Description

Methods

Public constructor Create(const AX3DName: string = ''; const ABaseUrl: String = ''); override;

This item has no description. Showing description inherited from TX3DNode.Create.

Constructor. Initializes various properties:

  • Name, BaseUrl are initialized from given parameters.

  • The Fields, Events lists are filled in every descendant, to have all the fields/events defined by the specification.

  • DefaultContainerField, and other node-specific stuff, is filled in descendants. This is actually implemented in CreateNode, that is called at the end of this constructor.

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.
