public final class TestBloomFilteredLucenePostings
extends PostingsFormat

A class used for testing BloomFilteringPostingsFormat with a concrete delegate (Lucene41). Creates a Bloom filter on ALL fields and with tiny amounts of memory reserved for the filter. DO NOT USE IN A PRODUCTION APPLICATION This is not a realistic application of Bloom Filters as they ordinarily are larger and operate on only primary key type fields.

Method Detail

fieldsConsumer

public FieldsConsumer fieldsConsumer(SegmentWriteState state)
                              throws java.io.IOException

Description copied from class: PostingsFormat

Writes a new segment

Specified by:

fieldsConsumer in class PostingsFormat

Throws:

java.io.IOException

fieldsProducer

public FieldsProducer fieldsProducer(SegmentReadState state)
                              throws java.io.IOException

Description copied from class: PostingsFormat

Reads a segment. NOTE: by the time this call returns, it must hold open any files it will need to use; else, those files may be deleted. Additionally, required files may be deleted during the execution of this call before there is a chance to open them. Under these circumstances an IOException should be thrown by the implementation. IOExceptions are expected and will automatically cause a retry of the segment opening logic with the newly revised segments.

Specified by:

fieldsProducer in class PostingsFormat

Throws:

java.io.IOException
