Uses of Package
org.apache.lucene.util

Packages that use org.apache.lucene.util
org.apache.lucene.analysis API and code to convert text into indexable/searchable tokens. 
org.apache.lucene.analysis.standard The org.apache.lucene.analysis.standard package contains three fast grammar-based tokenizers constructed with JFlex: 
org.apache.lucene.analysis.tokenattributes   
org.apache.lucene.collation CollationKeyFilter converts each token into its binary CollationKey using the provided Collator, and then encode the CollationKey as a String using IndexableBinaryStringTools, to allow it to be stored as an index term. 
org.apache.lucene.index Code to maintain and access indices. 
org.apache.lucene.queryParser A simple query parser implemented with JavaCC. 
org.apache.lucene.search Code to search indices. 
org.apache.lucene.util Some utility classes. 
 

Classes in org.apache.lucene.util used by org.apache.lucene.analysis
Attribute
          Base interface for attributes.
AttributeImpl
          Base class for Attributes that can be added to a AttributeSource.
AttributeReflector
          This interface is used to reflect contents of AttributeSource or AttributeImpl.
AttributeSource
          An AttributeSource contains a list of different AttributeImpls, and methods to add and get them.
AttributeSource.AttributeFactory
          An AttributeFactory creates instances of AttributeImpls.
Version
          Use by certain classes to match version compatibility across releases of Lucene.
