    • FvParameters

      public FvParameters(FvParameters.Builder builder)
      Constructor based on a builder.
      Parameters:
      builder - Builder which current state will be represented.

    • FvParameters

      public FvParameters()
      Construct with default values.

  • Method Details

    • 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:
      Fingerprint length

    • getNumericRepresentation

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

    • getSparseCompression

      public FvParameters.SparseCompression getSparseCompression()
      Sparse compression.
      Returns:
      Optimization for sparse vectors.

    • getScaledMax

      public double getScaledMax()
      Max value for scaled fixed point representations.
      Returns:
      max value

    • getScaledMin

      public double getScaledMin()
      Min value for scaled fixed point representations.
      Returns:
      min value
