Constructor	Description
BytesRefBuilderTermAttributeImpl()	Sole constructor no-op

Method Summary

Modifier and Type	Method	Description
BytesRefBuilder	builder()	Returns the builder from which the term is derived.
void	clear()	Clears the values in this AttributeImpl and resets it to its default value.
AttributeImpl	clone()	In most cases the clone is, and should be, deep in order to be able to properly capture the state of all attributes.
void	copyTo(AttributeImpl target)	Copies the values from this Attribute into the passed-in target attribute.
BytesRef	getBytesRef()	Retrieve this attribute's BytesRef.
void	reflectWith(AttributeReflector reflector)	This method is for introspection of attributes, it should simply add the key/values this attribute holds to the given AttributeReflector.
CharSequence	toUTF16()	Returns the term represented as UTF-16

Method Details

builder

public BytesRefBuilder builder()

Description copied from interface: ConcatenateGraphFilter.BytesRefBuilderTermAttribute

Returns the builder from which the term is derived.

Specified by:

builder in interface ConcatenateGraphFilter.BytesRefBuilderTermAttribute

getBytesRef

public BytesRef getBytesRef()

Description copied from interface: TermToBytesRefAttribute

Retrieve this attribute's BytesRef. The bytes are updated from the current term. The implementation may return a new instance or keep the previous one.

Specified by:

getBytesRef in interface TermToBytesRefAttribute

Returns:

a BytesRef to be indexed (only stays valid until token stream gets incremented)

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

clone

public AttributeImpl clone()

Description copied from class: AttributeImpl

In most cases the clone is, and should be, deep in order to be able to properly capture the state of all attributes.

Overrides:

clone 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

toUTF16

public CharSequence toUTF16()

Description copied from interface: ConcatenateGraphFilter.BytesRefBuilderTermAttribute

Returns the term represented as UTF-16

Specified by:

toUTF16 in interface ConcatenateGraphFilter.BytesRefBuilderTermAttribute
