Cisco Cisco Computer Telephony Integration Option 8.5 Developer's Guide

When running the application, the call to methodA may behave as if it was passed the modified 
Arguments array. This is because many CTI OS methods simply place a pointer to the Arguments array 
on a queue of items to be sent to CTI OS server. When the same Arguments array is later modified, as 
in the preceding example, the pointer on the queue now points to the modified array and the modified 
array is sent to CTI OS server. A problem may occur depending on timing, as there are multiple threads 
involved: the thread pulling items off the queue and the thread modifying the Arguments array. If the 
queued message is sent to CTI OS before the Arguments array is modified, the problem will not occur.

To avoid this problem, call the Clone method on the initial Arguments array and modify the copy rather 
than modifying the original. For example, the preceding example would change as follows:

Programmer passes an Arguments array (initialArray) into a CTI OS SDK method (methodA)

MethodA returns

modifiedArray = initialArray.Clone()

Programmer modifies modifiedArray

Programmer passes the modifiedArray into another CTI OS SDK method (methodB)

The AddItem method expects a key-value pair. The key value may be a string or an integer. The value 
may be a string, an integer, or an object reference. If there is an entry with the same key, it will be 
replaced with this entry, otherwise the new key-value pair will be added to the arguments array. Keys are 
not case sensitive. Leading and trailing spaces are always removed from the key.
