public interface DissimilarityInput
```
DissimilarityInput represents an input set for similarity based clustering algorithm. See MolInputBuilder for an implementation.
This abstraction is used when pairwise comparison of inputs is required by a certain algorithm.

Please note that this interface is marked with Beta annotation, so it can be subject of incompatible changes or removal in later releases.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`double`	`dissimilarity(int targetIndex, int queryIndex)`	Dissimilarity/distance between an ordered pair of input items.
`MetricMetadata`	`getMetricMetadata()`	Metadata about the underlying metric.
`int`	`size()`	Item count to be considered.

- Method Detail
  - size
```
int size()
```
    Item count to be considered.
    
    Returns:
    
    Item count
  - dissimilarity
```
double dissimilarity(int targetIndex,
                     int queryIndex)
```
    Dissimilarity/distance between an ordered pair of input items.
    Please note that the represented input is not necessarily a metric space; only the satisfactions of criteria described by the results of getMetricMetadata() is guaranteed.
    
    Note that parameter naming discriminates query and target indexes to be consistent with the usage of non symmetric underlying comparison metrics.
    
    Parameters:
    
    targetIndex - Index of first item to be compared
    
    queryIndex - Index of second item to be compared
    
    Returns:
    
    Dissimilarity of the two compared items
    
    Throws:
    
    IllegalArgumentException - when either of the idem indexes passed is negative or greater or equal to item count returned by size()
  - getMetricMetadata
```
MetricMetadata getMetricMetadata()
```
    Metadata about the underlying metric.
    
    Returns:
    
    Metadata of the comparison of dissimilarity calculations
