<div>These are not exposed in the API, as the API is abstracted from the encoding details which change frequently. </div>
<div><br>
</div>
<div>May I ask why your application needs to know, for example, the MetaInfo encoding length? Maybe we can find a way to meet your application needs. (The API provides some mechanism for manipulating TLV encodings.)</div>
