRef() when you're done.

### getIndexSearcher

    public org.apache.lucene.search.IndexSearcher getIndexSearcher()

  Returns:
    Returns the indexSearcher. NOTE: this returns a reference to the underlying IndexReader. You must call IndexReader.decRef() when you're done.

### setIndexReader

    public void setIndexReader(org.apache.lucene.index.IndexReader indexReader)
                        throws IOException

  Set the index reader. Takes ownership of that index reader, that is, internally performs indexReader.incRef() (If caller no longer needs that reader it should decRef()/close() it after calling this method, otherwise, the reader will remain open).

  Parameters:
    `indexReader` - The indexReader to set.
  Throws:
    `IOException`

### getIndexWriter

    public org.apache.lucene.index.IndexWriter getIndexWriter()

  Returns:
    Returns the indexWriter.

### setIndexWriter

    public void setIndexWriter(org.apache.lucene.index.IndexWriter indexWriter)

  Parameters:
    `indexWriter` - The indexWriter to set.

### getAnalyzer

    public org.apache.lucene.analysis.Analyzer getAnalyzer()

  Returns:
    Returns the anlyzer.

### setAnalyzer

    public void setAnalyzer(org.apache.lucene.analysis.Analyzer analyzer)

### getDocMaker

    public DocMaker getDocMaker()

  Returns the docMaker.

### getFacetSource

    public FacetSource getFacetSource()
