Constructor Detail

PositionIncrementAttributeImpl

public PositionIncrementAttributeImpl()

Initialize this attribute with position increment of 1

Method Detail

setPositionIncrement

public void setPositionIncrement(int positionIncrement)

Description copied from interface: PositionIncrementAttribute

Set the position increment. The default value is one.

Specified by:

setPositionIncrement in interface PositionIncrementAttribute

Parameters:

positionIncrement - the distance from the prior term

See Also:

PositionIncrementAttribute.getPositionIncrement()

getPositionIncrement

public int getPositionIncrement()

Description copied from interface: PositionIncrementAttribute

Returns the position increment of this Token.

Specified by:

getPositionIncrement in interface PositionIncrementAttribute

See Also:

PositionIncrementAttribute.setPositionIncrement(int)

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

end

public void end()

Description copied from class: AttributeImpl

Clears 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:

end in class AttributeImpl

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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
