Class MoleculeImporter

java.lang.Object

chemaxon.marvin.io.formats.MoleculeImporter

All Implemented Interfaces:

chemaxon.marvin.io.formats.MoleculeImporterIface

@PublicAPI
public class MoleculeImporter
extends Object
implements chemaxon.marvin.io.formats.MoleculeImporterIface

Molecule importer. Wrapper for MolImporter. Can only read the stream forward (not seekable stream). In some cases (mrv, cml) it can be faster than MolImporter.

The input file format is guessed automatically or specified as an import option to the constructor. Many different formats are supported like "mol", "rgf", "sdf", "rdf", "csmol", "csrgf", "cssdf", "csrdf", "mol2", "cml", "mrv", "smiles", "cxsmiles", "pdb", "xyz", "cube", "name". For more information on formats, please visit File Formats in Marvin.

Marvin 5.7

The wrapped importer. Created in the constructor, the interface methods delegates the functionality to this importer.

Constructor Detail

MoleculeImporter

public MoleculeImporter(String fileName)
                 throws IOException

Constructs a new importer for the file.

Parameters:

fileName - the name of the file to import.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(String fileName,
                        String opts)
                 throws IOException

Constructs a new importer for the file.

Parameters:

fileName - the name of the file to import.

opts - the file format and options separated by a colon. Autorecognition is called if null or format is not specified.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(File f)
                 throws IOException

Constructs a new importer for the file.

Parameters:

f - the file to import.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(File f,
                        String opts)
                 throws IOException

Constructs a new importer for the file.

Parameters:

f - the file to import.

opts - the file format and options separated by a colon. Autorecognition is called if null or format is not specified.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(InputStream inputStream)
                 throws IOException

Constructs a new importer for the input stream.

Parameters:

inputStream - the stream to import from.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(InputStream inputStream,
                        String opts)
                 throws IOException

Constructs a new importer for the stream.

Parameters:

inputStream - the stream to import from.

opts - the file format and options separated by a colon. Autorecognition is called if null or format is not specified.

Throws:

IOException - if an I/O error occurs.

MoleculeImporter

public MoleculeImporter(InputStream inputStream,
