Detailed Description

A factory interface providing methods for the creation of Chem.MoleculeReaderBase instances for reading data provided in a particular storage format.

Member Function Documentation

◆ getObjectID()

int CDPL.Chem.MoleculeInputHandler.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python MoleculeInputHandler instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two MoleculeInputHandler instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns
The numeric ID of the internally referenced C++ class instance.

◆ getDataFormat()

Base.DataFormat CDPL.Chem.MoleculeInputHandler.getDataFormat ( )

Returns a Base.DataFormat object that provides information about the handled input data format.

Returns
A Base.DataFormat object that provides information about the handled data format.

◆ createReader() [1/2]

MoleculeReaderBase CDPL.Chem.MoleculeInputHandler.createReader ( Base.IStream  is)

Creates a MoleculeReaderBase instance that will read the data from the input stream is.

Parameters
isThe input stream to read from.
Returns
The created MoleculeReaderBase instance.

◆ createReader() [2/2]

MoleculeReaderBase CDPL.Chem.MoleculeInputHandler.createReader ( str  file_name,
OpenMode   mode = Base.IOStream.OpenMode(12) 
)

Creates a MoleculeReaderBase instance that will read the data from the file specified by file_name.

Parameters
file_nameThe full path of the file to read from.
modeFlags specifying the file open-mode.
Returns
The created MoleculeReaderBase instance.
