Class Contour2DObject

java.lang.Object
All Implemented Interfaces:
X3DNode, Contour2D

public class Contour2DObject
extends X3DConcreteNode
implements Contour2D
Contour2D groups a set of curve segments into a composite contour.

X3D node tooltip: [X3DNode] Contour2D groups a set of curve segments into a composite contour. The children segments form a closed loop, with first point of first child repeated as last point of last child, and last point of each segment repeated as the first point of the next consecutive segment. The children segments are type NurbsCurve2D or ContourPolyline2D, enumerated in the consecutive order of contour topology.
  • Warning: Contour2D is not a renderable geometry node.
  • Hint: Contour2D is used as the trimmingContour field of the NurbsTrimmedSurface node.

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.

      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)
      Returns:
      object reference to found element, null otherwise

    • 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 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
      See Also:
      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
      See Also:
      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)
