Returns true if duplicate commit of the operation is equivalent to committing it only once.

Specified by:

isRetryableOnIndeterminateOperationState in interface IndeterminateOperationStateAware

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
