Members

executeCommand(InteractionContextPolicy, Command)

Executes the specified Command using the required InteractionContextPolicy , updating the Command (or its persistent equivalent) afterwards (for example, setting its Command#getCommandDto() commandDto field.

executeCommand(InteractionContextPolicy, CommandDto)

Executes the specified command (represented as a CommandDto using the required InteractionContextPolicy .

THIS METHOD HAS SIGNIFICANT SIDE-EFFECTS. Specifically, the Command of the executing thread (obtained using org.apache.causeway.applib.services.iactn.InteractionProvider to obtain the Interaction , and then Interaction#getCommand() to obtain the Command ) will be UPDATED to hold the CommandDto passed in.

executeCommand(Command)

As per #executeCommand(InteractionContextPolicy, Command) , with a policy of InteractionContextPolicy#NO_SWITCH no switch .

Note that this method updates the Command as a side-effect.

executeCommand(CommandDto)

As per #executeCommand(InteractionContextPolicy, CommandDto) , with a policy of InteractionContextPolicy#NO_SWITCH no switch .

THIS METHOD HAS SIGNIFICANT SIDE-EFFECTS. Specifically, the Command of the executing thread (obtained using org.apache.causeway.applib.services.iactn.InteractionProvider to obtain the Interaction , and then Interaction#getCommand() to obtain the Command ) will be UPDATED to hold the CommandDto passed in.

Implementation

The framework provides a default implementation of this service, o.a.i.core.runtimeservices.command.CommandExecutorServiceDefault

Usage

The CommandExecutorService domain service is provides the ability to execute a specified Command, optionally running the command with the identity of the user captured in that Command.
