Remarks

A command that is keyed by something other than one of its own properties — a composite of two of them, a value derived from them — declares the key itself rather than leaving it to be inferred. This is what a read model backing provider loads the read model by, so it is the same key in every store.

Methods

GetKey()

Gets the key identifying what the command acts on.

string? GetKey()

Returns

string

The key, or null when the command carries nothing to compose one from.
