Class BoostAttributeImpl

java.lang.Object
  org.apache.lucene.util.AttributeImpl
      org.apache.lucene.queryParser.standard.config.BoostAttributeImpl

All Implemented Interfaces:

Serializable, Cloneable, BoostAttribute, Attribute

public class BoostAttributeImpl
extends AttributeImpl
implements BoostAttribute

This attribute is used by MultiFieldQueryNodeProcessor processor and it should be defined in a FieldConfig. This processor uses this attribute to define which boost a specific field should have when none is defined to it.

Constructor Summary

BoostAttributeImpl()

Method Summary

void	clear() Clears the values in this AttributeImpl and resets it to its default value.
void	copyTo(AttributeImpl target) Copies the values from this Attribute into the passed-in target attribute.
boolean	equals(Object other) All values used for computation of AttributeImpl.hashCode() should be checked here for equality.
float	getBoost()
int	hashCode() Subclasses must implement this method and should compute a hashCode similar to this:
void	setBoost(float boost)
String	toString() The default implementation of this method accesses all declared fields of this object and prints the values in the following syntax:

Method Detail

setBoost

public void setBoost(float boost)

Specified by:

setBoost in interface BoostAttribute

getBoost

public float getBoost()

Specified by:

getBoost in interface BoostAttribute

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

equals

public boolean equals(Object other)

Description copied from class: AttributeImpl

All values used for computation of AttributeImpl.hashCode() should be checked here for equality. see also Object.equals(Object)

Specified by:

equals in class AttributeImpl

hashCode

public int hashCode()

Description copied from class: AttributeImpl

Subclasses must implement this method and should compute a hashCode similar to this:

   public int hashCode() {
     int code = startOffset;
     code = code * 31 + endOffset;
     return code;
   }
 

see also AttributeImpl.equals(Object)

Specified by:

hashCode in class AttributeImpl

toString

public String toString()

Description copied from class: AttributeImpl

The default implementation of this method accesses all declared fields of this object and prints the values in the following syntax:

   public String toString() {
     return "start=" + startOffset + ",end=" + endOffset;
   }
 

This method may be overridden by subclasses.
