      • DEFAULT_OPTIONS

        static final int DEFAULT_OPTIONS
        Default expansion/contraction options.

        Constant Field Values

      • MDL_EXPAND

        static final int MDL_EXPAND
        MDL like multiple group expansion flag. Coordinates of corresponding atoms in different expanded units are equal. Use this flag for MDL molfile export.

        Constant Field Values

      • LEAVE_COORDS_UNCHANGED

        static final int LEAVE_COORDS_UNCHANGED
        Coordinates are not calculated during expand or contract.

        Constant Field Values

      • NONRECURSIVE_EXPAND

        static final int NONRECURSIVE_EXPAND
        Non recursive expansion of child groups.

      • FAST_COORDS

        static final int FAST_COORDS
        Fast coordinate calculation in expand.

      • COORDS_UPDATE

        @Deprecated
static final int COORDS_UPDATE
        Deprecated.
        As of Marvin 6.2, no replacement.
        Not supported feature.
        Performs coordinate update during the unbinding of atoms. The atom which replaces the unbound atom will take the coordinates of the unbound atom in order preserve the stereo attributes of crossing bonds.
