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 * Removed outdated function references.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.

# ramdb_db_fnc_hashGet
|
|
|
|
## Description
|
|
Retrieves the value associated with a specific field in the hash table of the current client/player. This function automatically determines the appropriate hash ID based on the caller's identity, making it more convenient than `hashGetId` which requires manually specifying an ID. It accesses hash data asynchronously and returns the result through a callback function.
|
|
|
|
## Syntax
|
|
```sqf
|
|
[_keyField, _function, _call, _netId] call ramdb_db_fnc_hashGet
|
|
```
|
|
|
|
## Parameters
|
|
| Parameter | Type | Description | Default |
|
|
|-------------|---------|------------------------------------------------------------|---------|
|
|
| `_keyField` | String | Name of the field in the hash to retrieve | "" |
|
|
| `_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 player's loadout:
|
|
```sqf
|
|
["loadout", "ramdb_db_fnc_test"] call ramdb_db_fnc_hashGet;
|
|
```
|
|
|
|
### Retrieve data with synchronous callback:
|
|
```sqf
|
|
["playerScore", "ramdb_db_fnc_processScore", true] call ramdb_db_fnc_hashGet;
|
|
```
|
|
|
|
### Retrieve data and send it to a specific client:
|
|
```sqf
|
|
["loadout", "ramdb_db_fnc_test", false, netId player] remoteExecCall ["ramdb_db_fnc_hashGet", 2, false];
|
|
```
|
|
|
|
## Notes
|
|
- Retrieves a value from the current client's hash table
|
|
- The data is retrieved asynchronously through the extension's callback system
|
|
- Both the field name and callback function name must be provided
|
|
- Input validation ensures both required parameters are non-empty
|
|
- 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)
|
|
- This function automatically determines which hash table to use based on the caller's identity
|
|
- Use `hashGetId` when you need to specify a particular hash table by ID
|
|
- All operations are logged for debugging purposes
|
