Interface MetadataSet

All Superinterfaces:
X3DMetadataObject, X3DNode
All Known Implementing Classes:

public interface MetadataSet extends X3DNode, X3DMetadataObject
The metadata provided by this node is contained in the metadata nodes of the value field.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. MetadataSet node tooltip: [X3DNode,X3DMetadataObject] MetadataSet contains a list of Metadata* nodes that each have containerField="value" and together provide information about the parent node of the MetadataSet. Further information about this specific MetadataSet node may be provided by a single child Metadata* node with containerField="metadata".
  • Hint: typically use containerField="value" if the parent node is MetadataSet.
  • Warning: default containerField="metadata" in X3D 3 changed to default containerField="value" in X3D 4.0, allowing construction of much terser MetadataSet vocabulary structures.
  • Hint: explicitly defining containerField for Metadata nodes is always allowed and also unambiguous across each version of X3D.
  • Hint: each of the Metadata nodes are allowed as top-level root nodes in a scene, if doing that be sure to explicitly define containerField='metadata'.
  • Warning: Metadata nodes can only contain other Metadata nodes.
  • 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: MetadataSet can contain other MetadataSet nodes.
  • Hint: comments are not readable when a model file is loaded for viewing, but WorldInfo and Metadata* nodes are persistent and inspectable at run time.
  • Hint: X3D for Web Authors, Chapter 15, Metadata Information

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
