State Reads/Writes
State Reads and Writes from objects may be only be done by the current actor using the following system calls:
actor_open_field
actor_open_key_value_entry
actor_index_insert
actor_index_remove
actor_index_scan_keys
actor_index_drain
actor_sorted_index_insert
actor_sorted_index_remove
actor_sorted_index_scan
Key Value Stores are a special type of object though which may be read/written to as long as one has a reference to that key value store. This is accessible via the system call:
key_value_store_open_entry
