public final class ListWithDefault<T> extends Object implements List<T>
List which automatically grows the list when either get(int) or
getAt(int) is called with an index greater than or equal to size().| Modifier and Type | Method and Description |

get(int index)
Returns the element at the given index but grows the list if needed.

getAt(int index)
Overwrites subscript operator handling by redirecting to
get(int). |

public T getAt(int index)
get(int).index - an index (might be greater or equal to size(), or smaller than 0)index or the default valuepublic T get(int index)
index is
greater than or equal to size(), the list will grow to the new size and a default value calculated
using the initClosure will be used to populate the missing value and returned.
If lazyDefaultValues is true any gaps when growing the list are filled
with nulls. Subsequent attempts to retrieve items from the list from those gap index values
will, upon finding null, call the initClosure to populate the list for the
given list value. Hence, when in this mode, nulls cannot be stored in this list.
If lazyDefaultValues is false any gaps when growing the list are filled
eagerly by calling the initClosure for all gap indexes during list growth.
No calls to initClosure are made except during list growth and it is ok to
store null values in the list when in this mode.
This implementation breaks
the contract of List.get(int) as it a) possibly modifies the underlying list and b) does
NOT throw an IndexOutOfBoundsException when index < 0 || index >= size().
