Package com.orchestranetworks.userservice.declaration

Interface UserServiceDeclaration<S extends EntitySelection,U extends ActivationContext<S>>

Type Parameters:

S - the nature of the service, namely the type of the selection on which the service works

U - the activation context corresponding to the nature of the service

All Known Subinterfaces:

UserServiceDeclaration.OnAssociation, UserServiceDeclaration.OnAssociationRecord, UserServiceDeclaration.OnDataset, UserServiceDeclaration.OnDataspace, UserServiceDeclaration.OnHierarchy, UserServiceDeclaration.OnHierarchyNode, UserServiceDeclaration.OnRecord, UserServiceDeclaration.OnTableView

public interface UserServiceDeclaration<S extends EntitySelection,U extends ActivationContext<S>>

This interface allows to declare a user service. It must not be implemented directly; instead, one of the nested sub-interfaces must be implemented according to the nature of the user service to declare.

A user service can be registered and declared either in the context of a data model or in the context of a module.

Since:

5.8.0

Method Summary

Modifier and Type	Method	Description
default UserService<S>	createUserService()	Creates a new user service implementation.
void	declareWebComponent(WebComponentDeclarationContext aContext)	Defines the web component properties of the user service, in particular its input and output parameters, and whether it can be available as a perspective action and/or workflow user task.
void	defineActivation(U aContext)	Defines the activation scope and rules of the service, namely where and when it is available and can be executed.
void	defineProperties(UserServicePropertiesDefinitionContext aContext)	Defines the properties of the user service, in particular its label and description.
ServiceKey	getServiceKey()	Returns the identifier of the user service.

Method Details

getServiceKey

ServiceKey getServiceKey()

Returns the identifier of the user service.

The returned ServiceKey must conform to the current declaration context; for example, if the service is being declared in the context of a module its key must contain the current module name.

This method is invoked only once, when the user service is registered.

It is generally recommended to define a public Java constant holding the service key.

createUserService

default UserService<S> createUserService()

Creates a new user service implementation. It is strongly unadvised to return a user service with no parameter.

This method is invoked every time the declared user service must be launched, once all activation controls have been performed.

defineActivation

void defineActivation(U aContext)

Defines the activation scope and rules of the service, namely where and when it is available and can be executed.

This method is invoked only once, when the user service is registered.

defineProperties

void defineProperties(UserServicePropertiesDefinitionContext aContext)

Defines the properties of the user service, in particular its label and description.

This method is invoked only once, when the user service is registered.

declareWebComponent

void declareWebComponent(WebComponentDeclarationContext aContext)

Defines the web component properties of the user service, in particular its input and output parameters, and whether it can be available as a perspective action and/or workflow user task.

This method is invoked only once, when the user service is registered.
