javax.management.relation
Class RelationTypeSupport

java.lang.Object
  javax.management.relation.RelationTypeSupport

All Implemented Interfaces:

Serializable, RelationType

---

public class RelationTypeSupport
extends Object
implements RelationType

A RelationTypeSupport object implements the RelationType interface.

It represents a relation type, providing role information for each role expected to be supported in every relation of that type.

A relation type includes a relation type name and a list of role infos (represented by RoleInfo objects).

A relation type has to be declared in the Relation Service:

- either using the createRelationType() method, where a RelationTypeSupport object will be created and kept in the Relation Service

- either using the addRelationType() method where the user has to create an object implementing the RelationType interface, and this object will be used as representing a relation type in the Relation Service.

Since:

1.5

Constructor Detail

RelationTypeSupport

public RelationTypeSupport(String theRelTypeName,
                           RoleInfo[] theRoleInfoArray)
                    throws IllegalArgumentException,
                           InvalidRelationTypeException

Constructor where all role definitions are dynamically created and passed as parameter.

Parameters:

theRelTypeName - Name of relation type

theRoleInfoArray - List of role definitions (RoleInfo objects)

Throws:

IllegalArgumentException - if null parameter

InvalidRelationTypeException - if:

- the same name has been used for two different roles

- no role info provided

- one null role info provided

---

RelationTypeSupport

protected RelationTypeSupport(String theRelTypeName)

Constructor to be used for subclasses.

Parameters:

theRelTypeName - Name of relation type.

Throws:

IllegalArgumentException - if null parameter.

Method Detail

getRelationTypeName

public String getRelationTypeName()

Returns the relation type name.

Specified by:

getRelationTypeName in interface RelationType

Returns:

the relation type name.

---

getRoleInfos

public List getRoleInfos()

Returns the list of role definitions (ArrayList of RoleInfo objects).

Specified by:

getRoleInfos in interface RelationType

Returns:

an ArrayList of RoleInfo.

---

getRoleInfo

public RoleInfo getRoleInfo(String theRoleInfoName)
                     throws IllegalArgumentException,
                            RoleInfoNotFoundException

Returns the role info (RoleInfo object) for the given role info name (null if not found).

Specified by:

getRoleInfo in interface RelationType

Parameters:

theRoleInfoName - role info name

Returns:

RoleInfo object providing role definition does not exist

Throws:

IllegalArgumentException - if null parameter

RoleInfoNotFoundException - if no role info with that name in relation type.

---

addRoleInfo

protected void addRoleInfo(RoleInfo theRoleInfo)
                    throws IllegalArgumentException,
                           InvalidRelationTypeException

Add a role info. This method of course should not be used after the creation of the relation type, because updating it would invalidate that the relations created associated to that type still conform to it. Can throw a RuntimeException if trying to update a relation type declared in the Relation Service.

Parameters:

theRoleInfo - role info to be added.

Throws:

IllegalArgumentException - if null parameter.

InvalidRelationTypeException - if there is already a role info in current relation type with the same name.
