Method Detail
-
getFlags
public int getFlags()
Description copied from interface:FlagsAttributeGet the bitset for any bits that have been set.- Specified by:
getFlagsin interfaceFlagsAttribute- Returns:
- The bits
- See Also:
FlagsAttribute.getFlags()
-
setFlags
public void setFlags(int flags)
Description copied from interface:FlagsAttributeSet the flags to a new bitset.- Specified by:
setFlagsin interfaceFlagsAttribute- See Also:
FlagsAttribute.getFlags()
-
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:
