Method Detail

setOptions

public void setOptions(java.lang.String opts)

Sets the import options.

Overrides:

setOptions in class MolImportModule

Parameters:

opts - import options

initMolImport

public void initMolImport(MolInputStream is)
                   throws MolFormatException,
                          java.io.IOException

Initializes the import module.

Overrides:

initMolImport in class MolImportModule

Parameters:

is - the molecule input stream

Throws:

MolFormatException - if the file cannot be read because of a molecule file format related error

java.io.IOException - an I/O error occurred while reading the file

readMol

public boolean readMol(Molecule mol)
                throws MolFormatException,
                       java.io.IOException

Reads a molecule from MDL mol/sdf/rxn file. All the nodes, edges, and properties are removed from mol before reading.

Specified by:

readMol in class MolImportModule

Parameters:

mol - the molecule object to read into

Returns:

true after successfully reading the molecule, false if no more molecule found

Throws:

MolFormatException - if the file is in bad format

java.io.IOException - in case of I/O error

createMol

public Molecule createMol()

Creates a new target molecule object.

Specified by:

createMol in class MolImportModule

Returns:

new Molecule, RgMolecule or RxnMolecule
