Method Detail

setMaxNonCompetitiveBoost

public void setMaxNonCompetitiveBoost(float maxNonCompetitiveBoost)

Description copied from interface: MaxNonCompetitiveBoostAttribute

This is the maximum boost that would not be competitive.

Specified by:

setMaxNonCompetitiveBoost in interface MaxNonCompetitiveBoostAttribute

getMaxNonCompetitiveBoost

public float getMaxNonCompetitiveBoost()

Description copied from interface: MaxNonCompetitiveBoostAttribute

This is the maximum boost that would not be competitive. Default is negative infinity, which means every term is competitive.

Specified by:

getMaxNonCompetitiveBoost in interface MaxNonCompetitiveBoostAttribute

setCompetitiveTerm

public void setCompetitiveTerm(BytesRef competitiveTerm)

Description copied from interface: MaxNonCompetitiveBoostAttribute

This is the term or null of the term that triggered the boost change.

Specified by:

setCompetitiveTerm in interface MaxNonCompetitiveBoostAttribute

getCompetitiveTerm

public BytesRef getCompetitiveTerm()

Description copied from interface: MaxNonCompetitiveBoostAttribute

This is the term or null of the term that triggered the boost change. Default is null, which means every term is competitoive.

Specified by:

getCompetitiveTerm in interface MaxNonCompetitiveBoostAttribute

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 class AttributeImpl

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 class AttributeImpl

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 given AttributeReflector.

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 to AttributeReflector.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!

Specified by:

reflectWith in class AttributeImpl
