Class ScriptObject

  • All Implemented Interfaces:
    X3DChildNode, X3DNode, X3DUrlObject, Script, X3DScriptNode

    public class ScriptObject
    extends X3DConcreteNode
    implements Script
    X3D node tooltip: [X3DScriptNode] Script contains author-programmed event behaviors for a scene. Define the script input-output event interface by including <field/> elements. Scripting code is embedded in a child CDATA node or (deprecated) in the url field. Optionally supported programming languages are ECMAScript (JavaScript) and Java (via url to a myNode.class file).
    • Hint: insert a CDATA block to contain source code embedded within an X3D scene.
    • Hint: a contained CDATA block for source code protects whitespace, line breaks, and literal characters (such as & for ampersand character, < for less-than-sign character, and > for greater-than-sign character) from unintended escape-character modifications by XML parsers.
    • Warning: strict order is required for contained constructs: first field declarations (if any), then IS/connect statements (if any), and finally CDATA source-code block.
    • Hint: X3D Scene Authoring Hints, Scripts http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Scripts
    • Hint: apply containerField='watchList' when parent node is LoadSensor.

    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.

        • Hint: browsers are not required to support any particular scripting language, but ECMAScript (JavaScript) is widely supported.
        • Hint: equivalent script code written in multiple programming languages can be provided for portability, the first runnable version is chosen at run time.
        • Hint: X3D Scene Authoring Hints, Scripts http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Scripts
        • Warning: source code can be placed in url attribute but may be unparsable due to escaping of special characters and elimination of line breaks (causing comments to nullify follow-on code). Use contained CDATA section instead for embedding source code.
        • Hint: if both url field and CDATA section are provided simultaneously, the url field is processed first. This approach allows utilization of update modifications or live queries in external scripts, while still providing reliable script source as a fallback alternative within the model itself.
        • Hint: X3D XML Encoding, 4.3.13 Encapsulating Script node code http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#EncapsulatingScriptNodeCode
        • Hint: MFString arrays can have multiple values, so separate each individual string by quote marks "http://www.web3d.org" "http://www.web3d.org/about" "etc."
        • Hint: alternative XML encoding for quotation mark " is &quot; (which is an example of a character entity).
        • Warning: strictly match directory and filename capitalization for http links! This is important for portability. Some operating systems are forgiving of capitalization mismatches, but http/https url addresses and paths in Unix-based operating systems are all case sensitive and intolerant of uppercase/lowercase mismatches.
        • Hint: can replace embedded blank(s) in url queries with %20 for each blank character.

        public final ScriptObject setUSE​(java.lang.String newValue)
        Accessor method to assign String value to inputOutput SFString field named USE.

        Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
        • Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
        • Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
        • Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.


        Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

        Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

        Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
        Specified by:
        setUSE in class X3DConcreteNode
        Parameters:
        newValue - is new value for the USE field.
        Returns:
        ScriptObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
      • setUSE

        public ScriptObject setUSE​(SFStringObject newValue)
        Assign typed object value to SFString USE field, similar to setUSE(String).
        Parameters:
        newValue - is new value for the USE field.
        Returns:
        ScriptObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
      • getCssClass

        public java.lang.String getCssClass()

        • Hint: W3C Cascading Style Sheets https://www.w3.org/Style/CSS
        Overrides:
        getCssClass in class X3DConcreteNode
