All Implemented Interfaces:
AddressSetView, Iterable<AddressRange>
Direct Known Subclasses:
ExtCodeBlockImpl, StubMemory
public class AddressSet extends Object implements AddressSetView
Class for storing sets of addresses. This implementation uses a red-black tree where each entry node in the tree stores an address range. The key for an entry node is the minimum address of the range and the value is the maximum address of the range.

  • Constructor Details

    • AddressSet

      public AddressSet()
      Create a new empty Address Set.

    • AddressSet

      public AddressSet(AddressRange range)
      Create a new Address Set from an address range.
      Parameters:
      range - the range of addresses to include in this set.

    • AddressSet

      public AddressSet(Address start, Address end)
      Creates a new Address set containing a single range The specified start and end addresses must form a valid range within a single AddressSpace.
      Parameters:
      start - the start address of the range
      end - the end address of the range
      Throws:
      IllegalArgumentException - if the start and end addresses are in different spaces. To avoid this, use the constructor AddressSet(Program, Address, Address)

    • AddressSet

      public AddressSet(Program program, Address start, Address end)
      Creates a new Address set containing a single range. Use of this method is generally discouraged since the set of addresses between a start and end address not contained within the same AddressSpace may be contain unexpected memory regions.
      Parameters:
      program - the program whose AddressFactory is used to resolve address ranges where the start and end are in different address spaces. If you use the constructor with just the start and end address and the addresses are in different spaces, you would get an IllegalArgumentException.
      start - the start address of the range
      end - the end address of the range

    • AddressSet

      set - Existing Address Set to clone.

    • AddressSet

      public AddressSet(Address addr)
      Create a new Address containing a single address.
