Class Auditor

java.lang.Object
oracle.jdeveloper.audit.service.Auditor

Direct Known Subclasses:

DefaultAuditor

public abstract class Auditor

extends java.lang.Object

The executor of an audit over a particular set of constructs using a particular profile. The profile supplies the analyzers for the audit and is set by setProfile(oracle.jdeveloper.audit.service.Profile). The constructs audited are those added to this auditor by addElement(oracle.ide.model.Element, oracle.ide.model.Node, oracle.ide.model.Project, oracle.ide.model.Workspace), and/or addConstruct(java.lang.Object, java.net.URL, oracle.ide.model.Project, oracle.ide.model.Workspace). The audit is executed by run(), which invokes the visitor methods of the analyzers and delivers the results they produce to the listeners registered with addAuditListener(oracle.jdeveloper.audit.service.AuditListener). When the results are no longer needed, resources held by the auditor are released by clear().

An auditor can be reused: locations to be audited can be added and removed.

Method Detail

addAuditListener

public abstract void addAuditListener(AuditListener listener)

isAuditable

public abstract boolean isAuditable(Element element,
                                    Node node,
                                    Project project,
                                    Workspace workspace)

Gets whether an Element is auditable. An element is auditable if is of an auditable type, and if the context represented by the node, project, workspace is adequate.

If the workspace is not null, it must be open; if the project is not null, it must be open; if the node is not null, it must be open. Since this is a new stipulation, only a warning is logged currently.

Parameters:

element - An Element corresponding to a construct in the Audit object model.

node - The Node containing the element. Ignored if element is a node.

project - The project containing the element. Ignored if element is a Workspace or Project.

workspace - The workspace containing the element. Ignored if element is a Workspace.

addElement

public abstract boolean addElement(Element element,
                                   Node node,
                                   Project project,
                                   Workspace workspace)

Adds the location corresponding to an Element to the set of locations to be audited. The location will not be added if the element is not auditable.

If the workspace is not null, it must be open; if the project is not null, it must be open; if the node is not null, it must be open. Since this is a new stipulation, only a warning is logged currently.

Parameters:

element - An Element corresponding to a construct in the Audit object model.

node - The Node containing the element. Ignored if element is a node.

project - The project containing the element. Ignored if element is a Workspace or Project.

workspace - The workspace containing the element. Ignored if element is a Workspace.

Returns:

True if the location was added.

                                    Workspace workspace)

Adds the locations corresponding to an array of Elements in a Node to the set of locations to be audited. Locations for elements which are not auditable will not be added.

If the workspace is not null, it must be open; if the project is not null, it must be open; if the node is not null, it must be open. Since this is a new stipulation, only a warning is logged currently.

Parameters:

                                Project project,
                                Workspace workspace)

Adds the location corresponding to a Node to the set of locations to be audited. The location will not be added if the project is null, unless the node is a project or workspace; or if the workspace is null, unless the node is a workspace.

If the workspace is not null, it must be open; if the project is not null, it must be open. Since this is a new stipulation, only a warning is logged currently.

Parameters:

                                     Project project,
                                     Workspace workspace)

Adds the location corresponding to a construct to the set of locations to be audited. The location will not be added if the file, project, or workspace are null.

The workspace and project must be open. Since this is a new stipulation, only a warning is logged currently.

Parameters:

construct - A construct in the Audit object model (e.g., a Java object).

file - The URL of the file containing the construct.

project - The project containing the file.

workspace - The workspace containing the file.

Returns:

True if the location was added.

                               Project project,
                               Workspace workspace)

Adds the location corresponding to a URL to the set of locations to be audited. The location will not be added if the project is null, unless the node is a project or workspace; or if the workspace is null, unless the node is a workspace. If the workspace is not null and not open, it will be opened. If the project is not null and not open, it will be scanned for technologies and the associated extensions will be loaded.

Parameters:

url - The URL of a file or directory in the Audit object model.

project - The project containing the file.

workspace - The workspace containing the file.

Returns:

True if the location was added.

isAuditableType

                                  java.lang.Object value)

Sets a configuration attribute for this auditor. Configuration attributes are accessible to model adapters through the ModelFactory.getAttribute method and to analyzers through the AuditContext.getAttribute(oracle.jdeveloper.audit.analyzer.AuditContext.Key) method with a AuditContext.sharedKey(java.lang.Object)

Typically, configuration attributes are used to allow an IDE command that is implemented using Audit to provide command-specific attributes to a model adapter or analyzer.

Parameters:

key - An object, typically a java.lang.Class, which uniquely identifies the attribute, used to create the shared key.

value - The possibly null value of the attribute.

Throws:

java.lang.IllegalStateException - if locations to be audited have already been added.
