Class Browser

java.lang.Object

oracle.rules.sdk2.datamodel.Browser

Direct Known Subclasses:

ClassBrowser, SchemaBrowser

public abstract class Browser
extends java.lang.Object

Browser sub-classes provide browsing of external business objects to be used for rule authoring. The specific sub-classes implement a browswer for a particular type of objects (e.g., Java classes).
Refer to the appropriate sub-class for the operation of browsing a specific type.
All Browser sub-classes use nested NodeTable's to represent the parent child (hierarchial) relationship. among the business objects.
When browsing hierarchal structures (like java classes), the hierachy is represented by nested NodeTable collections. Each successively nested NodeTable is another level in the hierarchy.

Return the dictionary used to create this browser.

getNodeTable

public NodeTable getNodeTable()
                       throws SDKException

Retrieves the NodeTable associated with the set of class paths or schema paths that have been added to this browser instance.
This method refreshes all information about the classes it can reference from its configuration. Therefore, it should only be invoked after the configuration has changed. Changes are typically additions to the class path or schema path. The reference to the NodeTable should be retained if it will be used more than once which is the normal case).
For class browsing, NodeTable will always reflect the java runtime classes if no other java classes or jars have been added to the this instances class path.
For schema browsing, NodeTable will contain the list of JAXB classes that were created when the schema was loaded.
The NodeTable contains the list of nodes visible (by inclusion in the classpath or by opening a node that has children) NodeTable

Throws:

SDKException
