ScXMLDataElt(3)

💖 ScXMLDataElt 💖

okay bestie, welcome to the ScXMLDataElt(3) page, straight outta the Coin manual ✨ this is the one about the <data> SCXML element and honestly? it's giving variable storage icon behavior 👑

🎀 NAME 🎀

ScXMLDataElt — the <data> SCXML element. periodt.

🌸 SYNOPSIS 🌸

#include <Inventor/scxml/ScXMLDataElt.h>

Inherits ScXMLElt.

⭐ Static Public Member Functions inherited from ScXMLObject

• static SoType getClassTypeId (void) — this static method returns the SoType object associated with objects of this class.
• static void initClass (void) — sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
• static void cleanClass (void) — does the opposite of initClass, deallocates any class specific resources and resets the class to an uninitialized state with respect to the Coin type system.

💜 Protected Attributes

• char * ID
• char * src
• char * expr
• ScXMLDataObj * value

👑 Detailed Description 👑

the <data> SCXML element. that's the whole vibe of this class, fr fr.

The <data> SCXML element is for storing variables. 🍓 They need to be contained within a <datamodel> element. <data> elements are only functional in state machines with a profile that has an implementation of the Data Module. The "minimum" profile does not, but the "x-coin" profile does. (so pick your profile wisely bestie, it's lowkey a whole thing 😭)

The following attributes are accepted:

• ID
• src — not supported 🙈
• expr

The ID attribute is required and specifies the variable name. The variable name must be unique for the whole SCXML state machine specification. (yes, the whole thing, don't be messy 💅)

The src attribute is not supported. like, at all. moving on.

The expr attribute specifies the value of the variable. The attribute is evaluated based on which profile the state machine is using.

The value of the <data> variable can be changed through the use of <assign> elements, and their values can be passed on to other systems through the use of the <send> element in the External Communications Module. 🔥

💀 Member Function Documentation 💀

🌸 SoType ScXMLDataElt::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

• See also — SoBase::getTypeId() const
• Implements — ScXMLElt.

🦋 SbBool ScXMLDataElt::handleXMLAttributes (void ) [virtual]

This method is called when the file reader has set all the XML attributes on the object, and wants the object to handle them and report if the values were OK or if a read error should be produced.

• Returns — TRUE if the attributes are OK, and FALSE on error.

This base class implementation does nothing and just returns TRUE. (iconic minimal effort behavior honestly ✨)

• Reimplemented from — ScXMLElt.

💖 void ScXMLDataElt::copyContents (const ScXMLElt * rhs) [virtual]

• Reimplemented from — ScXMLElt.

🎀 const ScXMLElt * ScXMLDataElt::search (const char * attrname, const char * attrvalue) const [virtual]

This method searches the SCXML structure for an element with the given attribute value for the given attribute.

Returns NULL if nothing was found. 😭

This function needs to be reimplemented to traverse child elements.

• Reimplemented from — ScXMLElt.

okay that's the whole page bestie, you ate that 💅✨ this was Version 4.0.10, dated Thu Jun 25 2026 00:00:00, and yes it's ScXMLDataElt(3) in the Coin manual, so go forth and store those variables responsibly, mwah 💖🦋🌸
