public class IS
extends X3DConcreteStatement

Functional summary: the IS statement connects node fields defined inside a ProtoBody declaration back to corresponding ProtoInterface fields. IS/connect statements can be added if the parent node is within a ProtoBody and connect statements define correspondences between prototype fields and built-in node fields. This concrete class represents an X3D IS statement.

IS statement tooltip: The IS statement connects 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 statements are only allowed within a ProtoBody definition scope, which follows ProtoInterface field declarations, and thus are only found within a ProtoDeclare statement.
• Hint: if present, an IS statement is the first child within any other node.
• Hint: an IS statement precedes any sibling Metadata* node, which in turn precedes any other sibling nodes.
• Hint: see the connect 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
