Examples of CommandService

org.apache.isis.applib.services.command.spi.CommandService
Intended for service to implement, providing a different implementation of {@link Command}.
The default implementation (provided automatically by the framework) will instantiate an in-memory implementation of {@link Command}. However, other services (eg as provided by the JDO objectstore) might provide a persistable {@link Command} object.
org.drools.command.CommandService
org.drools.core.command.CommandService
org.drools.process.command.CommandService
org.eclipse.ui.internal.commands.CommandService

Provides services related to the command architecture within the workbench. This service can be used to access the set of commands and handlers.

org.geomajas.puregwt.client.command.CommandService
Central service for executing commands. These commands are sent to the server for execution. This command pattern uses the GWT RPC system as protocol. @author Pieter De Graef @author Jan De Moerloose @since 1.0.0

org.jbpm.client.CommandService
abstract extensible session facade. Developers can use this directly or extend one of the implementations with custom methods. Developers should be encouraged to use this interface as it will be kept more stable then direct usage of the API (which is still allowed). All the method implementations should be based on commands. Each of the method implementations will have a environment block. Then the command is executed and the environment is passed into the command.

org.rhq.enterprise.communications.command.server.CommandService
The superclass for all command services. Command services are providers of {@link CommandType command types} - thatis, they support the invocation of one or more {@link Command commands}.
Extending this class gives all command services the same interface, which is how the {@link CommandProcessor} canbe extended to execute arbitrary commands.

All command services are registered with the {@link CommandServiceDirectoryMBean command service directory}, which allows the command processor to find this service and its supported commands easily.

Note that subclasses do not need define their own MBean interface; they need only inherit this service's MBean interface in order to plug into the command processor infrastructure.

This class is typically used to process requests of the same kind of command, or perhaps different versions of the same kind of command. To facilitate easier support for multiple commands, see {@link MultipleCommandService}. Use that class if a command service expects to process many different kinds of commands. That is not to say direct subclasses of this class cannot support multiple commands - they can. However, it typically will involve the execute method containing a series of if-then-else statements to check the instanceof value of the incoming {@link Command} object.
