Member Function Documentation

◆ Flush()

void dart::StreamingWriteStream::Flush ( )

privatevirtual

Definition at line 52 of file datastream.cc.

                                 {
  intptr_t size = current_ - buffer_;
  callback_(callback_data_, buffer_, size);
  flushed_size_ += size;
  current_ = buffer_;
}

◆ Position()

virtual intptr_t dart::StreamingWriteStream::Position ( ) const

inlineprivatevirtual

Reimplemented from dart::BaseWriteStream.

Definition at line 686 of file datastream.h.

                                    {
    return flushed_size_ + BaseWriteStream::Position();
  }

◆ Realloc()

void dart::StreamingWriteStream::Realloc ( intptr_t new_size )

privatevirtual

Implements dart::BaseWriteStream.

Definition at line 40 of file datastream.cc.

                                                    {

  // Check whether resetting the internal buffer by flushing gave enough space.

    return;
  }
  const intptr_t new_capacity = Utils::RoundUp(new_size, 64 * KB);
  buffer_ = reinterpret_cast<uint8_t*>(realloc(buffer_, new_capacity));
  capacity_ = buffer_ != nullptr ? new_capacity : 0;
  current_ = buffer_;  // Flushing reset the internal buffer offset to 0.
}

◆ SetPosition()

virtual void dart::StreamingWriteStream::SetPosition ( intptr_t value )

inlineprivatevirtual

Reimplemented from dart::BaseWriteStream.

Definition at line 690 of file datastream.h.

                                           {
    // Make sure we're not trying to set the position to already-flushed data.
    ASSERT(value >= flushed_size_);
    BaseWriteStream::SetPosition(value - flushed_size_);
  }
