### Short Description

The Subgraph component represents whole subgraph in parent graph.

Component | Same input metadata | Sorted inputs | Inputs | Outputs | Each to all outputs | Java | CTL | Auto-propagated metadata
--- | --- | --- | --- | --- | --- | --- | --- | ---
Subgraph | – |  | 0-n | 0–n |  | – | – | [1]
[1] The component Subgraph can propagate metadata through itself or auto-propagate metadata on it's ports. The metadata auto-propagation depends on metadata assigned on edges in the subgraph.

### Abstract

Component Subgraph serves for launching of subgraphs from graph. The subgraph functionality is user defined and depends on particular subgraph being used.

For details about subgraphs see Part VI, Subgraphs.

### Ports

Port type | Number | Required | Description | Metadata
--- | --- | --- | --- | ---
Input | 0-n | [1] | Input of Subgraph | Depends on Subgraph
Output | 0-n | [2] | Output of Subgraph | Depends on Subgraph
[1] All input ports defined by SubgraphInput component in corresponding subgraph are required. [2] All output ports defined by SubgraphOutput component in corresponding subgraph are required.

### Metadata

The component Subgraph can propagate metadata through itself or auto-propagate metadata on it's ports.

The metadata auto-propagation depends on metadata assigned on edges in the subgraph.
