HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
Return valueFurther information
The function F_VN_CopyContainerElementsConditional_ITcVnForwardIterator filters elements of multi-dimensional containers. The filter condition is to be specified by a function block with the interface ITcVnCustomElementCondition_ITcVnForwardIterator.
Unlike F_VN_CopyContainerElementsConditional_ITcVnContainer, sub-containers are not transferred to the conditional method Condition, but iterators, which each point to the first element of the sub-container.
Parameter
Input container
The input container ipSrcContainer must be a multi-dimensional container; i.e. the container must contain sub-containers as elements. Thus all containers of the type ContainerType_Vector_Vector_<…> can be used.
Result container
The result container ipDestContainer contains all sub-containers that satisfy the condition in ipConditionFB.
Filter condition
The filter condition must be defined as the method Condition of a function block. So that this function block can be transferred to the function as the parameter ipConditionFB, it must implement the interface ITcVnCustomElementCondition_ITcVnForwardIterator.
