Remarks

The rule Arc ships is asked last regardless of the order the rules are discovered in, so an application's own rule always decides and the outcome never depends on discovery order.

Constructors

CommandKeys(IInstancesOf<ICanResolveKeyForCommand>)

Represents an implementation of ICommandKeys that asks each ICanResolveKeyForCommand in turn.

public CommandKeys(IInstancesOf<ICanResolveKeyForCommand> resolvers)

Parameters

resolvers IInstancesOf<ICanResolveKeyForCommand>

The rules for reading a key from a command.

Remarks

The rule Arc ships is asked last regardless of the order the rules are discovered in, so an application's own rule always decides and the outcome never depends on discovery order.

Methods

GetKeyFor(object)

Gets the key a command identifies its target by.

public string? GetKeyFor(object command)

Parameters

command object

The command to read.

Returns

string

The key, or null when no rule recognizes one on the command.
