Package com.actelion.research.chem.descriptor

Class DescriptorHandlerIntVector<U>

java.lang.Object

com.actelion.research.chem.descriptor.DescriptorHandlerIntVector<U>

All Implemented Interfaces:

DescriptorHandler<int[],U>, ISimilarityCalculator<int[]>

public class DescriptorHandlerIntVector<U>
extends java.lang.Object
implements DescriptorHandler<int[],U>

This is a descriptor handler, where the input object is an integer array that typically represents counts of some sort. This class may be used if input objects are more complex and the descriptors derived from them can be represented as integer vectors.
This class provides similarity calculation and descriptor en- and decoding.
