com.bigdata.rdf.lexicon.BlobsWriteProc.Result

All Implemented Interfaces:

Externalizable, Serializable

Enclosing class:

BlobsWriteProc

public static class BlobsWriteProc.Result
extends Object
implements Externalizable

Object encapsulates the discovered / assigned IVs and provides efficient serialization for communication of those data to the client.

Field Detail

totalBucketSize

public long totalBucketSize

The total size of the hash collision buckets examined across all Values in the request. Each time a Value is resolved to a hash collision bucket, the size of that bucket is incremented against this field. Thus it will double count a bucket if the same bucket is visited more than once for the request.

maxBucketSize

public int maxBucketSize

The size of the largest hash collision bucket examined across all the Values in the request.

counters

public int[] counters

The counters assigned to each Value in the request. The indices of this array are correlated with the indices of the array provided to the request.

Note: The actual counters values are SHORTs, not INTs. However, BlobsIndexHelper.NOT_FOUND is an INT value used to indicate that the desired BlobIV was not discovered in the index. That means that we need to interchange and represent the counters as an int[].

Constructor Detail

BlobsWriteProc.Result

public BlobsWriteProc.Result()

De-serialization constructor.

BlobsWriteProc.Result

public BlobsWriteProc.Result(long totalBucketSize,
                     int maxBucketSize,
                     int[] counters)

Parameters:

totalBucketSize - The total bucket size across all buckets examined.

maxBucketSize - The size of the largest collision bucket examined.

ivs - The assigned/resolved collision counters.
