interface |
CharTermAttribute
The term text of a Token.
|
interface |
FlagsAttribute
This attribute can be used to pass different flags down the
Tokenizer chain,
eg from one TokenFilter to another one. |
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
The positionIncrement determines the position of this token
relative to the previous Token in a TokenStream, used in phrase
searching.
|
interface |
PositionLengthAttribute
The positionLength determines how many positions this
token spans.
|
interface |
TermAttribute
Deprecated.
Use
CharTermAttribute instead. |
interface |
TypeAttribute

AttributeImpl
Base class for Attributes that can be added to a
AttributeSource . |
Modifier and Type | Method and Description |
---|---|
<A extends Attribute> |
AttributeSource.addAttribute(Class<A> attClass)
The caller must pass in a Class<? extends Attribute> value.
|
<A extends Attribute> |

Iterator<Class<? extends Attribute>> |
AttributeSource.getAttributeClassesIterator()
Returns a new iterator that iterates the attribute classes
in the same order they were added in.
|

---|---|
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. |
