Clone of a prototype.
Library: ilvproto
IlvProtoInstance is a subclass of IlvGroup that represents instances of IlvPrototype. An IlvProtoInstance points to its prototype, and can automatically save (to a file) only the accessor values that have been changed with respect to its prototype.
| IlvProtoInstance::IlvProtoInstance | ( | const IlvProtoInstance & | source | ) |
Copies an existing instance.
The new instance is added to the prototype instance list. There is no other public constructor for IlvProtoInstance. Instances must be created by calling the IlvPrototype::clone method.
| IlUInt IlvProtoInstance::getModifiedValues | ( | IlvValueArray & | diffs, |
| IlBoolean | any = IlFalse |
||
| ) | const |
Computes the values that have been modified for this instance with respect to its prototype.
The list of these values is added to the end of the diffs table (if this table already contains elements, they will not be overwritten).
This method is used when saving prototype instances. Storing the modified values between a prototype and a prototype instance allows you to edit the prototype, and then propagate the improvements to all the instances of the prototype. This propagation is done with the update method. This has some restrictions: if the prototype evolves drastically, the modified values may no longer be relevant.
| diffs | Array of values that differ between the prototype and its instance. |
| any | Set to IlTrue if the difference is to account for values of class IlvValueAnyType or other values whose type is unknown. |
| IlvPrototype* IlvProtoInstance::getPrototype | ( | ) | const |
Returns the prototype of the instance.
Updates the group (deep-inplace copy).
Uses compareValues to store the differing values between this and source, replaces all the nodes and behaviors of this by those of source, and then reassigns the previously stored differing values to this (by calling changeValues. This method is mainly used to update IlvProtoInstances when a prototype is modified.
| source | Group to update from. |
Reimplemented from IlvGroup.
