      • MemoryDiff

        public MemoryDiff​(Program p1,
                  Program p2)
           throws ProgramConflictException
        Constructs an object for determining memory differences between two programs.
        Parameters:
        p1 - the first program
        p2 - the second program
        Throws:
        ProgramConflictException - if the program memory can't be compared because the programs are based on different languages.

        the second program

      • getNumRanges

        public int getNumRanges()
        Gets the number of address ranges that the two programs memories are broken into for comparing the programs.
        Returns:
        the number of address ranges.

      • getRange

        public AddressRange getRange​(int index)
        Gets the address range as indicated by index. The index is zero based. Address ranges are in order from the minimum address to the maximum address range.
        Parameters:
        index - the index of the address range to get.
        Returns:
        the address range.

        Gets the memory difference flags for the address range as indicated by index.
        Parameters:
        index - the index of the address range to get the difference flags for.
        Returns:
        the difference flags for the indicated address range.

      • getDifferences

        public java.lang.String getDifferences​(Address p1Address)
        Gets a string representation of the types of memory differences that exist for the memory block that contains the indicated address.
        Parameters:
        p1Address - address that is obtained via the first program.
        Returns:
        a string indicating the types of memory differences.

      • getDifferentAddressRanges

        public AddressRange[] getDifferentAddressRanges()
        Returns an array of address ranges where there are memory differences.
        Returns:
        address ranges with differences.
