Method Detail

checkAccess

private static final <E> boolean checkAccess(Log out,
                                             Map<MemorizableSequence<E>,SequenceMemento<E>> mementos,
                                             Sequence<E> sequence)

Checks access rules to guarded mementos.

Type Parameters:

E - The type of values delivered by sequence.

Parameters:

out - The log to use; never null.

mementos - The map to storing the created mementos; never null.

sequence - The sequence identifying the memento to use; never null.

Returns:

True upon success, false if not.

create

private static final <E> boolean create(Log out,
                                        Map<MemorizableSequence<E>,SequenceMemento<E>> mementos,
                                        MemorizableSequence<E> sequence)

Creates a new memento acquired from sequence.

Type Parameters:

E - The type of values delivered by sequence.

Parameters:

out - The log to use; never null.

mementos - The map to store the created memento; never null.

sequence - The sequence to create the memento; never null.

Returns:

True upon success, false if not.

createMap

private static final <E> Map<MemorizableSequence<E>,SequenceMemento<E>> createMap()

Creates a new map to store (memorizable sequence, memento) pairs.

Type Parameters:

E - The type of values delivered by applicable sequences.

Returns:

A new map to use; never null.

main

public static void main(String[] args)

Executes the Memento tests.

Parameters:

args - The arguments to supply to test(Log, Arguments), if any; can be null.

test

public boolean test(Log out,
                    Arguments arguments)

Description copied from interface: Testable

Performs the specific tests and report the outcome to the log supplied as log.

Arguments to control log-level:

• -log: a boolean value (as a string) indicating if class logging is enabled for relevant classes.

• -log.verbose: a boolean value (as a string) indicating if class logging is enabled for relevant classes that generates verbose output.

Specified by:

test in interface Testable

Parameters:

out - The log to report the test outcome to; cannot be null.

arguments - Additional arguments, if any.

Returns:

True if the tests succeeded, false if not.

use

private static final <E> boolean use(Log out,
                                     Map<MemorizableSequence<E>,SequenceMemento<E>> mementos,
                                     MemorizableSequence<E> sequence)

Updates sequence using the relevant memento stored in mementos.

Type Parameters:

E - The type of values delivered by sequence.

Parameters:

out - The log to use; never null.

mementos - The map to storing the created memento; never null.

sequence - The sequence to be updated; never null.

Returns:

True upon success, false if not.
