Constructor Detail

HDon

public HDon()

Creates a new, empty HDon descriptor.

HDon

public HDon(HBParameters params)

Creates a new instance according to the parameters given.

Parameters:

params - parameters

HDon

public HDon(String params)

Creates a new instance according to the parameters given.

Parameters:

params - parameter settings

HDon

public HDon(ScalarDescriptor sd)

Copy constructor. An identical copy of the ScalarDescriptor passed is created. The old and the new instances share the same HBParameters object.

Parameters:

sd - a descriptor to be copied

Method Detail

clone

public MolecularDescriptor clone()

Creates a new instance with identical internal state.

Overrides:

clone in class ScalarDescriptor

Returns:

the newly copied object

getName

public String getName()

Gets the name of the HDon descriptor object. The name is not the same as the class name, but nicer, and more meaningful for end-users too.

Overrides:

getName in class ScalarDescriptor

Returns:

the nice, external name for HDon descriptor class objects

getShortName

public String getShortName()

Gets the short name of the descriptor.

Overrides:

getShortName in class ScalarDescriptor

Returns:

the short name used in text outputs (tables etc.)

setParameters

public void setParameters(String parameters)
                   throws MDParametersException

Sets the parameters of an already created HDon object.

Overrides:

setParameters in class ScalarDescriptor

Parameters:

parameters - parameter settings for the descriptor

Throws:

MDParametersException - any XML error

getParametersClassName

public String getParametersClassName()

Gets the name of the parameters class corresponding to the descriptor.

Overrides:

getParametersClassName in class ScalarDescriptor

Returns:

the name of the parameters class

generate

public String[] generate(Molecule m)
                  throws MDGeneratorException

Creates the HDon descriptor for the given Molecule. Calls the generator created by the corresponding HBParameters class.

Overrides:

generate in class ScalarDescriptor

Returns:

property names set in the molecule passed during generation

Throws:

MDGeneratorException - when failed to generate descriptor
