Detailed Description

This class contains a collection of static functions for calculating the streamed length of simple types when using DescriptorIO, FileIO and StreamedIO.

It also contains functions for calculating the streamed length of strings, deques, lists, vectors, maps, multimaps, sets, multisets, unordered_maps, unordered_multimaps, unordered_sets, unordered_multisets, tuples and variants. We use our member functions to handle simple types in the containers, and function templates to handle other class types. User-defined classes must implement the StreamedLengthCapable interface, since the function templates simply call out to it.

Member Function Documentation

StreamedLength() [1/2]

static uint64_t Dwm::IOUtils::StreamedLength ( char c )

inlinestatic

Returns the number of bytes that would be written if we called Write() for a char.

Should always be 1.

StreamedLength() [2/2]

static uint64_t Dwm::IOUtils::StreamedLength ( uint8_t c )

inlinestatic

Returns the number of bytes that would be written if we called Write() for a uint8_t.

Should always be 1.
