    • Method Detail

      • atomTypeMatching

        public McsSearchOptions.Builder atomTypeMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether atom types should be considered in search. By default, the atom types are checked, i.e., a carbon atom does not match to an oxygen atom.
        Specified by:
        atomTypeMatching in class MatchingOptions.Builder
        Parameters:
        value - specifies whether atom types are checked (true) or ignored (false)
        Returns:
        this builder

      • bondTypeMatching

        public McsSearchOptions.Builder bondTypeMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether bond types should be considered in search. By default, the bond types are checked, i.e., "CC" does not match to "C=C".
        Specified by:
        bondTypeMatching in class MatchingOptions.Builder
        Parameters:
        value - specifies whether bond types are checked (true) or ignored (false)
        Returns:
        this builder

      • isotopeMatching

        public McsSearchOptions.Builder isotopeMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether isotopes of atoms should be considered in search. By default, mass numbers are ignored, so isotopes of the same element match each other.

        If atom type matching is disabled, isotopes are also ignored, irrespective of this search option.

        Specified by:
        isotopeMatching in class MatchingOptions.Builder
        Parameters:
        value - specifies whether mass numbers are checked (true) or ignored (false)
        Returns:
        this builder

      • radicalMatching

        public McsSearchOptions.Builder radicalMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether the radical information of atoms should be considered in search. By default, radicals are ignored.
        Specified by:
        radicalMatching in class MatchingOptions.Builder
        Parameters:
        value - specifies whether radicals are checked (true) or ignored (false)
        Returns:
        this builder

      • atomMapMatching

        public McsSearchOptions.Builder atomMapMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether atom map numbers should be considered in search. If set to true, two atoms with different map numbers do not match each other. By default, it is set to false.
        Specified by:
        atomMapMatching in class MatchingOptions.Builder
        Parameters:
        value - specifies whether atom map numbers are checked (true) or ignored (false)
        Returns:
        this builder

      • exactQueryAtomMatching

        public McsSearchOptions.Builder exactQueryAtomMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether generic query atoms should be matched only to atoms of exactly the same type. If set to true, generic atoms are not considered as query features. For example, an "any" atom matches only to another "any" atom. By default, it is set to false.
        Specified by:
        exactQueryAtomMatching in class MatchingOptions.Builder
        Parameters:
        value - true if generic query atoms should match only atoms of exactly the same type
        Returns:
        this builder

      • exactQueryBondMatching

        public McsSearchOptions.Builder exactQueryBondMatching​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether generic query bonds should be matched only to bonds of exactly the same type. If set to true, generic bonds are not considered as query features. For example, an "any" bond matches only to another "any" bond. By default, it is set to false.
        Specified by:
        exactQueryBondMatching in class MatchingOptions.Builder
        Parameters:
        value - true if generic query bonds should match only bonds of exactly the same type
        Returns:
        this builder

      • maxConsideredRingSize

        public McsSearchOptions.Builder maxConsideredRingSize​(int value)
        Sets the maximum size of rings considered for ring matching purposes. The default value is 8. (A ring of 9 or more atoms is considered a macrocycle.)
        Parameters:
        value - the maximum considered ring size
        Returns:
        this builder
        See Also:
        ringHandlingMode(RingHandlingMode)

      • connectedMode

        public McsSearchOptions.Builder connectedMode​(boolean connected)
        Sets whether the common substructures should be connected or they can consist of multiple fragments.
        Parameters:
        connected - specifies if connected common substructures should be found (true) or disconnected substructures are also allowed (false)
        Returns:
        this builder
        See Also:
        minFragmentSize(int)

      • minFragmentSize

        public McsSearchOptions.Builder minFragmentSize​(int bondCount)
        Sets the minimum required size of the fragments of MCS. Fragments having less bonds than this limit are ignored, except for one largest fragment found. The default value is 1 (that is, all fragments are kept).
        Parameters:
        bondCount - minimum required bond count in additional fragments (except for the largest one)
        Returns:
        this builder
        See Also:
        connectedMode(boolean)

      • orderSensitive

        public McsSearchOptions.Builder orderSensitive​(boolean value)
        Description copied from class: MatchingOptions.Builder
        Sets whether search is sensitive to the order of the matched atoms and bonds when searching for multiple results.

        By default, this option is set to false. It means that two search results are considered to be different only when they cover different atoms or bonds of the query or the target. In contrast, order sensitive search differentiates two results with the same set of mapped atoms and bonds in both molecules if the actual mappings are different.

        For example, if the query molecule is "CNC" and target molecule is "CNCNC", then order sensitive search provides four different mappings of the query to the target, while order insensitive (default) search provides only two of these hits (that cover different parts of the target molecule).

        Warning: Order sensitive search may produce orders of magnitude more hits as it also deals with the internal symmetry of the molecules.

        Specified by:
        orderSensitive in class MatchingOptions.Builder
        Parameters:
        value - true if the search should be order sensitive
        Returns:
        this builder

      • customMatching

        public McsSearchOptions.Builder customMatching​(CustomMatcherFactory matcherFactory)
        Description copied from class: MatchingOptions.Builder
        Sets the factory to be used to create a custom matcher. During search, two atom or bonds may be matched only if they are accepted by the corresponding method of the CustomMatcher created by the given factory (in addition to the criteria specified by other search options).
        Specified by:
        customMatching in class MatchingOptions.Builder
        Parameters:
        matcherFactory - the factory for creating the custom matcher to be used
        Returns:
        this builder
