public class connect
extends X3DConcreteStatement

Functional summary: connect statements define event-routing connections between node fields defined inside a ProtoBody declaration back to corresponding ProtoInterface fields. This concrete class represents an X3D connect statement.

connect statement tooltip: connect statements define event-routing connections between node fields defined inside a ProtoBody declaration back to corresponding ProtoInterface fields. To define each Prototype connection between a ProtoInterface field and a ProtoBody node field, add one or more connect statements within each IS statement.

• Warning: IS/connect elements are only allowed within ProtoDeclare body definitions.
• Warning: nodeField and protoField types must match.
• Hint: any matching field type can be connected, including SFNode or MFNode.
• Hint: if provided, value of the outer ProtoInstance fieldValue overrides default value of inner IS/connect nodeField (defined within the original prototype declaration) when first creating a new ProtoInstance node.
• Hint: see the IS and ProtoBody statements.
• Hint: X3D Architecture 4.4.4 Prototype semantics, https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/concepts.html#PROTOdefinitionsemantics Examples: X3D Example Archives, X3D for Web Authors, Chapter 14 Prototypes https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter14Prototypes
