      public IsProtonInConjugatedPiSystemDescriptor()
      Constructor for the IsProtonInConjugatedPiSystemDescriptor object

  • Method Details

    • getSpecification

      public DescriptorSpecification getSpecification()
      Gets the specification attribute of the IsProtonInConjugatedPiSystemDescriptor object
      Specified by:

    • getDescriptorNames

      public String[] getDescriptorNames()
      Description copied from interface: IDescriptor
      Returns an array of names for each descriptor value calculated. Many descriptors return multiple values. In general it is useful for the descriptor to indicate the names for each value. In many cases, these names can be as simple as X1, X2, ..., XN where X is a prefix and 1, 2, ..., N are the indices. On the other hand it is also possible to return other arbitrary names, which should be documented in the Javadocs for the descriptor (e.g., the CPSA descriptor). Note that by default if a descriptor returns a single value (such as ALOGPDescriptor the return array will have a single element
      Specified by:
      getDescriptorNames in interface IDescriptor
      Returns:
      An array of descriptor names, equal in length to the number of descriptor calculated..
