ExternalReferenceDocumentExtensions.ClassIsDerivedFrom Method (CAEXDocument, String, String)

Determines, if the class, specified with the given class path is directly or indirectly (across multiple generations) a descendant of the class, which is uniquely identified with the specified baseClass path. The base class path or the referenced class path may contain alias identifiers. If alias identifiers are present, the method tries to load the externally referenced document. If a referenced document is loaded, it is visible in the ReferencedDocuments enumeration. This method uses the document tables for a fast identification of classes using the caex path

Namespace: AMLEngineExtensions
Assembly: AMLEngineExtensions (in AMLEngineExtensions.dll) Version: 3.5

Syntax

C#

public static Nullable<bool> ClassIsDerivedFrom(
	this CAEXDocument document,
	string classPath,
	string baseClassPath
)

C++

public:
[ExtensionAttribute]
static Nullable<bool> ClassIsDerivedFrom(
	CAEXDocument^ document, 
	String^ classPath, 
	String^ baseClassPath
)

Parameters

 

document
Type: CAEX_ClassModel.CAEXDocument
The document where the classes are searched
classPath
Type: System.String
The class path of the tested class.
baseClassPath
Type: System.String
The base class path.

Return Value

Type: Nullable(Boolean)
true if the class is derived, false if it is not. If no value is returned, some references could not be resolved to get the answer.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type CAEXDocument. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
