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

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

Modifier and Type	Interface and Description
interface	BytesTermAttribute This attribute can be used if you have the raw term bytes to be indexed.
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	TermFrequencyAttribute Sets the custom term frequency of a term within one document.
interface	TermToBytesRefAttribute This attribute is requested by TermsHashPerField to index the contents.
interface	TypeAttribute A Token's lexical type.

Uses of Attribute in org.apache.lucene.search

Subinterfaces of Attribute in org.apache.lucene.search

Modifier and Type	Interface and Description
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).

Modifier and Type	Class and Description
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.

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

Modifier and Type	Method and Description
<T extends Attribute> T	AttributeSource.addAttribute(Class<T> attClass) The caller must pass in a Class<? extends Attribute> value.
<T extends Attribute> T	AttributeSource.getAttribute(Class<T> attClass) Returns the instance of the passed in Attribute contained in this AttributeSource

Methods in org.apache.lucene.util that return types with arguments of type Attribute

Modifier and Type	Method and Description
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

Modifier and Type	Method and Description
abstract AttributeImpl	AttributeFactory.createAttributeInstance(Class<? extends Attribute> attClass) Returns an AttributeImpl for the supplied Attribute interface class.
AttributeImpl	AttributeFactory.StaticImplementationAttributeFactory.createAttributeInstance(Class<? extends Attribute> attClass)
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.
