Class ByteExtensibleStrategy

java.lang.Object
  org.jmlspecs.jmlunit.strategies.ByteAbstractStrategy
      org.jmlspecs.jmlunit.strategies.ByteExtensibleStrategy

All Implemented Interfaces:

ByteStrategyType, StrategyType

Direct Known Subclasses:

ByteExtensibleStrategyDecorator.ByteExtensibleStrategyDecorator$1, ByteStrategy

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.

private byte[] data

The data to return in the iterations

Specifications: nullable
is in groups: objectState

ByteExtensibleStrategy

public ByteExtensibleStrategy()

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).

Specifications inherited from overridden method in interface ByteStrategyType:

assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;

getData

protected byte[] getData()

Create and return the data for the iterations. This is should only be called once for this object.

Specifications:

protected normal_behavior
assignable objectState;
ensures \result != null;

defaultData

protected abstract byte[] defaultData()

Create and return the default data for the iterations. This is should only be called once for this object.

Specifications:

protected normal_behavior
assignable objectState;
ensures \result != null;

addData

protected byte[] addData()

Subclasses can override this to make simple extensions to the data used.
