Defining Multiple Object Types on One Class

In annotation style, you can use one Java class to model two or more managed object types.

Procedure

Annotate the class as @TeaObjectTypes, and include within it a separate @TeaObjectType annotation for each of the object types that the class can represent.

For example,

@TeaObjectTypes({
    @TeaObjectType(name = "TOMCAT_SERVER",
        concept = TeaConcept.PROCESS,
        description = "Tomcat Server"),
    @TeaObjectType(name = "TOMCAT_WEBAPP",
        concept = TeaConcept.APPLICATION,
        description = "Tomcat Web Application") })
public class TomcatServerManager {
    ...
}

For each object type, define a method that translates from an object key to basic information about the object, and annotate that method as @TeaGetInfo. You must include the objectType attribute in the annotation, to distinguish the object type to which each such method applies.

@TeaObjectTypes({
    @TeaObjectType(name = "TOMCAT_SERVER",
        concept = TeaConcept.PROCESS,
        description = "Tomcat Server"),
    @TeaObjectType(name = "TOMCAT_WEBAPP",
        concept = TeaConcept.APPLICATION,
        description = "Tomcat Web Application") })
public class TomcatServerManager {
 
    @TeaGetInfo(objectType = "TOMCAT_SERVER")
    AgentObjectInfo getServerInfo(String key) {
        ...
    }
 
    @TeaGetInfo(objectType = "TOMCAT_WEBAPP")
    AgentObjectInfo getWebappInfo(String key) {
        ...
    }
}

Similarly, include the objectType attribute when modeling aspects such as state, configuration, members, operations and references.
