Method Detail

clone

public SelectOneStep<S,E> clone()
                         throws java.lang.CloneNotSupportedException

Description copied from interface: Step

Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication. When cloning a step, it is important that the steps, the cloned step is equivalent to the state of the step when reset() is called. Moreover, the previous and next steps should be set to EmptyStep.

Specified by:

clone in interface Step

Overrides:

clone in class SelectStep

Returns:

The cloned step

Throws:

java.lang.CloneNotSupportedException

toString

public java.lang.String toString()

Overrides:

toString in class SelectStep
