Package org.apache.lucene.store.instantiated

Class InstantiatedIndexWriter

  • All Implemented Interfaces:
    Closeable, AutoCloseable
    @Deprecated
public class InstantiatedIndexWriter
extends Object
implements Closeable
    Deprecated.
    contrib/instantiated will be removed in 4.0; you can use the memory codec to hold all postings in RAM
    This class, similar to IndexWriter, has no locking mechanism.

    InstantiatedIndexReader is navigating the same instances in memory as this writer is updating so searchers active while you are committing are bound to throw exceptions.

    Consider using InstantiatedIndex as if it was immutable.

    IndexWriter

      • setMergeFactor

        public void setMergeFactor​(int mergeFactor)
        Deprecated.
        The sweetspot for this implementation is somewhere around 2500 at 2K text large documents.

      • setInfoStream

        public void setInfoStream​(PrintStream infoStream)
        Deprecated.
        If non-null, information about merges and a message when maxFieldLength is reached could be printed to this -- currently not yet implemented.

      • addIndexes

        public void addIndexes​(org.apache.lucene.index.IndexReader[] readers)
        Deprecated.

      • getInfoStream

        public PrintStream getInfoStream()
        Deprecated.

      • docCount

        public int docCount()
        Deprecated.
        Returns the number of documents currently in this index.

      • commit

        public void commit()
            throws IOException
        Deprecated.
        Locks the index and commits the buffered documents.
        Throws:
        IOException

      • addDocument

        public void addDocument​(org.apache.lucene.document.Document doc)
                 throws IOException
        Deprecated.
        Adds a document to this index. If the document contains more than setMaxFieldLength(int) terms for a given field, the remainder are discarded.
        Throws:
        IOException

      • addDocument

        public void addDocument​(org.apache.lucene.document.Document doc,
                        org.apache.lucene.analysis.Analyzer analyzer)
                 throws IOException
        Deprecated.
        Adds a document to this index, using the provided analyzer instead of the value of getAnalyzer(). If the document contains more than setMaxFieldLength(int) terms for a given field, the remainder are discarded.
        Parameters:
        doc -
        analyzer -
        Throws:
        IOException

      • addDocument

        protected void addDocument​(InstantiatedDocument document,

                    throws IOException
        Deprecated.
        Tokenizes a document and adds it to the buffer. Try to do all calculations in this method rather than in commit, as this is a non locking method. Remember, this index implementation expects unlimited memory for maximum speed.
        Parameters:
        document -
        analyzer -
        Throws:
        IOException
