  • Method Details

    • contains

      boolean contains(Address addr)
      Test if the address is contained within this set.

      Parameters:
      addr - address to test.
      Returns:
      true if addr exists in the set, false otherwise.

    • contains

      boolean contains(Address start, Address end)
      Test if the given address range is contained in this set. The specified start and end addresses must form a valid range within a single AddressSpace.

      Parameters:
      start - the first address in the range.
      end - the last address in the range.
      Returns:
      true if entire range is contained within the set, false otherwise.

    • contains

      boolean contains(AddressSetView rangeSet)
      Test if the given address set is a subset of this set.

      Parameters:
      rangeSet - the set to test.
      Returns:
      true if the entire set is contained within this set, false otherwise.

    • isEmpty

      boolean isEmpty()
      Returns:
      true if this set is empty.

    • getMinAddress

      Address getMinAddress()
      Get the minimum address for this address set. NOTE: An AddressRange should generally not be formed using this address and getMaxAddress() since it may span multiple AddressSpaces.
      Returns:
      the minimum address for this set. Returns null if the set is empty.

    • getMaxAddress

      Address getMaxAddress()
      Get the maximum address for this address set. NOTE: An AddressRange should generally not be formed using this address and getMaxAddress() since it may span multiple AddressSpaces.
