Class SentenceAttributeImpl
java.lang.Object
org.apache.lucene.util.AttributeImpl
org.apache.lucene.analysis.tokenattributes.SentenceAttributeImpl
- All Implemented Interfaces:
Cloneable,SentenceAttribute,Attribute
Default implementation of
SentenceAttribute.
The current implementation is coincidentally identical to FlagsAttributeImpl It was
decided to keep it separate because this attribute will NOT be an implied bitmap. Also, this
class may hold other sentence specific data in the future.

clear
public void clear()Description copied from class:AttributeImplClears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.- Specified by:
clearin classAttributeImpl

equals

hashCode
public int hashCode() -
copyTo
Description copied from class:AttributeImplCopies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.- Specified by:
copyToin classAttributeImpl
-
reflectWith
Description copied from class:AttributeImplThis method is for introspection of attributes, it should simply add the key/values this attribute holds to the givenAttributeReflector.Implementations look like this (e.g. for a combined attribute implementation):
public void reflectWith(AttributeReflector reflector) { reflector.reflect(CharTermAttribute.class, "term", term()); reflector.reflect(PositionIncrementAttribute.class, "positionIncrement", getPositionIncrement()); }If you implement this method, make sure that for each invocation, the same set of
Attributeinterfaces and keys are passed toAttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)in the same order, but possibly different values. So don't automatically exclude e.g.nullproperties!- Specified by:
