org.nuxeo.connect.update.task.standalone.commands

Class AbstractCommand

java.lang.Object

org.nuxeo.connect.update.task.standalone.commands.AbstractCommand

All Implemented Interfaces:

org.nuxeo.connect.update.task.Command

Direct Known Subclasses:

CompositeCommand, Config, Copy, Delete, DeployConfigPlaceholder, DeployPlaceholder, InstallPlaceholder, LoadJarPlaceholder, PostInstallCommand, Rollback, UnAppend, UndeployConfigPlaceholder, UndeployPlaceholder, UninstallPlaceholder, UnloadJarPlaceholder, Update

public abstract class AbstractCommand
extends Object
implements org.nuxeo.connect.update.task.Command

All commands have 2 attributes: fail and ignore which are EL expressions.

If ignore is defined and evaluated to true then the command will be ignored (null is returned as the inverse command) If fail is defined and evaluated to true then the validation fails.

Commands extending this class must implement the doRun(org.nuxeo.connect.update.task.Task, java.util.Map<java.lang.String, java.lang.String>) and doValidate(org.nuxeo.connect.update.task.Task, org.nuxeo.connect.update.ValidationStatus) methods instead of the one in the interface. These methods are first testing for ignore and fail guards and then if needed delegated to the doXXX method versions.
