Detailed Description

Provides introspection into the object providing openDAQ interface implementations.

Public Member Functions
virtual ErrCode INTERFACE_FUNC	getInterfaceIds (SizeT *idCount, IntfID **ids)=0
	Retrieves the Ids of interfaces this object implements. To find out the number of interfaces implemented and the needed size of the ids you can first call the function with the ids as nullptr which will then only return the size over the idCount parameter. More...
virtual ErrCode INTERFACE_FUNC	getRuntimeClassName (IString **implementationName)=0
	Gets the fully qualified name of the openDAQ object providing the implementation. More...

virtual ErrCode INTERFACE_FUNC	borrowInterface (const IntfID &intfID, void **obj) const =0
	Returns another interface which is supported by the object without incrementing the reference count. More...

	Disposes all references held by the object. More...
virtual ErrCode INTERFACE_FUNC	getHashCode (SizeT *hashCode)=0
	Returns hash code of the object. More...

	Returns a string representation of the object. More...

getInterfaceIds()

virtual ErrCode INTERFACE_FUNC getInterfaceIds ( SizeT *  idCount, IntfID **  ids  )

pure virtual

Retrieves the Ids of interfaces this object implements. To find out the number of interfaces implemented and the needed size of the ids you can first call the function with the ids as nullptr which will then only return the size over the idCount parameter.

Parameters

[out]	idCount	The number of interfaces implemented.
[out]	ids	The interface ids represented as an IntfID struct, if nullptr it is not populated.

getRuntimeClassName()

virtual ErrCode INTERFACE_FUNC getRuntimeClassName ( IString **  implementationName )

pure virtual

Gets the fully qualified name of the openDAQ object providing the implementation.

Parameters

implementationName

The actual implementation class name.
