Package com.ibm.websphere.command
Provides the interfaces and classes for caching command objects.
See:
Interface Summary
| Interface | Description |
|---|---|
| CacheableCommand | The CacheableCommand interface provides the contract between the client and the command implementation for those commands that participate in the command caching framework. |
| Command | The Command interface defines the client side for fundamental command functionality. |
| CommandCaller | This interface allows the caller of a command to have additional invalidation dependencies added by this command. |
| CommandIdGenerator | The CommandIdGenerator is responsible for generating cache entry ids and data ids, and invalidating data ids for command objects. |
| CommandTarget | The CommandTarget interface describes the object that handles the execution of a targetable command. |
| CompensableCommand | The CompensableCommand interface allows you to make a command reversible. |
| TargetableCommand | The TargetableCommand interface describes a command that can be run in a remote JVM. |
| TargetPolicy | The TargetPolicy interface declares one method, getCommandTarget(), which implements the routine used to associate commands and targets. |
Class Summary
| Class | Description |
|---|---|
| CacheableCommandImpl | This CacheableCommandImpl abstract class provides an implementation for all CacheableCommand interface methods except those that the command writer must write. |
| LocalTarget | The LocalTarget class provides an implementation of the CommandTarget interface. |
| TargetableCommandImpl | The TargetableCommandImpl class implements the generic methods in the TargetableCommand interface. |
| TargetPolicyDefault | The TargetPolicyDefault class provides an implementation of the TargetPolicy interface. |
Exception Summary
| Exception | Description |
|---|---|
| CommandException | This is the base class for all Command exceptions. |
| UnauthorizedAccessException | UnauthorizedAccessException is thrown when attempting to execute a command without access authorization. |
| UnavailableCompensatingCommandException | UnavailableCompensableCommandException is thrown by the getCompensatingCommand() method (in the CompensableCommand interface) if it finds no compensating command to return. |
| UnsetInputPropertiesException | UnsetInputPropertiesException is thrown by the execute() method
(in a TargetableCommandImpl class) if a command's isReadyToCallExecute()
method returns false. |
