Class TermsHash

java.lang.Object

org.apache.lucene.index.TermsHash

Direct Known Subclasses:

FreqProxTermsWriter, TermVectorsConsumer

abstract class TermsHash
extends Object

This class is passed each token produced by the analyzer on each field during indexing, and it stores these tokens in a hash table, and allocates separate byte streams per token. Consumers of this class, eg FreqProxTermsWriter and TermVectorsConsumer, write their own byte streams under each term.
