equal to the key argument.
|
boolean |
hasGreaterOrEqual(K key,

argument, yet with a value greater than or equal to the value argument
provided.
|
boolean |
hasLessOrEqual(K key)

equal to the key argument.
|
boolean |
hasLessOrEqual(K key,
V val)
Checks to see if this table has a Tuple with a key equal to the key
argument, yet with a value less than or equal to the value argument
provided.
|
boolean |
isDupsEnabled()
Checks to see if this Table has allows for duplicate keys (a.k.a.
|
long |
lessThanCount(K key)
Gets the number of records less than or equal to a key value.
|
