java.lang.Object

org.apache.lucene.util.AttributeImpl

org.apache.lucene.analysis.tokenattributes.PayloadAttributeImpl

All Implemented Interfaces:

Cloneable, PayloadAttribute, Attribute

public class PayloadAttributeImpl
extends AttributeImpl
implements PayloadAttribute, Cloneable

Default implementation of PayloadAttribute.

Constructor Summary

Constructors

Constructor and Description
PayloadAttributeImpl() Initialize this attribute with no payload.
PayloadAttributeImpl(BytesRef payload) Initialize this attribute with the given payload.

Method Summary

Modifier and Type	Method and Description
void	clear() Clears the values in this AttributeImpl and resets it to its default value.
PayloadAttributeImpl	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.
boolean	equals(Object other)
BytesRef	getPayload() Returns this Token's payload.
int	hashCode()
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.
void	setPayload(BytesRef payload) Sets this Token's payload.

Constructor Detail

PayloadAttributeImpl

public PayloadAttributeImpl()

Initialize this attribute with no payload.

PayloadAttributeImpl

public PayloadAttributeImpl(BytesRef payload)

Initialize this attribute with the given payload.

Method Detail

getPayload

public BytesRef getPayload()

Description copied from interface: PayloadAttribute

Returns this Token's payload.

Specified by:

getPayload in interface PayloadAttribute

See Also:

PayloadAttribute.setPayload(BytesRef)

setPayload

public void setPayload(BytesRef payload)

Description copied from interface: PayloadAttribute

Sets this Token's payload.

Specified by:

setPayload in interface PayloadAttribute

See Also:

PayloadAttribute.getPayload()

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

clone

public PayloadAttributeImpl 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

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
