isArrayBased()
Checks if implementation is based on Java arrays.
|
boolean |
isDense()
Checks if this implementation should be considered dense so that it explicitly
represents every value.
|
boolean |
isDistributed()
Checks whether implementation is JVM-local or distributed (multi-JVM).
|
boolean |
isRandomAccess()
Checks if this implementation is optimized for random access.
|
boolean |
isSequentialAccess()
Checks if this implementation should be considered to be iterable in index order in an efficient way.
