|
|
// CLASS DESCRIPTION (MDGModifier)
|
|
//
|
|
// An MDGModifier is used to change the structure of the dependency graph. This
|
|
// includes adding nodes, making new connections, and removing existing
|
|
// connections. An MDGModifier keeps track of all operations that it is
|
|
// used for, so that they can be undone or redone. Calling undo causes an
|
|
// MDGModifier to undo all of the dependency graph changes that it has
|
|
// done.
