extends AttributeImpl
implements DefaultOperatorAttribute

Constructor Detail


public DefaultOperatorAttributeImpl()
Method Detail


public void setOperator(DefaultOperatorAttribute.Operator operator)
Specified by:
setOperator in interface DefaultOperatorAttribute


public DefaultOperatorAttribute.Operator getOperator()
Specified by:
getOperator in interface DefaultOperatorAttribute


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.
