Method Detail

deserializeKey

public Long deserializeKey(ITuple tuple)

Decodes the key as a commit time.

Specified by:

deserializeKey in interface ITupleSerializer<Long,CommitRecordIndex.Entry>

Overrides:

deserializeKey in class DefaultTupleSerializer<Long,CommitRecordIndex.Entry>

serializeKey

public byte[] serializeKey(Object obj)

Return the unsigned byte[] key for a commit time.

Specified by:

serializeKey in interface ITupleSerializer<Long,CommitRecordIndex.Entry>

Overrides:

serializeKey in class DefaultTupleSerializer<Long,CommitRecordIndex.Entry>

Parameters:

obj - A commit time.

Returns:

An unsigned byte[] which places the object into the total sort order for the index and never null ( null keys are not allowed into an index).

serializeVal

public byte[] serializeVal(CommitRecordIndex.Entry entry)

Return the byte[] value an CommitRecordIndex.Entry.

Specified by:

serializeVal in interface ITupleSerializer<Long,CommitRecordIndex.Entry>

Overrides:

serializeVal in class DefaultTupleSerializer<Long,CommitRecordIndex.Entry>

Parameters:

entry - An Entry.

Returns:

The serialized representation of the object as a byte[] -or- null if the reference is null.

deserialize

public CommitRecordIndex.Entry deserialize(ITuple tuple)

Description copied from class: DefaultTupleSerializer

De-serializes an object from the value stored in the tuple (ignores the key stored in the tuple).

Specified by:

deserialize in interface ITupleSerializer<Long,CommitRecordIndex.Entry>

Overrides:

deserialize in class DefaultTupleSerializer<Long,CommitRecordIndex.Entry>

Parameters:

tuple - The tuple.

Returns:

The de-serialized object.
