Constructor Detail

SerializedFlowExecutionSnapshot

public SerializedFlowExecutionSnapshot()

Default constructor necessary for Externalizable custom serialization semantics. Should not be called by application code.

SerializedFlowExecutionSnapshot

public SerializedFlowExecutionSnapshot(FlowExecution flowExecution,
                               boolean compress)
                                throws SnapshotCreationException

Creates a new serialized flow execution snapshot.

Parameters:

flowExecution - the flow execution

compress - whether or not to apply compression during snapshotting

Throws:

SnapshotCreationException

Method Detail

isCompressed

public boolean isCompressed()

Returns whether or not the flow execution data in this snapshot is compressed.

unmarshal

public FlowExecution unmarshal(ClassLoader classLoader)
                        throws SnapshotUnmarshalException

Unmarshal the flow execution from this snapshot's data.

Parameters:

Returns:

the unmarashalled flow execution

Throws:

SnapshotUnmarshalException
