X3D node tooltip: (X3D version 3.2 or later) [X3DChaserNode] ScalarChaser generates a series of single floating-point values that progressively change from initial value to destination value.

• Hint: ROUTE value_changed output events to an interpolator node's set_fraction field, for example.

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,
                                                 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

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

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)
