10.6@ComponentNameThe following Java code defines the @ComponentName annotation: package org.oasisopen.sca.annotation; import static java.lang.annotation.ElementType.FIELD; import static java.lang.annotation.ElementType.METHOD; import static java.lang.annotation.ElementType.TYPE; import java.lang.annotation.Retention; import java.lang.annotation.Target; @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface ComponentName { } The @ComponentName annotation is used to denote a Java class field or setter method that is used to inject the component name. The following snippet shows a component name field definition sample.
The following snippet shows a component name setter method sample. @ComponentName public void setComponentName(String name) { //… }
The following Java code defines the @Confidentiality annotation: package org.oasisopen.sca.annotation; import static java.lang.annotation.ElementType.FIELD; import static java.lang.annotation.ElementType.METHOD; import static java.lang.annotation.ElementType.PARAMETER; import static java.lang.annotation.ElementType.TYPE; import static java.lang.annotation.RetentionPolicy.RUNTIME; import static org.oasisopen.sca.Constants.SCA_PREFIX; import java.lang.annotation.Inherited; import java.lang.annotation.Retention; import java.lang.annotation.Target; @Inherited @Target({TYPE, FIELD, METHOD, PARAMETER}) @Retention(RUNTIME) @Intent(Confidentiality.CONFIDENTIALITY) public @interface Confidentiality { String CONFIDENTIALITY = SCA_PREFIX + "confidentiality"; String CONFIDENTIALITY_MESSAGE = CONFIDENTIALITY + ".message"; String CONFIDENTIALITY_TRANSPORT = CONFIDENTIALITY + ".transport"; /** * List of confidentiality qualifiers such as "message" or * "transport". * * @return confidentiality qualifiers */ @Qualifier String[] value() default ""; } The @Confidentiality annotation is used to indicate the need for confidentiality. See the SCA Policy Framework Specification [POLICY] for details on the meaning of the intent. See the section on Application of Intent Annotations for samples of how intent annotations are used in Java. 10.8@ConstructorThe following Java code defines the @Constructor annotation: package org.oasisopen.sca.annotation; import static java.lang.annotation.ElementType.CONSTRUCTOR; import static java.lang.annotation.RetentionPolicy.RUNTIME; import java.lang.annotation.Retention; import java.lang.annotation.Target; @Target(CONSTRUCTOR) @Retention(RUNTIME) public @interface Constructor { } The @Constructor annotation is used to mark a particular constructor to use when instantiating a Java component implementation. If a constructor of an implementation class is annotated with @Constructor and the constructor has parameters, each of these parameters MUST have either a @Property annotation or a @Reference annotation. [JCA90003] The following snippet shows a sample for the @Constructor annotation.
@Constructor public HelloServiceImpl(@Property(name="someProperty") String someProperty ){ ... } public String hello(String message) { ... } } 10.9@ContextThe following Java code defines the @Context annotation: package org.oasisopen.sca.annotation; import static java.lang.annotation.ElementType.FIELD; import static java.lang.annotation.ElementType.METHOD; import static java.lang.annotation.RetentionPolicy.RUNTIME; import java.lang.annotation.Retention; import java.lang.annotation.Target; @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface Context { } The @Context annotation is used to denote a Java class field or a setter method that is used to inject a composite context for the component. The type of context to be injected is defined by the type of the Java class field or type of the setter method input argument; the type is either ComponentContext or RequestContext. The @Context annotation has no attributes. The following snippet shows a ComponentContext field definition sample. @Context protected ComponentContext context; The following snippet shows a RequestContext field definition sample. @Context protected RequestContext context; Directory: committees -> download.php download.php -> Emergency Interoperability Consortium Membership Meeting download.php -> Technical Communicators, Get ready: Here comes Augmented Reality!
