    Description copied from interface: Evidence
    
    Cast this evidence type and apply a function if the type matches.
    
    Specified by:
    
    castAndApply in interface Evidence
    
    Type Parameters:
    
    E - the evidence type
    
    R - the return type
    
    Parameters:
    
    evidenceType - the evidence type class to check
    
    algorithmName - the name of the algorithm or null if any algorithm is acceptable
    
    function - the function to apply
    
    Returns:
    
    the result of the function, or null if the evidence is not of the given type
