Constructor Detail

HAcc

public HAcc()

Creates a new, empty HAcc descriptor.

HAcc

public HAcc(HBParameters params)

Creates a new instance according to the parameters given.

Parameters:

params - parameters

HAcc

public HAcc(java.lang.String params)

Creates a new instance according to the parameters given.

Parameters:

params - parameter settings

HAcc

public HAcc(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 HAcc clone()

Creates a new instance with identical internal state.

Overrides:

clone in class ScalarDescriptor

Returns:

the newly copied object

getName

public java.lang.String getName()

Gets the name of the HAcc 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 HAcc descriptor class objects

getShortName

public java.lang.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(java.lang.String parameters)
                   throws MDParametersException

Sets the parameters of an already created HAcc object.

Overrides:

setParameters in class ScalarDescriptor

Parameters:

parameters - parameter settings for the descriptor

Throws:

MDParametersException - any XML error

getParametersClassName

public java.lang.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 java.lang.String[] generate(Molecule m)
                            throws MDGeneratorException

Calculates the HAcc 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
