Method Details

getOptionDescriptors

protected void getOptionDescriptors(String fmtname,
 String optnames,
 List<OptionDescriptor> l)

Gets the option descriptors.

Overrides:

getOptionDescriptors in class MolExportModule

Parameters:

fmtname - the format name or null

optnames - option names or null for all

l - the output list

Since:

Marvin 5.0, 06/06/2007

open

public Object open(String fmtopts,
 MPropertyContainer props)
            throws MolExportException

Open the exporter stream.

Overrides:

open in class MolExportModule

Parameters:

fmtopts - output file format and options

props - the gui options or null (ignored parameter)

Returns:

the head of the file for RDF, null otherwise

Throws:

MolExportException - Invalid format string.

parseOption

protected int parseOption(String opts,
 int i)
                   throws IllegalArgumentException

Parses the bond length (b###) option.

Overrides:

parseOption in class MolExportModule

Parameters:

opts - the options string

i - the current index

Returns:

index of the next option, or i if the current option is unknown

Throws:

IllegalArgumentException - in case of parsing error

convert

public Object convert(Molecule mol)
               throws MolExportException

Creates an MDL mol or compressed mol representation of the molecule. If the molecule source is in 0D, then cleans the moelcule in 2D before exporting it, since 0D olfiles cannot contains stereo information. This cleaning was introduced in Marvin 5.4, and can be omit by adding "omitClean0D" to the format options.

Specified by:

convert in class MolExportModule

Parameters:

mol - the molecule

Returns:

a string containing the molfile

Throws:

MolExportException - cannot be converted to MDL molfile

getMolfileVersion

protected int getMolfileVersion()

Gets the molfile version.

Returns:

2 or 3

Since:

Marvin 3.4.1, 07/16/2004

appendMEnd

protected void appendMEnd()

Appends the "M END" line to the string buffer.

convertPageSettingsToData

protected void convertPageSettingsToData(Molecule mol)

Converts page setting of multipage molecular document to data sgroups (attached data) with field name MRV_PAGE_XXX. The data is attached to the first atom.

Parameters:

mol - molecule to convert

Since:

Marvin 4.1 02/14/2006

convertCoordinateBondsToData

protected void convertCoordinateBondsToData(Molecule molecule)

Converts coordinate bonds to data sgroups (attached data) with field name MRV_COORDINATE_BOND. The data is attached to the first atom.

Parameters:

molecule - molecule to convert
