#include <VectorIterator.h>
Inheritance diagram for VectorIterator< Row >:
If we have a vector with a row type Row, e.g. vector<FooBar>, then a VectorFloatFun allows to iterate over all elements of the vector and return the value of one data member.
Let's assume we have a class FooBar defined like this:
class FooBar { public: float foo; int bar; float foobar() const { return foo*bar; } };
class DataLoop: public EventLoop { public: DataLoop(); ~DataLoop(); void loop(); private: vector<FooBar> foobarvector; };
void DataLoop::loop() { // fill foobarvector here foobarvector[xxx] = yyy; // Now fill the self-filling histos: EventLoop::loop(); }
void DataLoop::DataLoop() { VectorIterator<FooBar>& foobar_it = *new VectorIterator<FooBar> (foobarvector); FloatFun& foo_fun = foobar_it.Float (&FooBar::foo); FloatFun& bar_fun = foobar_it.Float (&FooBar::bar); FloatFun& foobar_fun = foobar_it.Float (&FooBar::foobar); }
The notation &FooBar::foo is probably unfamiliar. Such a thing is called a member pointer. Essentially it is a kind of offset that describes where within an object a data member is stored. For more information, see any good C++ text book.
