| void PLearn::ScaledGaussianKernel::makeDeepCopyFromShallowCopy | ( | CopiesMap & | copies | ) | [virtual] |
Does the necessary operations to transform a shallow copy (this) into a deep copy by deep-copying all the members that need to be.
This needs to be overridden by every class that adds "complex" data members to the class, such as Vec, Mat, PP<Something>, etc. Typical implementation:
void CLASS_OF_THIS::makeDeepCopyFromShallowCopy(CopiesMap& copies) { inherited::makeDeepCopyFromShallowCopy(copies); deepCopyField(complex_data_member1, copies); deepCopyField(complex_data_member2, copies); ... }
| copies | A map used by the deep-copy mechanism to keep track of already-copied objects. |
Reimplemented from PLearn::Kernel.
