◆ ADTF_IID()

ADTF_IID ( IObject  ,
"object.ant.ucom.adtf.iid"   
)

Marks the IObject to be castable with the ucom_cast()

See also
ADTF_IID(_interface, _striid)

◆ Destroy()

virtual tVoid Destroy ( ) const
privatepure virtual

Destruct and deallocate instantiations of type IObject.

To safely deallocate arbitrary objects between binary boundaries, the usage of ordinary deallocation (e.g. delete or free) is strongly disadvised. Allocators and deallocator implementations might differ in different compiling modes which might result in undefined behavior if allocating an object in mode A (e.g. Release) and deallocating it in mode B (e.g. Debug). To ensure that an object is always allocated and deallocated on the same side of a DLL, method Destroy() can be used. The usual implementation of Destroy() just calls delete *this as allocating usually works using new. When calling IObject::Destroy() on an instantiated object, the vtable of pure abstract interface IObject points to the correct implementation of Destroy() ensuring correct destructor calling and deallocation.

Returns
Nothing

◆ GetInterface() [1/2]

virtual tResult GetInterface ( const tChar i_strIID,
tVoid *&  o_pInterface 
)
privatepure virtual

Query interfaces on an object.

The IObject::GetInterface method returns a pointer to a specified interface on an object to which a client currently holds an interface pointer. Due to the fact that this querying of interfaces is not at all type safe, the IObject::GetInterface methods reside inside the private section of the interface and can only be accessed by ucom_cast() function template.

Parameters
[in]i_strIIDIdentifier of the interface being requested.
[out]o_pInterfaceAddress of pointer variable that receives the interface pointer requested in idInterface. Upon successful return, *o_pInterface contains the requested interface pointer to the object. If the object does not expose the interface specified in i_strIID, i_pInterface is set to NULL.
Returns
Standard error.
Return values
ERR_NOERRORThe interface identified by i_strIID was implemented and exposed by the implementation of *this. o_pInterface points to the queried interface.
ERR_NO_INTERFACEThe requested interface is not exposed. o_pInterface==NULL

[out]o_pInterfaceAddress of pointer variable that receives the interface pointer requested in idInterface. Upon successful return, *o_pInterface contains the requested interface pointer to the object. If the object does not expose the interface specified in i_strIID, i_pInterface is set to NULL.
Returns
Standard error.
Return values
ERR_NOERRORThe interface identified by i_strIID was implemented and exposed by the implementation of *this. o_pInterface points to the queried interface.
ERR_NO_INTERFACEThe requested interface is not exposed. o_pInterface==NULL
