A Python class is generated for an ASN.1 BOOLEAN type only if the type is tagged. This is only true for BER/DER encoding rules; in other cases, no class is generated.

If a class is generated, it will contain static methods for the BER encoding or decoding of a boolean value.

Example ASN.1:

B ::= [APPLICATION 2] BOOLEAN

Generated Python Class:

class B:
    @staticmethod
    def ber_decode(decbuf, explicit=True, impllen=None):
    ...

    @staticmethod
    def ber_encode(value, encbuf, explicit=True):
    ...

The value that is returned by the decode method or passed into the encode method is a Python boolean value (True or False).

See the BER encode/decode methods for information on how to call these methods.
