Constructor Detail

EitherSerializerSnapshot

public EitherSerializerSnapshot()

Deprecated.

Constructor for read instantiation.

EitherSerializerSnapshot

public EitherSerializerSnapshot(TypeSerializer<L> leftSerializer,
                                TypeSerializer<R> rightSerializer)

Deprecated.

Constructor to create the snapshot for writing.

Method Detail

getCurrentVersion

public int getCurrentVersion()

Deprecated.

Description copied from interface: TypeSerializerSnapshot

Returns the version of the current snapshot's written binary format.

Specified by:

getCurrentVersion in interface TypeSerializerSnapshot<L>

Returns:

the version of the current snapshot's written binary format.

writeSnapshot

public void writeSnapshot(DataOutputView out)
                   throws IOException

Deprecated.

Description copied from interface: TypeSerializerSnapshot

Writes the serializer snapshot to the provided DataOutputView. The current version of the written serializer snapshot's binary format is specified by the TypeSerializerSnapshot.getCurrentVersion() method.

Specified by:

writeSnapshot in interface TypeSerializerSnapshot<L>

Parameters:

out - the DataOutputView to write the snapshot to.

Throws:

IOException - Thrown if the snapshot data could not be written.

See Also:

TypeSerializerSnapshot.writeVersionedSnapshot(DataOutputView, TypeSerializerSnapshot)

readSnapshot

public void readSnapshot(int readVersion,
                         DataInputView in,
                         ClassLoader classLoader)
                  throws IOException

Deprecated.

Description copied from interface: TypeSerializerSnapshot

Reads the serializer snapshot from the provided DataInputView. The version of the binary format that the serializer snapshot was written with is provided. This version can be used to determine how the serializer snapshot should be read.

Specified by:

readSnapshot in interface TypeSerializerSnapshot<L>

Parameters:

readVersion - version of the serializer snapshot's written binary format

in - the DataInputView to read the snapshot from.

classLoader - the user code classloader

Throws:

IOException - Thrown if the snapshot data could be read or parsed.

See Also:

TypeSerializerSnapshot.readVersionedSnapshot(DataInputView, ClassLoader)

restoreSerializer

public EitherSerializer<L,R> restoreSerializer()

Deprecated.

Description copied from interface: TypeSerializerSnapshot

Recreates a serializer instance from this snapshot. The returned serializer can be safely used to read data written by the prior serializer (i.e., the serializer that created this snapshot).

Specified by:

restoreSerializer in interface TypeSerializerSnapshot<L>

Returns:

a serializer instance restored from this serializer snapshot.

getNestedSerializerSnapshots

@Nullable
public TypeSerializerSnapshot<?>[] getNestedSerializerSnapshots()

Deprecated.
