Economy date

An 
EconomyDate
object is a wrapper for modified and created dates from the economy service. It currently has one parameter as shown below:
  • Date
    : A 
    DateTime
    representation of the wrapped date.

Write lock

The write lock is used to implement optimistic concurrency. It is optional.
A 
writeLock
is returned for each balance or inventory item instance when they are fetched, added or updated. The user can then pass the 
writeLock
value back to the SDK when updating a currency balance or inventory instance. If it matches, the request is successful and will update. If it doesn't, then an error is returned.
The 
writeLock
can be any 
string
value.
For a code example, see the method 
UpdatePlayersInventoryItemUsingWriteLock
in the 
InventoriesBasicExample
sample.
