|
|
* DESCRIPTION: Store the object to the named object.
|
|
*
|
|
* The Assignment of an object to a named object is handled here
|
|
* The val passed in will replace the current value (if any)
|
|
* with the input value.
|
|
*
|
|
* When storing into an object the data is converted to the
|
|
* target object type then stored in the object. This means
|
|
* that the target object type (for an initialized target) will
|
|
* not be changed by a store operation.
|
|
*
|
|
* NOTE: the global lock is acquired early. This will result
|
|
* in the global lock being held a bit longer. Also, if the
|
|
* function fails during set up we may get the lock when we
|
|
* don't really need it. I don't think we care.
