Class DiplomacyTreatyManager

Namespace

Core.Diplomacy

Assembly

Core.dll

ENGINE LAYER - Manages treaties between countries

RESPONSIBILITY:

• Treaty queries (AreAllied, HasNonAggressionPact, IsGuaranteeing, HasMilitaryAccess)
• Treaty state changes (Form/Break Alliance, NAP, Guarantee, Military Access)
• Treaty relationship queries (GetAllies, GetAlliesRecursive, GetGuaranteeing, GetGuaranteedBy)

PATTERN: Stateless manager (receives data references from DiplomacySystem)

• Does NOT own NativeCollections (passed as parameters)
• Uses RelationData.treatyFlags bitfield for treaty storage
• Directional treaties (Guarantee, Military Access) use separate bits for each direction

PERFORMANCE:

• Treaty checks: O(1) dictionary lookup + bitfield check
• GetAllies: O(n) where n = total relationships
• GetAlliesRecursive: O(n) BFS traversal
