Graph
The
Graph represents the processing workflow for a capture session.
Fields of a Graph
Note: The terms "object," "array," "string," and "number," refer to JSON data types. The term "boolean" refers to the JSON values true and false. All other type names refer to data types specific to the CaptureCast platform.
nodes |
array of Nodes |
Yes |
Nodes of the graph. |
Fields of a Node
nodeID |
number |
Yes |
ID of node. |
workingDir |
string |
No |
Working directory of node. If not specified, it is automatically generated. |
connectedTo |
array of numbers |
Yes |
IDs of child nodes. This node will send data to these indicated nodes. |
config |
string |
Yes |
Configuration used to create a processor. This is usually a JSON string. |
