WebFollow is a trait that allows us to access FlatBuffers in a declarative, type safe, and fast way. They compile down to almost no code (after optimizations). Conceptually, Follow lifts the offset-based access patterns of FlatBuffers data into the type system. This trait is used pervasively at read time, to access tables, vtables, vectors ... WebPrepare to write an element of size after additional_bytes have been written, e.g. if you write a string, you need to align such the int length field is aligned to com.google.flatbuffers.Constants#SIZEOF_INT, and the string data follows it directly. If all you need to do is alignment, additional_bytes will be 0.

WebOct 26, 2015 · to Shahbaz Chaudhary, FlatBuffers. You should never have to deal with Offset directly, if you access an element in a Vector, an Offset gets dereferenced into a String *, which has c_str () and str () methods that you can use to access the data (c_str () being more efficient). This is what happens if you call vector … WebThe buffer may have been aligned to any size between. // sizeof (uoffset_t) and FLATBUFFERS_MAX_ALIGNMENT (see "force_align"). // Sadly, the exact alignment is only known when constructing the buffer, // since it depends on the presence of values with said alignment properties. // So instead, we simply look at the next uoffset_t values (root,

You want FlatBufferBuilder::CreateStruct. This is indeed a bit weird compared to how you normally serialize structs (inlined), which is caused by unions wanting all union members to be the same size, so they are referenced over an offset. And you use Union () afterwards, on this newly created struct if I understand correctly. kinetic vision careers
