Pasting in the Access Key. For example you can read a csv file, add fields (for example a calculated field based on values of other fields) to the objects and then add all of those to a new (empty) collection which you can then write to a csv again or process further. This technique is fast because the key function is called exactly once for each input record. However, if the specified key already exists in the Hashtable , setting the Item[Object] property overwrites the old value. Delegating query cache that can also perform exception translation for use in facades. If the key was already associated with a JSONArray, then the value parameter is appended to it.

It includes a new value on a pre-existing key within a FormData object. The output array will be ordered by keys. The point is that if you have a JSON Array (or an Array of like Objects) and have to search for a key value on an Object inside that Array (more than once), it is far more efficient to create a map of the key or keys you wish to search on, than to search the Array each time.
