GeoTiffStore

private final class GeoTiffStore.Components
extends ListOfUnknownSize<GridCoverageResource>

The components returned by GeoTiffStore.components. Defined as a named class instead of an anonymous class for more readable stack trace. This is especially useful since BackingStoreException may happen in any method.

Specified by:

size in interface Collection<GridCoverageResource>

Specified by:

size in interface List<GridCoverageResource>

Overrides:

size in class ListOfUnknownSize<GridCoverageResource>

Returns:

the number of elements in this list.

exists

protected boolean exists(int index)

Returns whether the given index is valid.

Specified by:

exists in class ListOfUnknownSize<GridCoverageResource>

Parameters:

index - the index where to verify if an element exists.

get

public GridCoverageResource get(int index)

Returns element at the given index or throw IndexOutOfBoundsException.

Specified by:

get in interface List<GridCoverageResource>

Specified by:

get in class ListOfUnknownSize<GridCoverageResource>

Parameters:

index - position of the element to get in this list.
