| Return an array of pointers to the default instances of all registered (concrete) Object types that derive from a given Object-derived type that does not have to be concrete. More... | |
| static bool | PrintPropertyInfo (std::ostream &os, const std::string &classNameDotPropertyName, bool printFlagInfo=true) |
| Dump formatted property information to a given output stream, useful for creating a "help" facility for registered objects. More... | |
| static bool | PrintPropertyInfo (std::ostream &os, const std::string &className, const std::string &propertyName, bool printFlagInfo=true) |
| Same as the other signature but the class name and property name are provided as two separate strings. More... | |
| static Object * | makeObjectFromFile (const std::string &fileName) |
| Create an OpenSim object whose type is based on the tag at the root node of the XML file passed in. More... | |
| static const std::string & | getClassName () |
| Return the name of this class as a string; i.e., "Object". More... | |
| static void | setSerializeAllDefaults (bool shouldSerializeDefaults) |
| Static function to control whether all registered objects and their properties are written to the defaults section of output files rather than only those values for which the default was explicitly overwritten when read in from an input file or set programmatically. More... | |
| static bool | getSerializeAllDefaults () |
| Report the value of the "serialize all defaults" flag. More... | |
| static bool | isKindOf (const char *type) |
| Returns true if the passed-in string is "Object"; each Object-derived class defines a method of this name for its own class name. More... | |

| Set the amount of logging output. More... | |
| static int | getDebugLevel () |
| Get the current setting of debug level. More... | |
| static Object * | SafeCopy (const Object *aObject) |
| Use the clone() method to duplicate the given object unless the pointer is null in which case null is returned. More... | |
| static void | RegisterType (const Object &defaultObject) |
| OBSOLETE alternate name for registerType(). More... | |
| static void | RenameType (const std::string &oldName, const std::string &newName) |

A class implementing a Weld joint.
The underlying implementation in Simbody is a SimTK::MobilizedBody::Weld. There is no relative motion of bodies joined by a weld. Weld joints are often used to create composite bodies from smaller simpler bodies. You can also get the reaction force at the weld in the usual manner.

Create a new heap-allocated copy of the concrete object to which this Object refers.
It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.
Implements OpenSim::Joint.

Add appropriate Simbody elements (if needed) to the System corresponding to this component and specify needed state resources.
extendAddToSystem() is called when the Simbody System is being created to represent a completed system (model) for computation. That is, connect() will already have been invoked on all components before any addToSystem() call is made. Helper methods for adding modeling options, state variables and their derivatives, discrete variables, and cache entries are available and can be called within extendAddToSystem() only.
Note that this method is const; you may not modify your model component or the containing model during this call. Any modifications you need should instead be performed in finalizeFromProperties() or at the latest connect(), which are non-const. The only exception is that you may need to record access information for resources you create in the system, such as an index number. For most Components, OpenSim base classes either provide convenience methods or handle indices automatically. Otherwise, you must declare indices as mutable data members so that you can set them here.
If you override this method, be sure to invoke the base class method at the beginning, using code like this:
This method assumes that this Component's addToSystem will be invoked before its subcomponents. If you need your subcomponents to be added to the system, first (e.g. require of a Force to be anchored to a SimTK::MobilizedBody specified by subcomponents) then you must implement: extendAddToSystemAfterSubcomponents(). It is possible to implement both method to add system elements before and then after your subcomponents have added themselves. Caution is required that Simbody elements are not added twice especially when order is unimportant.

This returns "WeldJoint".
See getConcreteClassName() if you want the class name of the underlying concrete object instead.

inlineoverridevirtual |
Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.
This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.
Implements OpenSim::Joint.

For use in MATLAB and Python to access the concrete class.
Example: cObj = WeldJoint.safeDownCast(obj). This is equivalent to dynamic_cast<WeldJoint*>(obj) in C++.
