Class MetadataSet

java.lang.Object
All Implemented Interfaces:
MetadataSet, X3DMetadataObject, X3DNode

public class MetadataSet
extends X3DConcreteNode
implements MetadataSet
The metadata provided by this node is contained in the metadata nodes of the value field.

X3D 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: use containerField="value" if the parent node is MetadataSet.
  • Hint: if a metadata node is needed as a top-level root node for the scene, first insert a parent WorldInfo (or WorldInfo/MetadataSet) to contain it.
  • 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 http://x3dgraphics.com/examples/X3dForWebAuthors/Chapter15-Metadata/Chapter15-MetadataInformation.html

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

    • findElementByNameValue

      public X3DConcreteElement findElementByNameValue​(java.lang.String nameValue)
      Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same name, this method does not handle that case.
      Specified by:
      findElementByNameValue in class X3DConcreteElement
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      object reference to found element, null otherwise
      See Also:
      findNodeByDEF(String), X3DConcreteElement.hasAncestorScene(), X3DConcreteElement.findAncestorX3D()
    • findElementByNameValue

      public X3DConcreteElement findElementByNameValue​(java.lang.String nameValue, java.lang.String elementName)
      Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same name, this method does not handle that case.
      Specified by:
      findElementByNameValue in class X3DConcreteElement
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)
      Returns:
      object reference to found element, null otherwise
      See Also:
      findNodeByDEF(String), X3DConcreteElement.hasAncestorScene(), X3DConcreteElement.findAncestorX3D()
    • hasElementByNameValue

      public boolean hasElementByNameValue​(java.lang.String nameValue, java.lang.String elementName)
      Recursive method to determine whether node or statement with given name attribute is found, meaning both objects are attached to same scene graph.
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)
      Returns:
      whether node is found
      See Also:
      findElementByNameValue(String, String)
    • findNodeByDEF

      public X3DConcreteNode findNodeByDEF​(java.lang.String DEFvalue)
      Recursive method to provide object reference to node by DEF, if found as this node or in a contained node.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same DEF, this method does not handle that case.
      Specified by:
      findNodeByDEF in class X3DConcreteElement
      Parameters:
      DEFvalue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      object reference to found node, null otherwise

    • hasNodeByDEF

      public boolean hasNodeByDEF​(java.lang.String DEFvalue)

      Parameters:
      DEFvalue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      whether node is found
