Struct InitializationSlot

A strongly-typed bitmask representing a single aspect behavior slot for cross-layer coordination. Each aspect type that needs coordination allocates one slot at class initialization time.

Namespace: Metalama.Framework.RunTime.Initialization

Assembly: Metalama.Framework.dll

Syntax

public readonly struct InitializationSlot

Remarks

Slots are needed only by aspect types that address the telescoping constructor problem — i.e., aspects whose Initialize(InitializationContext) behavior must be skipped when a derived type guarantees it will handle the same concern.

A maximum of 32 slots can be allocated per Metalama.Framework.RunTime.Initialization.InitializationSlotFactory (or per AppDomain when using the default factory via Allocate()). In practice, very few aspect types need slots (likely fewer than half a dozen in a typical application).

Properties

Name	Description
OnConstructed	Slot used by the engine's `OnConstructed` mechanism to coordinate multi-level inheritance. Derived constructors descend their context with this slot before calling the base constructor; base constructors guard the `OnConstructed` call with IsHandled(InitializationSlot) against this slot. Not intended for direct use by aspects.

Methods

Name	Description
Allocate()	Allocates a new slot from the default global factory. Maximum 32 slots per AppDomain.

Operators

Name	Description
operator \|(InitializationSlot, InitializationSlot)	Combines two slots into one.
