Méthodes publiques

Méthode	Description
AddChild ( AddressSpaceElement aChild ) : bool	Adds a namespace element as child to the root element
GetChildren ( ) : ArrayList	Returns the collection of root children
GetParent ( ) : AddressSpaceElement	returns the parent of the root - this is not usefull, but kept for compatibility with the element interface
QueryAddressSpaceElementChildren ( string anElementID, ArrayList aChildrenList ) : int	Returns the collection of children of the address space element to the element ID provided. This interface needs to be implemented in the string based object space case
QueryAddressSpaceElementData ( string anElementID, AddressSpaceElement &anElement ) : int	Returns the corresponding address space element to the element ID provided. This interface needs to be implemented in the string based object space case.
QueryAddressSpaceElementDataEx ( string anElementID, EnumAddressSpaceElementData &elementDataFilter, AddressSpaceElement &anElement ) : int	Returns the corresponding address space element to the element ID provided. This interface needs to be implemented in the string based object space case. This is the extended version of QueryAddressSpaceElementData method.
RemoveChild ( AddressSpaceElement aChild ) : bool	Removes Child and its children if there are some

RemoveElementFromArray ( AddressSpaceElement anElement ) : int	removes an element from the internal hashtable
RemoveElementFromArray ( uint anElementUserData ) : int	removes an element from the internal hashtable

Method Details

AddChild() public méthode

Adds a namespace element as child to the root element

public AddChild ( AddressSpaceElement aChild ) : bool
aChild	AddressSpaceElement	Child to be added
Résultat	bool

AddressSpaceRoot() protected méthode

Used to build an address space toor both object and string based

protected AddressSpaceRoot ( AddressSpaceElement aRoot ) : System
aRoot	AddressSpaceElement	An address space element to impersonate the root. This element is not visible in the namespace
Résultat	System

AddressSpaceRoot() protected méthode

AddressSpaceRoot constructor: Used to build a specialised root type

protected AddressSpaceRoot ( EnumAddressSpaceType anAddressSpaceType, AddressSpaceElement aRoot ) : System
anAddressSpaceType	EnumAddressSpaceType	/// The type of address space ///
aRoot	AddressSpaceElement	/// An address space element to impersonate the root. This element is not visible in the namespace ///
Résultat	System

GetChildren() public méthode

Returns the collection of root children

public GetChildren ( ) : ArrayList
Résultat	ArrayList

GetParent() public méthode

returns the parent of the root - this is not usefull, but kept for compatibility with the element interface

public GetParent ( ) : AddressSpaceElement
Résultat	AddressSpaceElement

QueryAddressSpaceElementChildren() public abstract méthode

Returns the collection of children of the address space element to the element ID provided. This interface needs to be implemented in the string based object space case

public abstract QueryAddressSpaceElementChildren ( string anElementID, ArrayList aChildrenList ) : int
