Method Detail

addAll

public boolean addAll(int index,
             Collection<? extends Hold> c)

Specified by:

addAll in interface List<Hold>

Overrides:

addAll in class Vector<Hold>

add

public void add(int index,
       Hold hold)

Specified by:

add in interface List<Hold>

Overrides:

add in class Vector<Hold>

subList

public List<Hold> subList(int fromIndex,
                 int toIndex)

Specified by:

subList in interface List<Hold>

Overrides:

subList in class Vector<Hold>

isUnwinding

public boolean isUnwinding()

Description copied from interface: Spool

Returns true if the spool is unwinding or already unwound. Once true, it never reverts to false.

Specified by:

isUnwinding in interface Spool

unwind

public boolean unwind()

Description copied from interface: Spool

Commences to unwind this spool. Equivalent to unwind(CATCHER_0).

Specified by:

unwind in interface Spool

Returns:

true if unwinding commences with this call; false if it had already commenced.

unwind

public boolean unwind(Catcher<Hold> catcher)

Description copied from interface: Spool

Commences to unwind this spool, removing and releasing each of its holds. Works in LIFO order. Once unwinding is commenced, subsequent calls to this method have no effect.

Specified by:

unwind in interface Spool

Parameters:

catcher - the catcher for any errors or exceptions that occur during unwinding.

Returns:

true if unwinding commences with this call; false if it had already commenced.

addElement

public void addElement(Hold hold)

Overrides:

addElement in class Vector<Hold>

insertElementAt

public void insertElementAt(Hold hold,
                   int index)

Overrides:

insertElementAt in class Vector<Hold>
