  - getDescriptorGenerator
```
public FvGenerator 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
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - createNewBuilder
```
public static FvParameters.Builder createNewBuilder()
```
    Construct a builder for this parameter class, initialized to default.
    
    Returns:
    
    Builder initialized to default settings
  - getLength
```
public int getLength()
```
    Returns represented fingerprint length (bit count) setting.
    
    Returns:

  - getNumericRepresentation
```
public FvParameters.NumericRepresentation getNumericRepresentation()
```
    Numeric representation.
    
    Returns:
    
    Numeric representation of underlying vector
