MSdpAttributeValueVisitor Class Reference

class MSdpAttributeValueVisitor

Abstract interface that can be implemented to receive an enumeration of the values in an attribute list.

The class member functions are called by an CSdpAttrValue (or one of its sub-classes) object when CSdpAttrValue::AcceptVisitorL() is called.

Note that:

When AcceptVisitorL() is called on attributes that are not lists (not DEA or DES), only VisitAttributeValueL() is called, passing the attribute value object itself (i.e. *this), and the value attribute type.

When AcceptVisitorL() is called on attributes that are lists (DEA or DES), VisitAttributeValueL() is called for each member of the list

This implements the standard Visitor pattern.

CSdpAttrValue::AcceptVisitorL()

Member Functions Documentation

EndListL()

voidEndListL()[pure virtual]

Called to indicate the end of a list of attribute values.

MSAVV_ExtensionInterfaceL(TUid, void *&)

IMPORT_C voidMSAVV_ExtensionInterfaceL(TUidaInterface,
void *&aObject
)[virtual]

Returns a null aObject if the extension is not implemented, or a pointer to another interface if it is.

Parameters

TUid aInterfaceUID of the interface to return
void *& aObjectthe container for another interface as specified by aInterface

StartListL(CSdpAttrValueList &)

voidStartListL(CSdpAttrValueList &aList)[pure virtual]

Called to indicate the start of a list of attribute values.

This call is followed by a call to VisitAttributeValueL() for each attribute value in the list, and concluded by a call to EndList().

Parameters

CSdpAttrValueList & aListAttribute value list

VisitAttributeValueL(CSdpAttrValue &, TSdpElementType)

voidVisitAttributeValueL(CSdpAttrValue &aValue,
TSdpElementTypeaType
)[pure virtual]

Called to pass an attribute value.

Parameters

CSdpAttrValue & aValueAttribute value
TSdpElementType aTypeValue type
