Detailed Description

data processing node

The structure forms a node element in a directed acyclic graph. It's connectors allow to communicate cababilities and semantics. This node type acts mostly on data processing.

It is possible to delegate parameter or context creation to other specialised filter types. The filter context can be stored in oyFilterNode_s::backend_data if the oyCMMapi7_s::context_type is filled with a understood format hint. The registration should provide keywords to select the processing function.

(in CM jargon - interpolator)

oyConnector_s** oyCMMapi7_s::plugs

We have to tell about valid input and output connectors, by passively providing enough informations.

Referenced by oyFilterNode_s::oyFilterNode_GetConnectorPos(), and oyFilterNode_s::oyFilterNode_ShowConnector().

uint32_t oyCMMapi7_s::plugs_last_add

additional allowed number for last input connector, e.g. typical 0

int32_t oyCMMapi7_s::version[3]

0: major - should be stable for the live time of a filter,
1: minor - mark new features,
2: patch version - correct errors

Reimplemented from oyCMMapiFilter_s.
