It takes two connection objects, a boolean (`isDragging`) indicating if a block is being dragged, and an optional `opt_distance` parameter for drag distance checks. It returns a boolean value indicating whether the connection between the provided connections is permitted. The method determines if it's valid for connections 'a' and 'b' to be linked.\n"]]
