getPartOfSpeech
public String getPartOfSpeech()
- Specified by:
getPartOfSpeech
in interfacePartOfSpeechAttribute
-
setToken
public void setToken(Token token)
- Specified by:
setToken
in interfacePartOfSpeechAttribute
-
clear
public void clear()
Description copied from class:AttributeImpl
Clears 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:
clear
in classAttributeImpl
-
copyTo
public void copyTo(AttributeImpl target)
Description copied from class:AttributeImpl
Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.- Specified by:
copyTo
in classAttributeImpl
-
reflectWith
public void reflectWith(AttributeReflector reflector)
Description copied from class:AttributeImpl
This method is for introspection of attributes, it should simply add the key/values this attribute holds to the givenAttributeReflector
.The default implementation calls
AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)
for all non-static fields from the implementing class, using the field name as key and the field value as value. The Attribute class is also determined by reflection. Please note that the default implementation can only handle single-Attribute implementations.Custom 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
Attribute
interfaces 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.null
properties!- Overrides:
