Detailed Description

Singleton registry for global blackboard variable presets.

Loaded from Assets/Config/BlackboardVariablePresets.json at editor startup. Provides O(1) lookup by name via internal index map. Category queries are O(n) on the preset list but cached on first access.

Thread-safety: read-only after LoadFromFile() — no locking required.

(

const std::string &

category

)

const

Returns all presets belonging to a given category.

Parameters

category

Category label to filter by (case-sensitive).

Returns

Vector of matching presets (may be empty).

GetPreset()

const BlackboardVariablePreset * Olympe::BlackboardVariablePresetRegistry::GetPreset

(

const std::string &

name

)

const

Returns a pointer to the preset with the given name, or nullptr.

Parameters

name	Variable name to look up (case-sensitive).

Returns

Pointer to preset if found, nullptr otherwise.

Clears any previously loaded data before loading. On parse error, logs and returns false; registry remains empty.

Parameters

filePath

Absolute or relative path to the JSON preset file.

Returns

true on success, false on file/parse error.
