All Implemented Interfaces:

Iterable<Object>, Collection<Object>, List<Object>

final class FixedSizeList
extends AbstractList<Object>

Wraps an array of fixed size. Attempts to add a new element fail when the list reached its maximal capacity. Clearing the array does not set the references to null, since we need to remember the values of previous passes. This implementation is designed for compliance with the part of Moving Features specification saying that "if the value equals the previous value, the text for the value can be omitted".

Field Details

values

private final Object[] values

The array where to store the values. Elements in this array are usually not null even if this list is empty.

size

private int size

Number of elements added in the values array.

clear

public void clear()

Resets the list size to zero, but do not reset the references to null.

get

public Object get(int index)

Returns the value at the given index without check of index validity. We do not bother verifying that index < size because this list is used only for internal purpose.

add

public boolean add(Object value)

Adds the given value if we have not yet reached the maximal capacity of this list.
