ns3::BitSerializer

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.

Member Function Documentation

GetBits()

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.

Parameters

size	The number of bits to pop.

Returns

The popped bits value
