/**

* A Packed array of signed 64 bit values, and supports {@link #get get()}, {@link #set set()},

* {@link #add add()} and {@link #increment increment()} operations on the logical contents of the array.
|

|
|
*

|

|
* to complete logical array operations (get, set, add, increment). Contexts are
|

|
|
* established and used within critical sections in order to facilitate concurrent

* implementors.
