java.lang.Object

org.apache.lucene.util.AttributeImpl

org.apache.lucene.queryParser.standard.config.DateResolutionAttributeImpl

All Implemented Interfaces:

Serializable, Cloneable, DateResolutionAttribute, Attribute

public class DateResolutionAttributeImpl
extends AttributeImpl
implements DateResolutionAttribute

This attribute is used by ParametricRangeQueryNodeProcessor processor and must be defined in the QueryConfigHandler. This attribute tells the processor which DateTools.Resolution to use when parsing the date.

Method Detail

setDateResolution

public void setDateResolution(DateTools.Resolution dateResolution)

Description copied from interface: DateResolutionAttribute

Sets the default date resolution used by RangeQueryNodes for fields for which no specific date resolutions has been set. Field specific resolutions can be set with

Specified by:

setDateResolution in interface DateResolutionAttribute

Parameters:

dateResolution - the default date resolution to set

getDateResolution

public DateTools.Resolution getDateResolution()

Specified by:

getDateResolution in interface DateResolutionAttribute

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.
