    • Method Detail

      • getKey

        long getKey​(Address addr,
                    boolean create)
        Get the database key associated with the given relative address. This key uniquely identifies a relative location within the program. If the program's image base is moved to another address, this key will map to a new address that is the same distance to the new base as the old address was to the old base. If the requested key does not exist and create is false, INVALID_ADDRESS_KEY will be returned. Note that nothing should ever be stored using the returned key unless create is true.
        Parameters:
        addr - the address for which to get a database key.
        create - true if a new key may be generated
        Returns:
        the database key for the given address or INVALID_ADDRESS_KEY if create is false and one does not exist for the specified addr.
      • getAbsoluteEncoding

        long getAbsoluteEncoding​(Address addr,
                                 boolean create)
        Get the database key associated with the given absolute address. This key uniquely identifies an absolute location within the program. If the requested key does not exist and create is false, INVALID_ADDRESS_KEY will be returned. Note that nothing should ever be stored using the returned key unless create is true.
        Parameters:
        addr - the address for which to get a database key.
        create - true if a new key may be generated
        Returns:
        the database key for the given address or INVALID_ADDRESS_KEY if create is false and one does not exist for the specified addr.
      • findKeyRange

        int findKeyRange​(java.util.List<KeyRange> keyRangeList,
                         Address addr)
        Search for addr within the "sorted" keyRangeList and return the index of the keyRange which contains the specified addr.
        Parameters:
        keyRangeList - key range list to search
        addr - address or null
        Returns:
        index of the keyRange within the keyRangeList which contains addr if it is contained in the list; otherwise, (-(insertion point) - 1). The insertion point is defined as the point at which the addr would be inserted into the list: the index of the first keyRange greater than addr, or keyRangeList.size(), if all keyRanges in the list are less than the specified addr. Note that this guarantees that the return value will be >= 0 if and only if the addr is found within a keyRange. An addr of null will always result in a returned index of -1.
      • getKeyRanges

        java.util.List<KeyRange> getKeyRanges​(Address start,
                                              Address end,
                                              boolean create)
        Generates a properly ordered list of database key ranges for a a specified address range. If absolute encodings are requested, only memory addresses will be included. Returned key ranges are generally intended for read-only operations since new keys will never be generated. The returned key ranges will correspond to those key ranges which have previously been created within the specified address range and may represent a much smaller subset of addresses within the specified range.
        Parameters:
        start - minimum address of range
        end - maximum address of range
        create - true if a new keys may be generated, otherwise returned key-ranges will be limited to those already defined.
        Returns:
        "sorted" list of KeyRange objects

        Generates a properly ordered list of database key ranges for a a specified address set. If absolute encodings are requested, only memory addresses will be included.
        Parameters:
        set - address set or null for all addresses. May not be null if create is true.
        create - true if a new keys may be generated, otherwise returned key-ranges will be limited to those already defined.

      • decodeAddress

        Address decodeAddress​(long value)
        Returns the address that was used to generate the given long key. (If the image base was moved, then a different address is returned unless the value was encoded using the "absoluteEncoding" method. If the program's default address space is segmented (i.e., SegmentedAddressSpace). the address returned will be always be normalized to defined segmented memory blocks if possible.
        Parameters:
        value - the long value to convert to an address.
        Returns:
        address decoded from long
      • getAddressFactory

        AddressFactory getAddressFactory()
        Returns the address factory associated with this map. Null may be returned if map not associated with a specific address factory.
