Mutable Grid Function Concept

Description

The Mutable Grid Function concept refines the Grid Function concept. It allows to change function values, that is, to store values on elements.

Refinement of

Grid Function

Notation

F is a type which is a model of Mutable Grid Function
f is an object of type F
i is an object of F::iterator
t is an object of F::value_type

Associated types

Name	Expression	Description
mutable value iterator	`F::iterator`	iterator over the values of `f` model of STL Forward Iterator

Valid Expressions

Name	Expression	Type requirements	return type
start of value sequence	`f.begin();`		`F::iterator`
end of value sequence	`f.end();`		`F::iterator`
write access	`f[e];`		`F::value_type&`

Expression semantics

Name	Expression	Precondition	Semantics	Postcondition
start of value sequence	`i = f.begin();`	`f` is bound to a grid	return iterator to start of value sequence	`distance(i,f.end()) == f.size()`
end of value sequence	`i = f.end();`	`f` is bound to a grid	return iterator to past-the-end of value sequence	`i` is past-the-end, `i == f.end()`
write access	`f[e] = t;`	`f` is bound to a grid `e.TheGrid() == f.TheGrid()`	assign the value `t` to `f(e)`	`f(e)` is equal to `t`
