Method Details
-
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
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
-
hashCode
public int hashCode() -
equals
-
isKeyword
public boolean isKeyword()Description copied from interface:KeywordAttributeReturnstrueif the current token is a keyword, otherwisefalse- Specified by:
isKeywordin interfaceKeywordAttribute- Returns:
trueif the current token is a keyword, otherwisefalse- See Also:
-
setKeyword
public void setKeyword(boolean isKeyword) Description copied from interface:KeywordAttributeMarks the current token as keyword if set totrue.- Specified by:
setKeywordin interfaceKeywordAttribute- Parameters:
isKeyword-trueif the current token is a keyword, otherwisefalse.- See Also:
-
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:
