Class SentenceAttributeImpl
- java.lang.Object
-
- org.apache.lucene.util.AttributeImpl
-
- org.apache.lucene.analysis.tokenattributes.SentenceAttributeImpl
-
- All Implemented Interfaces:
Cloneable,SentenceAttribute,Attribute
public class SentenceAttributeImpl extends AttributeImpl implements SentenceAttribute
Default implementation ofSentenceAttribute.The current implementation is coincidentally identical to
FlagsAttributeImplIt 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.

Method Detail
-
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
-
copyTo
public void copyTo(AttributeImpl target)
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
public void reflectWith(AttributeReflector reflector)
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:
reflectWithin classAttributeImpl- See Also:

getSentenceIndex
public int getSentenceIndex()
Description copied from interface:SentenceAttributeGet the sentence index for the current token- Specified by:
getSentenceIndexin interfaceSentenceAttribute- Returns:
- The index of the sentence
- See Also:
SentenceAttribute.getSentenceIndex()
-
setSentenceIndex
public void setSentenceIndex(int sentence)
Description copied from interface:SentenceAttributeSet the sentence of the current token- Specified by:
setSentenceIndexin interfaceSentenceAttribute- See Also:
SentenceAttribute.setSentenceIndex(int sentenceIndex)
