Class AddressSetViewAdapter

java.lang.Object
ghidra.program.model.address.AddressSetViewAdapter
All Implemented Interfaces:
AddressSetView, Iterable<AddressRange>
public class AddressSetViewAdapter extends Object implements AddressSetView
This class wraps an address set and provides read-only access to that set. This class is used to ensure that users can not violate the read-only access by casting the object to an address set.
