Detailed Description

A DataLink links too variables in memory.

Two addresses of the same type of data are linked by a DataLink. Once linked, the value of the first one (second one) is copied in the second one (first one) each time the CopyA1_to_A2 (CopyA2_to_A1) method is called.

Both values could be set to a default value by calling the Reset method. The default value are set in the constructor

Be careful, it is the charge of the user to be sure a DalaLink is correctly linked with two valid addresses.

UShort_t a1, a2; DataLinkImp<UShort_t> link; 

a1 = 1; a2 = 2; 
link(&a1,&a2); 
link.CopyA1_to_A2(); ==> a1 = a2 = 1

a2 = 2;
link.CopyA2_to_A1(); ==> a1 = a2 = 2

link.Reset(); ==> a1 = a2 = 0

With this, user's variables could be linked on the basis of a common name.

See for instance ANamedItem, NamedItem and GObject.
