public class headObject
extends X3DConcreteStatement
Functional summary: each X3D scene includes a head statement that can contain component, unit and meta statements. This concrete class represents an X3D head statement.

X3D statement tooltip: [X3D statement] head can contain component, unit, and author-defined meta (metadata) elements.
  • Hint: design for this element is patterned after the <head> tag in HTML: https://www.w3.org/TR/html5/document-metadata.html#the-head-element
  • Warning: head is optional first child of X3D statement, and must precede the Scene statement.
  • Warning: in order to pass XML validation, these contained optional statements must appear in order: first component statements, then unit statements, then meta statements.

      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 findAncestorSceneObject() to check entire scene graph, or findAncestorX3DObject() 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

      findNodeByDEF(String), X3DConcreteElement.hasAncestorSceneObject(), X3DConcreteElement.findAncestorX3DObject()

    • 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 findAncestorSceneObject() to check entire scene graph, or findAncestorX3DObject() 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
      See Also:
      findElementByNameValue(String), X3DConcreteElement.hasAncestorSceneObject(), X3DConcreteElement.findAncestorX3DObject()

    • hasNodeByDEF

      public boolean hasNodeByDEF​(java.lang.String DEFvalue)
      Recursive method to determine whether node with DEFvalue is found, meaning both objects are attached to same scene graph.
      Parameters:
      DEFvalue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      whether node is found

      findNodeByDEF(String)

    • validate

      public java.lang.String validate()
      Recursive method to validate this element plus all contained nodes and statements, using both datatype-specification value checks and regular expression (regex) checking of corresponding string values.
      Specified by:
      validate in class X3DConcreteElement
      Returns:
      validation results (if any)
