bool isValidObject (const Object *obj) const override
 
std::string getTypeName () const override
 This returns a string representation of this property's value type which will be the same as T::getClassName() for Object-derived types T, and some reasonably nice name for simple types, including at least "bool", "int", "double", "string", "Vec3", "Vector", and "Transform". More...

Member Function Documentation

◆ assign()

void OpenSim::PropertyObj::assign ( const AbstractProperty that)
overridevirtual

Assign (copy) property that to this object.

Implements OpenSim::AbstractProperty.

◆ clone()

PropertyObj* OpenSim::PropertyObj::clone ( ) const
overridevirtual

Return a new instance of this concrete property object, containing new copies of this property's values.

The new property object is allocated on the heap and it is up to the caller to delete it when done.

Implements OpenSim::Property_Deprecated.

◆ getTypeName()

std::string OpenSim::PropertyObj::getTypeName ( ) const
inlineoverridevirtual

This returns a string representation of this property's value type which will be the same as T::getClassName() for Object-derived types T, and some reasonably nice name for simple types, including at least "bool", "int", "double", "string", "Vec3", "Vector", and "Transform".

Implements OpenSim::Property_Deprecated.

◆ getValueAsObject()

const Object& OpenSim::PropertyObj::getValueAsObject ( int  index = -1) const
inlineoverridevirtual

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
See also
updValueAsObject(), getValue<T>()

Reimplemented from OpenSim::Property_Deprecated.

◆ getValueObj() [1/2]

Object& OpenSim::PropertyObj::getValueObj ( )
overridevirtual

Reimplemented from OpenSim::Property_Deprecated.

◆ getValueObj() [2/2]

const Object& OpenSim::PropertyObj::getValueObj ( ) const
overridevirtual

Reimplemented from OpenSim::Property_Deprecated.

◆ isAcceptableObjectTag()

bool OpenSim::PropertyObj::isAcceptableObjectTag ( const std::string &  objectTypeTag) const
inlineoverridevirtual

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.

Reimplemented from OpenSim::Property_Deprecated.

◆ isObjectProperty()

bool OpenSim::PropertyObj::isObjectProperty ( ) const
inlineoverridevirtual

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.

Reimplemented from OpenSim::Property_Deprecated.

◆ isValidObject()

bool OpenSim::PropertyObj::isValidObject ( const Object obj) const
inlineoverridevirtual

Reimplemented from OpenSim::Property_Deprecated.

◆ operator=()

PropertyObj& OpenSim::PropertyObj::operator= ( const PropertyObj aProperty)

◆ setValueAsObject()

void OpenSim::PropertyObj::setValueAsObject ( const Object obj,
int  index = -1 
)
inlineoverridevirtual

Set the indicated value element to a new copy of the supplied object.

If you already have a heap-allocated object you're willing to give up and want to avoid the extra copy, use adoptValueObject().

Reimplemented from OpenSim::Property_Deprecated.

References OpenSim::Object::clone().

◆ toString()

std::string OpenSim::PropertyObj::toString ( ) const
overridevirtual

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.

Implements OpenSim::Property_Deprecated.

◆ updValueAsObject()

Object& OpenSim::PropertyObj::updValueAsObject ( int  index = -1)
inlineoverridevirtual

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
See also
getValueAsObject(), updValue<T>()

Reimplemented from OpenSim::Property_Deprecated.
