Field Detail

list

public Nod[] list

Items.

size

public int size

Size.

Constructor Detail

NodIter

public NodIter()

Constructor.

NodIter

public NodIter(boolean d)

Constructor.

Parameters:

d - returns if the iterator might return duplicates

Method Detail

delete

public void delete(int p)

Deletes a value at the specified position.

Parameters:

p - deletion position

add

public void add(Nod n)

Adds a node.

Parameters:

n - node to be added

reset

public boolean reset()

Description copied from class: Iter

Resets the iterator and returns true. Note: false is returned if the iterator cannot be reset, so the returned value has to be checked.

Overrides:

reset in class Iter

Returns:

true if operator could be reset

next

public Nod next()

Description copied from class: Iter

Returns the next item or null if no other items are found.

Specified by:

next in class NodeIter

Returns:

resulting item

get

public Item get(long i)

Description copied from class: Iter

Returns the specified item. Note: null is returned if the item cannot be retrieved, so the returned value has to be checked.

Overrides:

get in class Iter

Parameters:

i - value offset

Returns:

specified item

size

public int size()

Description copied from class: Iter

Returns the number of entries. Note: -1 is returned if the number cannot be retrieved, so the returned value has to be checked. If this method is implemented, Iter.get(long) has to be implemented as well.

Overrides:

size in class Iter

Returns:

number of entries

finish

public Item finish()

Description copied from class: Iter

Returns a sequence from all iterator values. Should be called before Iter.next().

Overrides:

finish in class Iter

Returns:

sequence

sort

public void sort(boolean force)

Sorts the nodes.

Parameters:

force - force sort

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
