Detailed Description

An abstract property is a serializable (name,value) pair, for which we do not know the type of the value.

Values may be simple types like int or string, or may be serializable objects derived from the OpenSim Object class.

AbstractProperty is an abstract base class that provides the functionality common to all properties that does not involve knowledge of the value type. Property<T> derives from AbstractProperty to represent properties where the type is known.

◆ empty()

bool OpenSim::AbstractProperty::empty ( ) const
inline

Return true if this property's value list is currently empty.

◆ equals()

bool OpenSim::AbstractProperty::equals ( const AbstractProperty other) const
inline

Compare this property with another one; this is primarily used for testing.

The properties must be of the identical concrete type, and their names and other base class attributes must be identical (including the comment). If they both have the "use default" flag set then we consider the values identical without looking. Otherwise, we delegate to the concrete property to determine if the values are equal; the meaning is determined by the concrete property depending on its type. Floating point values should be compared to a tolerance, and should be considered equal if both are the same infinity or both are NaN (the latter in contrast to normal IEEE floating point behavior, where NaN!=NaN).

◆ getValue()

template<class T >
const T & OpenSim::AbstractProperty::getValue ( int  index = -1) const
inline

Return one of the values in this property as type T; this works only if the underlying concrete property stores type T and if the indexed element is present, otherwise throws an exception.

References OpenSim::Property_Deprecated::getValue(), OpenSim::Property_Deprecated::getValueArray(), and OpenSim::Property_Deprecated::isArrayProperty().

◆ getValueAsObject()

virtual const Object& OpenSim::AbstractProperty::getValueAsObject ( int  index = -1) const
pure virtual

For an object property, the values can be obtained as references to the abstract base class Object from which all the objects derive.

If the property can hold a list of values you must provide an index to select the value, otherwise it is optional but if supplied must be 0. This will throw an exception if this is not an object property, that is, if it is a simple property, because its values can't be represented as an Object in that case.

Parameters
[in]indexIf supplied must be 0 <= index < getNumValues().
Returns
const reference to the value as an Object

virtual bool OpenSim::AbstractProperty::isAcceptableObjectTag ( const std::string &  objectTypeTag) const
protectedpure virtual

Return true if the given string is the XML tag name for one of the Object-derived types that is allowed by this property.

If so, we expect that an element with that tag could be deserialized into a value element of this property. This always returns false for a simple property.

◆ isEqualTo()

virtual bool OpenSim::AbstractProperty::isEqualTo ( const AbstractProperty other) const
protectedpure virtual

The base class equals() method will have already done a lot of checking prior to calling this method, including verifying that both values are non-default and that the value lists are the same size; the concrete property need only compare the values.

Implemented in OpenSim::Property_Deprecated.

Referenced by OpenSim::Property< T >::getTypeName().

◆ isListProperty()

bool OpenSim::AbstractProperty::isListProperty ( ) const
inline

This is a "list" property if its value list can contain more than one value.

This is the kind of property created by the Object::addListProperty<T> method, for any type T.

Referenced by OpenSim::Property< T >::setValue().

◆ isObjectProperty()

virtual bool OpenSim::AbstractProperty::isObjectProperty ( ) const
pure virtual

Return true if this is an "object property", meaning that its values are all concrete objects of types that ultimately derive from the OpenSim serializable base class Object.

If this returns true then it is safe to call getValueAsObject(). Otherwise this property contains only simple types like "int" or "std::string", and you'll need to know the actual type in order to access the values.

◆ isOneObjectProperty()

bool OpenSim::AbstractProperty::isOneObjectProperty ( ) const
inline

This is a "one-object" property if it is a "one-value" property and it contains an Object-derived value.

This is the kind of property created by the Object::addProperty<T> method when T is a type derived from OpenSim's Object serializable base class. One-object properties have a special, compact representation in XML.

◆ isOneValueProperty()

bool OpenSim::AbstractProperty::isOneValueProperty ( ) const
inline

This is a "one-value" property if its value list must always contain exactly one value.

This is the kind of property created by the Object::addProperty<T> method, for any type T.

Referenced by OpenSim::Property< T >::getTypeName().

◆ isOptionalProperty()

bool OpenSim::AbstractProperty::isOptionalProperty ( ) const
inline

This is an "optional" property if its value list can contain at most one value.

This is the kind of property created by the Object::addOptionalProperty<T> method, for any type T.

◆ isSamePropertyClass()

bool OpenSim::AbstractProperty::isSamePropertyClass ( const AbstractProperty other) const
inline

Return true if the other property is an object of exactly the same concrete class as this one.

◆ isUnnamedProperty()

virtual bool OpenSim::AbstractProperty::isUnnamedProperty ( ) const
pure virtual

An unnamed property is a one-object property whose name was given as null or as the contained object's type tag.

In that case getName() will return the object type tag, and the XML representation will just be the object, with name attribute ignored if there is one.

◆ readFromXMLElement()

virtual void OpenSim::AbstractProperty::readFromXMLElement ( SimTK::Xml::Element &  propertyElement,
int  versionNumber 
)
protectedpure virtual

Read in a new value for this property from the XML element propertyElement.

The element is expected to have the form

<propertyName> value(s) </propertyName>

where the values may be simple (like int or double) or may be objects contained in child elements for which the object type name serves as the element tag. Note that although the XML file may contain an abbreviated representation for one-object properties, it will have been canonicalized into the above form for the purpose of reading, so concrete properties may assume the above form always.

The format for the property value (and any of its contained objects) is assumed to be the one that was in use when the given ".osim" file version number was current; if necessary the in-memory version will be updated to the now-current format.

If this is an object property, the contained objects will be asked recursively to read themselves in from the same document. However, any object that has the "file" attribute will read in its contents from that file rather than from the supplied XML document, and the version number will be taken from that file rather than the argument supplied here.

Implemented in OpenSim::Property_Deprecated.

◆ readFromXMLParentElement()

void OpenSim::AbstractProperty::readFromXMLParentElement ( SimTK::Xml::Element &  parent,
int  versionNumber 
)

Given an XML parent element expected to contain a value for this property as an immediate child element, find that property element and set the property value from it.

If no such property element can be found, the "use default value" attribute of this property will be set on return; that is not an error. However, if the property element is found but is malformed or unsuitable in some way, an exception will be thrown with a message explaining what is wrong.

inline

Require that the number of values n in the value list of this property be exactly n=aNum values.

◆ setAllPropertiesUseDefault()

void OpenSim::AbstractProperty::setAllPropertiesUseDefault ( bool  shouldUseDefault)

This method sets the "use default" flag for this property and the properties of any objects it contains to the given value.

◆ setComment()

void OpenSim::AbstractProperty::setComment ( const std::string &  aComment)
inline

Set a user-friendly comment to be associated with property.

This will be displayed in XML and in "help" output for OpenSim Objects.

◆ toString()

virtual std::string OpenSim::AbstractProperty::toString ( ) const
pure virtual

For relatively simple types, return the current value of this property in a string suitable for displaying to a user in the GUI (i.e., this number may be rounded and not an exact representation of the actual value being used).

Objects just return something like "(Object)". For Propertys, This function calls toStringForDisplay() with precision = 6.

◆ toStringForDisplay()

virtual std::string OpenSim::AbstractProperty::toStringForDisplay ( const int  precision) const
inlinevirtual

For relatively simple types, return the current value of this property in a string suitable for displaying to a user in the GUI (i.e., this number may be rounded and not an exact representation of the actual value being used).

Objects just return something like "(Object)". This differs from toString() as it has an argument, precision, for controlling the number of digits printed to string for floats. If this function is not overridden in a derived class, this function uses toString() and the precision argument is ignored. For Propertys, in general, this means that floats will be represented with the number of significant digits denoted by the precision argument, and the default formatting of stringstream determines whether or not exponential notation is used.

◆ updValue()

template<class T >
T & OpenSim::AbstractProperty::updValue ( int  index = -1)
inline

Return a writable reference to one of the values in this property as type T; this works only if the underlying concrete property is actually of type T and the indexed element is present.

Otherwise it throws an exception.

◆ updValueAsObject()

virtual Object& OpenSim::AbstractProperty::updValueAsObject ( int  index = -1)
pure virtual

Get writable access to an existing object value.

Note that you can't use this to install a different concrete object; see setValueAsObject() if you want to do that.

Parameters
[in]indexIf supplied must be 0 <= index < getNumValues().
Returns
writable reference to the value as an Object

◆ writeToXMLElement()

virtual void OpenSim::AbstractProperty::writeToXMLElement ( SimTK::Xml::Element &  propertyElement) const
protectedpure virtual

Output a serialized representation of this property by writing its value to the given XML property element.

If the "use default value" attribute is set for this property (meaning we don't have a meaningful value for it) then you should not call this method unless you are trying to serialize the defaults. Note that this method unconditionally serializes the property; it does not check to see whether it should.

This method is not called for the special case of a one-object property, in which case only the object is written to the XML file (without the property element). In all other cases (simple property or property containing an array of objects), the format is

<propertyName> value(s) </propertyName>

and that is the only format produced here since the empty-valued property element is supplied (with the property name as its tag).

Implemented in OpenSim::Property_Deprecated.

◆ writeToXMLParentElement()

void OpenSim::AbstractProperty::writeToXMLParentElement ( SimTK::Xml::Element &  parent) const
