public abstract class ByteExtensibleStrategy
extends ByteAbstractStrategy

Common code for extensible strategies for providing test data of type byte.

This type provides an extension mechanism that is easier to use than a composite, wherein subclasses of subclasses can override the addData() method to provide additional data for testing.

Method Detail

byteIterator

public ByteIterator byteIterator()
Description copied from interface: ByteStrategyType
Compute a fresh ByteIterator, which can be used to provide test data of type byte. The ByteIterator returned should be freshly created. Usually it should not be at its end. However, in rare cases it might make sense to have an empty iterator be computed (e.g., by filtering).


getData

protected byte[] getData()
Create and return the data for the iterations. This is should only be called once for this object.


defaultData

protected abstract byte[] defaultData()
Create and return the default data for the iterations. This is should only be called once for this object.


addData

protected byte[] addData()
Subclasses can override this to make simple extensions to the data used.
