Constructor Details

TPSA

public TPSA()

Creates a new, empty logD descriptor.

TPSA

public TPSA(SDParameters params)

Creates a new instance according to the parameters given.

Parameters:

params - parameters

TPSA

public TPSA(String params)

Creates a new instance according to the parameters given.

Parameters:

params - parameter settings

TPSA

public TPSA(ScalarDescriptor sd)

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

Parameters:

sd - a fingerprint to be copied

Method Details

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 TPSA 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 logD 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 TPSA object.

Overrides:

setParameters in class ScalarDescriptor

Parameters:

parameters - parameter settings for the descriptor

Throws:

MDParametersException - any XML error

needsConfig

public boolean needsConfig()

Indicates if class takes parameters from configuration file.

Overrides:

needsConfig in class MolecularDescriptor

Returns:

false

generate

public String[] generate(Molecule m)
                  throws MDGeneratorException

Creates the TPSA descriptor for the given Molecule. Calls the generator created by the corresponding TPSAParameters class.

Overrides:

generate in class ScalarDescriptor

Returns:

property names set in the molecule passed during generation

Throws:

MDGeneratorException - when failed to generate descriptor
