Typically, Builder objects will be used from code generated by the `flatc` compiler. A Builder constructs byte buffers in a last-first manner for simplicity and performance during reading. Internally, a Builder is a state machine for creating FlatBuffer objects. It holds the following internal state: - Bytes: an array of bytes. - current_vtable: a list of integers. - vtables: a hash of vtable entries. Attributes: Bytes: The internal `bytearray` for the Builder. finished: A boolean determining if the Builder has been finalized. ) Bytescurrent_vtableheadminalign objectEndvtablesnested forceDefaultsfinishedvectorNumElems sharedStringslcd|cxkrtjksnd}t|t||_d|_t j||_d|_ d|_ i|_ d|_ d|_ d|_d|_y)z_Initializes a Builder of size `initial_size`.

This is the typical way to access the FlatBuffer data inside the builder. If you try to access `Builder.Bytes` directly, you would need to manually index it with `Head()`, since the buffer is constructed backwards. It raises BuilderNotFinishedError if the buffer has not been finished with `Finish`.

Before writing out the vtable, this checks pre-existing vtables for equality to this one. If an equal vtable is found, point the object to the existing vtable and return. Because vtable values are sensitive to alignment of object data, not all logically-equal vtables will be deduplicated. A vtable has the following format: * N, where N is the number of fields in the schema for this type. Includes deprecated fields. Thus, a vtable is made of 2 + N elements, each VOffsetT bytes wide.
