Jacob Schmidt 8c0e8144e5 docs: Update documentation links and function references
This commit updates the documentation to reflect the current function names and link structure. Specifically, it addresses the following:

*   Corrected internal links within the documentation to point to the correct markdown files (e.g., `hashDelete.md` instead of `hashDelete`).
*   Updated related function references to reflect the current function names and include missing functions.
*   Removed outdated function references.
*   Added `ramdb_db_fnc_scheduler` to related functions where appropriate.
*   Updated the links section to use the correct markdown file names.

ArmaRAMDb - List Get mdi:file-text-outline Get element of list stored at key from RAMDb.

ramdb_db_fnc_listGet

Description

Retrieves a specific element from a list stored in the database by its index. This function accesses a single item from a list using its position number and returns the data through a callback function. It's useful for accessing individual pieces of data from a sequence without retrieving the entire list.

Syntax

[_key, _index, _function, _call, _netId] call ramdb_db_fnc_listGet

Parameters

Parameter Type Description Default
_key String Name of the list ""
_index Number Index position of the element to retrieve (0-based) -1
_function String Name of the function to receive the retrieved data ""
_call Boolean Whether to call the function directly (true) or spawn (false) false
_netId String (Optional) NetID of the player to receive the data ""

Return Value

None. The retrieved data is passed to the specified callback function asynchronously.

Examples

Retrieve a specific event log entry:

["events", 0, "ramdb_db_fnc_test"] call ramdb_db_fnc_listGet;

Retrieve data with synchronous callback:

["messages", 5, "ramdb_db_fnc_processMessage", true] call ramdb_db_fnc_listGet;

Retrieve data and send it to a specific client:

["notifications", 0, "ramdb_db_fnc_displayNotification", false, netId player] remoteExecCall ["ramdb_db_fnc_listGet", 2, false];

Notes

  • Retrieves a single element from a list by its index position
  • The key, index, and function parameters are required and validated
  • Index is zero-based (the first element is at index 0)
  • If the index is out of bounds or the list doesn't exist, no data will be returned
  • The data is retrieved asynchronously through the extension's callback system
  • When a netId is provided, the data is sent to that specific client
  • The _call parameter determines whether the function is called directly (synchronous) or spawned (asynchronous)
  • For retrieving multiple elements, use listLoad instead
  • All operations are logged for debugging purposes
  • ramdb_db_fnc_listAdd: Adds an element to a list
  • ramdb_db_fnc_listLoad: Retrieves a range of elements from a list
  • ramdb_db_fnc_listSet: Replaces a specific element in a list
  • ramdb_db_fnc_listRemove: Removes a specific element from a list
  • ramdb_db_fnc_listDelete: Deletes an entire list
  • ramdb_db_fnc_scheduler: Processes the callback from the database extension
