All Implemented Interfaces:
Serializable, Cloneable, FieldBoostMapAttribute, Attribute

public class FieldBoostMapAttributeImpl
extends AttributeImpl
implements FieldBoostMapAttribute

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 Detail


public FieldBoostMapAttributeImpl()
Method Detail


public void setFieldBoostMap(Map<String,Float> boosts)
Specified by:
setFieldBoostMap in interface FieldBoostMapAttribute
boosts - a mapping from field name to its default boost


public Map<String,Float> getFieldBoostMap()
Specified by:
getFieldBoostMap in interface FieldBoostMapAttribute


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


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


public boolean equals(Object other)
equals in class Object


public int hashCode()
hashCode in class Object


public String toString()
Description copied from class: AttributeImpl
Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object.

WARNING: For backwards compatibility this method is implemented as return reflectAsString(false). In Lucene 4.0 this default implementation will be removed. The reason for this is the problem of CharTermAttributeImpl.toString() that must return a string representation of the term's char sequence.

It is recommeneded to use AttributeImpl.reflectAsString(boolean) or AttributeImpl.reflectWith(org.apache.lucene.util.AttributeReflector) to get a well-defined output of AttributeImpl's internals.
