<h1>[name]</h1>
<p class="desc">
Abstract base class of interpolants over parametric samples.<br /><br />
The parameter domain is one dimensional, typically the time or a path along a curve defined by the data.<br /><br />
The sample values can have any dimensionality and derived classes may apply special interpretations to the data.<br /><br />
This class provides the interval seek in a Template Method, deferring the actual interpolation to derived classes.<br /><br />
Time complexity is *O(1)* for linear access crossing at most two points and *O(log N)* for random access,
where *N* is the number of positions.<br /><br />

<h3>[name]( parameterPositions, sampleValues, sampleSize, resultBuffer )</h3>
<p>
parameterPositions -- array of positions<br />
sampleValues -- array of samples<br />
sampleSize -- number of samples<br />
resultBuffer -- buffer to store the interpolation results.<br /><br />
Note: This is not designed to be called directly.
