List of leaves() Examples

Examples of leaves()

org.apache.lucene.index.CompositeReaderContext.leaves()
org.apache.lucene.index.DirectoryReader.leaves()
org.apache.lucene.index.IndexReader.leaves()
Returns the reader's leaves, or itself if this reader is atomic. This is a convenience method calling {@code this.getContext().leaves()}. @see IndexReaderContext#leaves()
org.apache.lucene.index.IndexReaderContext.leaves()
Returns the context's leaves if this context is a top-level context. For convenience, if this is an {@link AtomicReaderContext} thisreturns itself as the only leaf.
Note: this is convenience method since leaves can always be obtained by walking the context tree using {@link #children()}. @throws UnsupportedOperationException if this is not a top-level context. @see #children()
org.apache.lucene.index.MultiReader.leaves()

Examples of org.apache.lucene.index.DirectoryReader.leaves()

    assertFalse(_fileSystem.exists(_path));
    assertFalse(_fileSystem.exists(_badRowIdsPath));
    assertTrue(_fileSystem.exists(_inUsePath));


    DirectoryReader reader = DirectoryReader.open(_mainDirectory);
    while (reader.leaves().size() > 1) {
      reader.close();
      _mainWriter.forceMerge(1, true);
      _mainWriter.commit();
      reader = DirectoryReader.open(_mainDirectory);
