public interface Size64

An interface for data structures whose size can exceed Integer.MAX_VALUE.

The only methods specified by this interfaces are size64(), and a deprecated size() identical to Collection.size(), but with a default implementation. Implementations can work around the type problem of Collection.size() (e.g., not being able to return more than Integer.MAX_VALUE) by implementing this interface. Callers interested in large structures can use a reflective call to instanceof to check for the presence of size64().

Method Summary

Modifier and Type	Method and Description
default int	size() Deprecated. Use size64() instead.
long	size64() Returns the size of this data structure as a long.

Method Detail

size64

long size64()

Returns the size of this data structure as a long.

Returns:

the size of this data structure.

size

@Deprecated
default int size()

Deprecated. Use size64() instead.

Returns the size of this data structure, minimized with Integer.MAX_VALUE.

This default implementation follows the definition above, which is compatible with Collection.size().

Returns:

the size of this data structure, minimized with Integer.MAX_VALUE.
