Method Detail
-
setTermFrequency
public void setTermFrequency(int termFrequency)
Description copied from interface:TermFrequencyAttributeSet the custom term frequency of the current term within one document.- Specified by:
setTermFrequencyin interfaceTermFrequencyAttribute
-
getTermFrequency
public int getTermFrequency()
Description copied from interface:TermFrequencyAttributeReturns the custom term frequency.- Specified by:
getTermFrequencyin interfaceTermFrequencyAttribute
-
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
-
end
public void end()
Description copied from class:AttributeImplClears the values in this AttributeImpl and resets it to its value at the end of the field. If this implementation implements more than one Attribute interface it clears all.The default implementation simply calls
AttributeImpl.clear()- Overrides:
endin 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:
