Method Details

getDescriptorGenerator

public EcfpGenerator getDescriptorGenerator()

Description copied from interface: DescriptorParameters

Return the represented descriptor generator.

Please note that certain descriptors might provide multiple DescriptorGenerator implementations for different descriptor representations. (Consider structure based fingerprints feature list/feature counts/folded finite binary vector representations.) Such different descriptor generators might be exposed through their parameters object as multiple factory methods.

Specified by:

getDescriptorGenerator in interface DescriptorParameters

Returns:

Associated generator

createNewBuilder

public static EcfpParameters.Builder createNewBuilder()

Construct a builder for this parameter class, initialized to default.

Returns:

Builder initialized to default settings

toString

public String toString()

Overrides:

toString in class Object

getDiameter

public int getDiameter()

The maximum diameter of the circular neighborhoods.

Returns:

Diameter considered

getLength

public int getLength()

Returns represented fingerprint length (bit count) setting.

Returns:

Fingerprint length

getAtomTypizer

public EcfpAtomTypizers getAtomTypizer()

Atom typizer to use.

Returns:

Atom typizer to use

getIdentifierConfigurationXml

public Optional<String> getIdentifierConfigurationXml()

Identifier configuration for {@link
