copyout() [2/2]

template<class T>

Array< T > aff::ConstArray< T >::copyout

create an identical copy (deep copy) of this array

create a value (deep) copy

This is mainly used to create a copy of a truely identical array (i.e. array with same element type or at least const version of same element type). Use this function in conjunction with the assignment operator. E.g.:

aff::Array<int> A(3,4);
A=5.;
aff::Array<int> B, C;
B=A.copyout();
C=A;

Here arrays A and B have exactly the same contents but use different memory. While changes to elements of C will also affect elements of A, this not the case for changes applied to B.

Examples:

tests/arraytest.cc, and tests/helpertest.cc.
