ConnectionCompleteContext<T> class

Context provided when attempting to complete a connection.

This context is passed to validation callbacks when a user attempts to complete a connection by dropping on a target port. It provides complete information about both the source and target to enable comprehensive validation logic.

Usage Example

ConnectionValidationResult validateComplete<T>(
  ConnectionCompleteContext<T> context,
) {
  // Prevent self-connections
  if (context.isSelfConnection) {
    return ConnectionValidationResult.deny(
      reason: 'Cannot connect node to itself',
      showMessage: true,
    );
  }

  // Only allow output-to-input connections
  if (!context.isOutputToInput) {
    return ConnectionValidationResult.deny(
      reason: 'Must connect output to input',
      showMessage: true,
    );
  }

  return ConnectionValidationResult.allow();
}
