setPositionLength
public void setPositionLength(int positionLength) Description copied from interface:PositionLengthAttribute
Set the position length of this Token.The default value is one.
- Specified by:
setPositionLength
in interfacePositionLengthAttribute
- Parameters:
positionLength
- how many positions this token spans.- See Also:
-
getPositionLength
public int getPositionLength()Description copied from interface:PositionLengthAttribute
Returns the position length of this Token.- Specified by:
getPositionLength
in interfacePositionLengthAttribute
- See Also:
-
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

equals
-
hashCode
public int hashCode() -
copyTo
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
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
.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!- Specified by:
reflectWith
