Method Detail

values

public static TwoSidedList.Direction[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TwoSidedList.Direction c : TwoSidedList.Direction.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TwoSidedList.Direction valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

checkRange

abstract void checkRange(int ind,
                         TwoSidedList<?> list)

Checks whether index ind is in the range of list and throws an appropriate exception if not.

Parameters:

ind - the index to be checked.

list - the twosided list under consideration.

Throws:

IndexOutOfBoundsException -

• for this == Left2Rightif not list.firstIndex() <= ind<list.minFreeIndex()+1.
• for this == Right2Leftif not list.firstIndex()-1 <= ind<list.minFreeIndex() .

The message is always the same: "Index: <ind> Range: <firstIndex> - <minFreeIndex()> exclusively. " .

checkAdd1

abstract void checkAdd1(TwoSidedList<?> list)

Checks in TwoSidedList.add(int, Object, Direction) whether by adding elements causes underrun in TwoSidedList.firstIndex() or overrun in TwoSidedList.minFreeIndex().

Parameters:

list - the twosided list under consideration.

Throws:

IllegalStateException - if adding an object to this list would cause underrun in TwoSidedList.firstIndex() or overrun in TwoSidedList.minFreeIndex() depending on this direction.

TwoSidedList.decFirstIndex(),

checkAddAll

abstract void checkAddAll(int size,
                          TwoSidedList<?> list)

Checks in TwoSidedList.addAll(int, Collection, Direction) whether by adding elements causes underrun in TwoSidedList.firstIndex() or overrun in TwoSidedList.minFreeIndex().

Parameters:

size - the number of elements to be added.

list - the twosided list under consideration.

Throws:

IllegalStateException - if adding size objects to this list would cause underrun in TwoSidedList.firstIndex() or overrun in TwoSidedList.minFreeIndex() depending on this direction.
