DissimilarityCalculator (com.chemaxon.plexus.core:plexus-dif-api)

```
public interface DissimilarityCalculator
```
Dissimilarity calculator for calculating dissimilarity between query and target molecule. Can be registered as a NetBeans service and create(com.im.df.api.ddl.DFEntity, chemaxon.struc.Molecule, chemaxon.sss.search.JChemSearchOptions, chemaxon.standardizer.Standardizer) itself.

Since:

20.18.0

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`float`	`calculateDissimilarity(chemaxon.struc.Molecule target)`	Calculates dissimilarity score between the previously set query and the provided target molecule.
`default DissimilarityCalculator`	`create(DFEntity targetEntity, chemaxon.struc.Molecule query, chemaxon.sss.search.JChemSearchOptions options, chemaxon.standardizer.Standardizer standardizer)`	Creates an instance of `DissimilarityCalculator` for given `targetEntity` type.

default DissimilarityCalculator create(DFEntity targetEntity,
                                       chemaxon.struc.Molecule query,
                                       chemaxon.sss.search.JChemSearchOptions options,
                                       chemaxon.standardizer.Standardizer standardizer)
```
    Creates an instance of DissimilarityCalculator for given targetEntity type.
    
    Parameters:
    
    targetEntity - target entity - JChem Base, JPC, ...
    
    query - query molecule - stored for later calculation with target molecule
    
    options - JChem search options
    
    standardizer - standardizer, can be null
    
    Returns:
    
    instance of DissimilarityCalculator or null if calculator does not fit the targetEntity type

float calculateDissimilarity(chemaxon.struc.Molecule target)
                      throws chemaxon.descriptors.MDGeneratorException
```
    Calculates dissimilarity score between the previously set query and the provided target molecule.
    
    Parameters:
    
    target - Molecule to compare with query
    
    Returns:
    
    dissimilarity between query and target
    
    Throws:
    
    chemaxon.descriptors.MDGeneratorException - if failed to generate descriptor.
