maybe_BER()

bool Botan::ASN1::maybe_BER

(

DataSource &

src

)

Heuristics tests; is this object possibly BER?

Parameters

src	a data source that will be peeked at but not modified

Definition at line 219 of file asn1_obj.cpp.

   uint8_t first_u8;
   if(!source.peek_byte(first_u8))

      BOTAN_ASSERT_EQUAL(source.read_byte(first_u8), 0, "Expected EOF");
      throw Stream_IO_Error("ASN1::maybe_BER: Source was empty");
      }

   if(first_u8 == (SEQUENCE | CONSTRUCTED))
      return true;
   return false;
