Detailed Description
template<typename T>
class fv::PointerValue< T >
A Value of a pointer.
The pointer is constant, however the data the pointer points to is variable.
Member Function Documentation
§ update_value()
|
inlineprotectedvirtual |
Updates the internal value.
This function should be overridden by any child class to do the actual work of updating value based on whatever rules the class chooses. Normally, this consists of geting the values from some associated Value objects, doing some calculation on them, and storing the result in value.
Implements fv::DerivedValue< T *>.
§ verify_integrity()
|
inlineprivatevirtual |
This function serves to check that this Value has been created with real, i.e.
non null, arguments. This is to avoid segfaulting when a dynamic_cast fails. If no checks need to be made, simple override this method with a no-op. If checks fail, the function should utilize the CRITICAL macro with a meaningfull error message stating what failed and especially the name of the current value.
Implements fv::GenValue.
