An interface for writing data objects of type Chem.MolecularGraph to an arbitrary data sink.
MolecularGraphWriterBase is the common interface of classes which write objects of type Chem.MolecularGraph to some data sink (e.g. a file) that expects the data to be encoded in a particular storage format.
From the MolecularGraphWriterBase interface point of view, the data sink is continuous output stream in which the data objects are written as data records. For the output of a given data object the method write() has to be called with the object passed as an argument.
If the write() operation fails, the writer instance is set into an error state that can be queried by the special methods bool() and nonzero(). Additionally, a MolecularGraphWriterBase implementation may decide to throw an exception of type Base.IOError to report the error condition.
| MolecularGraphWriterBase CDPL.Chem.MolecularGraphWriterBase.write | ( | MolecularGraph | molgraph | ) |
Writes the MolecularGraph object molgraph.
| molgraph | The MolecularGraph object to write. |
| Base.IOError | if an I/O error occurred. |
| None CDPL.Chem.MolecularGraphWriterBase.close | ( | ) |
Writes format dependent data (if required) to mark the end of output.
| Base.IOError | if an I/O error occurred. |
