groupFilter component: filter node group. Groups multiple Filter nodes into a group, and if all nodes are True, sends the data to the True chain, otherwise sends it to the False chain. If allMatches=false, then as long as any node returns True, it sends it to the True chain

Configuration

Field	Type	Required	Description	Default value
allMatches	bool	No	Whether all nodes are required to match	false
nodeIds	string	Yes	List of node IDs in the group, multiple IDs separated by ,	-
timeout	int	No	Execution timeout, in seconds, default: 0 means no timeout	0

Relation Type

• True: Send the message to the True chain
• False: Send the message to the False chain
• Failure: nodeIds is empty or execution timed out, send to the Failure chain

allMatches=true All nodes must match to send to the True chain, if false, then as long as any node matches, it sends to the True chain

Execution result

This component will not change the content of msg, metadata and msgType.
