keyParts

public static String[] keyParts(String encodedKey)
                         throws BadlyFormattedFlowExecutionKeyException

Helper that splits the string-form of an instance of this class into its "parts" so the parts can be easily parsed.

Parameters:

encodedKey - the string-encoded composite flow execution key

Returns:

the composite key parts as a String array (executionId = 0, snapshotId = 1)

Throws:

BadlyFormattedFlowExecutionKeyException
