## Uses of Interface
org.apache.lucene.util.Attribute

Packages that use Attribute
org.apache.lucene.analysis: API and code to convert text into indexable/searchable tokens.
org.apache.lucene.analysis.tokenattributes: General-purpose attributes for text analysis.
org.apache.lucene.search: Code to search indices.

Uses of Attribute in org.apache.lucene.analysis

Subinterfaces of Attribute in org.apache.lucene.analysis
`static interface` `NumericTokenStream.NumericTermAttribute` Expert: Use this attribute to get the details of the currently generated token.

Classes in org.apache.lucene.analysis that implement Attribute
`static class` `NumericTokenStream.NumericTermAttributeImpl` Implementation of `NumericTokenStream.NumericTermAttribute`.
`class` `Token` A Token is an occurrence of a term from the text of a field.

Method parameters in org.apache.lucene.analysis with type arguments of type Attribute
`AttributeImpl` `Token.TokenAttributeFactory.createAttributeInstance(Class<? extends Attribute> attClass)`

Uses of Attribute in org.apache.lucene.analysis.tokenattributes

Subinterfaces of Attribute in org.apache.lucene.analysis.tokenattributes
`interface` `CharTermAttribute` The term text of a Token.
`interface` `FlagsAttribute` This attribute can be used to pass different flags down the `Tokenizer` chain, e.g.
`interface` `KeywordAttribute` This attribute can be used to mark a token as a keyword.
`interface` `OffsetAttribute` The start and end character offset of a Token.
`interface` `PayloadAttribute` The payload of a Token.
`interface` `PositionIncrementAttribute` Determines the position of this token relative to the previous Token in a TokenStream, used in phrase searching.
`interface` `PositionLengthAttribute` Determines how many positions this token spans.
`interface` `TermToBytesRefAttribute` This attribute is requested by TermsHashPerField to index the contents.
`interface` `TypeAttribute` A Token's lexical type.

Classes in org.apache.lucene.analysis.tokenattributes that implement Attribute
`class` `CharTermAttributeImpl` Default implementation of `CharTermAttribute`.
`class` `FlagsAttributeImpl` Default implementation of `FlagsAttribute`.
`class` `KeywordAttributeImpl` Default implementation of `KeywordAttribute`.
`class` `OffsetAttributeImpl` Default implementation of `OffsetAttribute`.
`class` `PayloadAttributeImpl` Default implementation of `PayloadAttribute`.
`class` `PositionIncrementAttributeImpl` Default implementation of `PositionIncrementAttribute`.
`class` `PositionLengthAttributeImpl` Default implementation of `PositionLengthAttribute`.
`class` `TypeAttributeImpl` Default implementation of `TypeAttribute`.

Uses of Attribute in org.apache.lucene.search

Subinterfaces of Attribute in org.apache.lucene.search
`interface` `BoostAttribute` Add this `Attribute` to a `TermsEnum` returned by `MultiTermQuery.getTermsEnum(Terms,AttributeSource)` and update the boost on each returned term.
`static interface` `FuzzyTermsEnum.LevenshteinAutomataAttribute` reuses compiled automata across different segments, because they are independent of the index
`interface` `MaxNonCompetitiveBoostAttribute` Add this `Attribute` to a fresh `AttributeSource` before calling `MultiTermQuery.getTermsEnum(Terms,AttributeSource)`.

Classes in org.apache.lucene.search that implement Attribute
`class` `BoostAttributeImpl` Implementation class for `BoostAttribute`.
`static class` `FuzzyTermsEnum.LevenshteinAutomataAttributeImpl` Stores compiled automata as a list (indexed by edit distance)
`class` `MaxNonCompetitiveBoostAttributeImpl` Implementation class for `MaxNonCompetitiveBoostAttribute`.

Uses of Attribute in org.apache.lucene.util

Classes in org.apache.lucene.util that implement Attribute
`class` `AttributeImpl` Base class for Attributes that can be added to a `AttributeSource`.

Methods in org.apache.lucene.util with type parameters of type Attribute

`

`<A extends Attribute> A`

`

`AttributeSource.addAttribute(Class<A> attClass)`
The caller must pass in a Class<? extends Attribute> value.

`

`<A extends Attribute> A`

`

`AttributeSource.getAttribute(Class<A> attClass)`
The caller must pass in a Class<? extends Attribute> value.

Methods in org.apache.lucene.util that return types with arguments of type Attribute
`Iterator<Class<? extends Attribute>>` `AttributeSource.getAttributeClassesIterator()` Returns a new iterator that iterates the attribute classes in the same order they were added in.

Method parameters in org.apache.lucene.util with type arguments of type Attribute
`abstract AttributeImpl` `AttributeSource.AttributeFactory.createAttributeInstance(Class<? extends Attribute> attClass)` returns an `AttributeImpl` for the supplied `Attribute` interface class.
`boolean` `AttributeSource.hasAttribute(Class<? extends Attribute> attClass)` The caller must pass in a Class<? extends Attribute> value.
`void` `AttributeReflector.reflect(Class<? extends Attribute> attClass, String key, Object value)` This method gets called for every property in an `AttributeImpl`/`AttributeSource` passing the class name of the `Attribute`, a key and the actual value.
