Finding Objects by Type

To find all objects of a specified type, specify only the first argument of the BusinessQueryManagerImpl.findObjects method and, optionally, a collection of FindQualifier objects. For example, if typeString is a string whose value is LifeCycleManager.SERVICE, the following code fragment finds all services in the Registry and sorts them in alphabetical order.

Collection findQualifiers = new ArrayList();
findQualifiers.add(FindQualifier.SORT_BY_NAME_ASC);

BulkResponse response = bqm.findObjects(typeString,
     findQualifiers, null, null, null, null, null);

You cannot use wildcards in the first argument to findObjects.

Finding Objects by Type: Example

For an example of finding objects by type, see JAXRSearchByObjectType.java in the directory INSTALL/registry-samples/search-object-type/src.

To Run the JAXRSearchByObjectType Example

1. Go to the directory INSTALL/registry-samples/search-object-type.

2. Type the following command, specifying a string value:

   Ant-base/ant run -Dtype=type-name

   Specify the exact name of the type, not a wildcard, as in the following command line:

   Ant-base/ant run -Dtype=federation

   The JAXRSearchByObjectType program passes the object type as a string argument to QueryManager.findObjects in order to accept user input as simply as possible. However, developers should use the constants defined by the LifeCycleManager interface.

   The program performs a case-insensitive search, returning all objects whose type is type-nameand displaying their names, descriptions, and unique identifiers. At the end, it displays the number of objects found.
