Public Sub ExecuteCommand(Of T As CommandArgs) (commandHandler As ICommandHandler, args As T, nextCommandHandler As Action, executionContext As CommandExecutionContext)Type Parameters
- T
Parameters
- commandHandler
- ICommandHandler
A command handler to execute the command.
- args
- T
The CommandArgs arguments for the command.
- nextCommandHandler
- Action
The next command handler in the command execution chain.
- executionContext

Current command execution context.
Remarks
A command handler can implement ICommandHandler<T> or IChainedCommandHandler<T>, but either way this method executes the command by either this or next command handler.
If commandHandler implements ICommandHandler<T>, its ExecuteCommand(T, CommandExecutionContext) method is called. If it returns false, nextCommandHandler is invoked.
If commandHandler implements IChainedCommandHandler<T>, its ExecuteCommand(T, Action, CommandExecutionContext) method is invoked with nextCommandHandler passed as an argument.
