Method Detail

createSequence

protected abstract E createSequence(AttributeStorage storage,
                                    int size)

Creates a sequence object with certain size.

Parameters:

storage - attribute storage

size - the sequence size

set

protected abstract void set(AttributeStorage storage,
                            E sequence,
                            Object component)

Stores an element into the sequence.

Parameters:

storage - attribute storage.

sequence - sequence object.

component - sequence element.

next

protected abstract boolean next(AttributeStorage storage,
                                E sequence)

Moves to next sequence element and makes it current. Returns true, if there is next elements in sequence, or false otherwise.

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

true, if there is next elements in sequence, or false otherwise.

size

protected abstract int size(AttributeStorage storage,
                            E sequence)

Returns the size of the sequence.

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

the size of the sequence.

initialize
