public interface CodeElement2 : CodeElement

NameDescription
System_CAPS_pubpropertyChildren

Gets a collection of objects contained within this CodeElement2.

System_CAPS_pubpropertyCollection

Gets the CodeElements collection containing the CodeElement2 that supports this property.

System_CAPS_pubpropertyDTE

Gets the top-level extensibility object.

System_CAPS_pubpropertyElementID

Gets a value that uniquely identifies the element. Not implemented in Visual C#.

System_CAPS_pubpropertyEndPoint

Gets the text point that is the location of the end of the code item.

System_CAPS_pubpropertyExtender[String]

Returns the requested Extender if it is available for this CodeElement2 object. Not implemented in Visual C#.

System_CAPS_pubpropertyExtenderCATID

Gets the Extender category ID (CATID) for the CodeElement2 object. Not implemented in Visual C#.

System_CAPS_pubpropertyExtenderNames

Gets a list of available Extenders for the CodeElement2 object. Not implemented in Visual C#.

System_CAPS_pubpropertyFullName

Gets the full path and name of the CodeElement2 object's file.

System_CAPS_pubpropertyInfoLocation

Gets the capabilities of the code model.

System_CAPS_pubpropertyIsCodeType

Gets whether or not a CodeType object can be obtained from the CodeElement2 object.

System_CAPS_pubpropertyKind

Gets an enumeration that defines the type of code element.

System_CAPS_pubpropertyLanguage

Gets the programming language that is used to author the CodeElement2.

System_CAPS_pubpropertyName

Gets or sets the name of the CodeElement2 object.

System_CAPS_pubpropertyProjectItem

Gets the ProjectItem object associated with the CodeElement object.

System_CAPS_pubpropertyStartPoint

Gets a TextPoint object that defines the beginning of the CodeElement2.

NameDescription
System_CAPS_pubmethodGetEndPoint(vsCMPart)

Gets a TextPoint object that marks the end of the code element definition.

System_CAPS_pubmethodGetStartPoint(vsCMPart)

Gets a TextPoint object that marks the beginning of the code element definition.

System_CAPS_pubmethodRenameSymbol(String)

Changes the declared name of an object and updates all code references to the object within the scope of the current project.

A code element can be any fragment of code, but generally, there is a CodeElement2 object for each definition or declarative syntax in a language. This means that for most top-level definitions or declarations in a file, or for any syntactic form in a class definition, and so forth, there is a corresponding CodeElement2 object.

System_CAPS_noteNote

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).
