Constructor Detail

RawBucketResultNode

public RawBucketResultNode()

Constructs an empty result node.

RawBucketResultNode

public RawBucketResultNode(ResultNode from,
                           ResultNode to)

Create a bucket with the given limits

Parameters:

from - bucket start

to - bucket end

Method Detail

empty

public boolean empty()

Description copied from class: BucketResultNode

Tell if this bucket has zero width. Indicates that is has no value and can be considered a NULL range. An empty range is used by the backend to represent hits that end in no buckets.

Specified by:

empty in class BucketResultNode

Returns:

If this bucket has zero width.

getFrom

public byte[] getFrom()

Obtain the bucket start

Returns:

bucket start

getTo

public byte[] getTo()

Obtain the bucket end

Returns:

bucket end

onGetClassId

protected int onGetClassId()

Overrides:

onGetClassId in class ResultNode

onSerialize

protected void onSerialize(com.yahoo.vespa.objects.Serializer buf)

Overrides:

onSerialize in class com.yahoo.vespa.objects.Identifiable

onDeserialize

protected void onDeserialize(com.yahoo.vespa.objects.Deserializer buf)

Overrides:

onDeserialize in class com.yahoo.vespa.objects.Identifiable

onCmp

protected int onCmp(ResultNode rhs)

Description copied from class: ResultNode

This method must be implemented by all subclasses of this to allow ordering of results. This method is used by the Cloneable implementation.

Specified by:

onCmp in class ResultNode

Parameters:

rhs - The other node to compare with.

Returns:

Comparable result.

hashCode

public int hashCode()

Overrides:

hashCode in class com.yahoo.vespa.objects.Identifiable

visitMembers

public void visitMembers(com.yahoo.vespa.objects.ObjectVisitor visitor)

Overrides:

visitMembers in class com.yahoo.vespa.objects.Identifiable
