Bit deserializer.

This class helps converting a variable number, variable sized number of bit-boundary fields stored as byte array representation and extract the original bit-fields.
Note that once the Deserialization starts, it's not anymore possible to add more data to the byte blob to deserialize.

uint64_t ns3::BitDeserializer::GetBits | ( | uint8_t | size | ) |
Pops a given number of bits from the blob front.
In other terms, 'size' bits are shifted from the contents of the byte blob onto the return value.
The maximum number of bits to be deserialized in one single call is 64.
size | The number of bits to pop. |
