| Construct a decoder object.
| xref:BloombergLP/balber/BerDecoder/2destructor.adoc[`~BerDecoder`] [.small]#[destructor]#
| Destroy this object. This destruction has no effect on objects pointed‐to by the pointers provided at construction.
| xref:BloombergLP/balber/BerDecoder/decode-0d.adoc[`decode`] 
| `decode` overloads
| xref:BloombergLP/balber/BerDecoder/decodeAny-05.adoc[`decodeAny`] 
| `decodeAny` overloads
| xref:BloombergLP/balber/BerDecoder/decoderOptions.adoc[`decoderOptions`] 
| Return the address of the BER decoder options.
| xref:BloombergLP/balber/BerDecoder/errorSeverity-03.adoc[`errorSeverity`] 
| Return the severity of the most severe log or error message encountered during the last call to the `decode` method.
| xref:BloombergLP/balber/BerDecoder/loggedMessages.adoc[`loggedMessages`] 
| Return a string containing any error or trace messages that were logged during the last call to the `decode` method. The log is reset each time `decode` is called.

| Return 'true' if the maximum depth level is exceeded and 'false' otherwise.
| xref:BloombergLP/balber/BerDecoder/numUnknownElementsSkipped.adoc[`numUnknownElementsSkipped`] 
| Return the number of unknown elements that were skipped during the previous decoding operation.
| xref:BloombergLP/balber/BerDecoder/setNumUnknownElementsSkipped.adoc[`setNumUnknownElementsSkipped`] 
| Set the number of unknown elements skipped by the decoder during the current decoding operation to the specified `value`.
