SGROUP_TYPENAMES

public static final String[] SGROUP_TYPENAMES

Array of S-group type names.

Constructor Detail

MolfileUtil

public MolfileUtil()

Method Detail

getSgroupType

public static Integer getSgroupType(String name)

Gets the S-group type.

Parameters:

name - the S-group type name

Returns:

the type or null for invalid type name

isSpecBeilsteinGeneric

public static boolean isSpecBeilsteinGeneric(String s)

Tests whether the specified symbol is a Beilstein Generic except A, Q and X.

Parameters:

s - the S-group type name

Returns:

the type or null for invalid type name

decodeHIsotopeMass

public static int decodeHIsotopeMass(int code)

Extract H isotope information from the given Chemaxon compressed mol format code of the atom.

Parameters:

code - given code

Returns:

the mass number stored in the code

codeHIsotopeMass

public static int codeHIsotopeMass(int originalCode,
                                   int massNo)

Add mass number information to the given code. Utility for compressed mol format coding of H isotopes.

Parameters:

originalCode - the code to which mass number is added

massNo - the mass number

Returns:

the modified code

MDLCT2MDL

public static final byte[] MDLCT2MDL(byte[] data)
                              throws IOException

Converts an MDLCT data to MDL. MDLCT format: sequence of records where each record is a C like String. Each record stores a line of the molfile (without EOL character). The first byte describes how many bytes are allocated for the string. The MDLCT stream starts with a zero byte since Mol file starts with an empty line.

Parameters:

data - the clipboard transferable MDL bytes

Returns:

an MDL file as a byte array

Throws:

IOException
