Constructor & Destructor Documentation

__init__()

None CDPL.Descr.BurdenMatrixGenerator.__init__	(	Chem.MolecularGraph	molgraph,
		Math.DMatrix	mtx
	)

Constructs the BCUTDescriptorGenerator instance and generates the Burden matrix of the molecular graph molgraph.

Parameters

molgraph	The molecular graph for which to generate the Burden matrix.
mtx	The generated Burden matrix of the specified molecular graph.

Member Function Documentation

getObjectID()

int CDPL.Descr.BurdenMatrixGenerator.getObjectID

(

)

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

Different Python BurdenMatrixGenerator 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 BurdenMatrixGenerator 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.

setAtomWeightFunction()

None CDPL.Descr.BurdenMatrixGenerator.setAtomWeightFunction

(

ForceField.MMFF94AtomChargeFunction

func

)

Allows to specify a custom atom weight function for the diagonal elements of the Burden matrix.

Parameters

func	A BurdenMatrixGenerator.AtomWeightFunction instance that wraps the target function.

Note

By default, the diagonal elements of the Burden matrix are atom types (see namespace Chem.AtomType).

generate()

None CDPL.Descr.BurdenMatrixGenerator.generate	(	Chem.MolecularGraph	molgraph,
		Math.DMatrix	mtx
	)

Generates the Burden matrix of the molecular graph molgraph.

Parameters

molgraph	The molecular graph for which to generate the Burden matrix.
mtx	The generated Burden matrix of the specified molecular graph.
