Examples of org.modeshape.jcr.spi.index.ResultWriter

org.modeshape.jcr.spi.index.ResultWriter
A writer passed by ModeShape to a {@link org.modeshape.jcr.spi.index.provider.Filter.Results} instance when the query engineneeds additional results for the query.
Instances of this type are created by ModeShape and passed into the {@link org.modeshape.jcr.spi.index.provider.Filter.Results#getNextBatch(ResultWriter,int)} method. Thus, providers do not needto implement this interface (except maybe for testing purposes).
