|---|---|
| ~GeoBufferedFileStream() | close current file, if any |
| ~IGeoInputStream() | Deleting a stream should behave like a close operation. |

| GeoBufferedFileStream() | create with no attached file |

| GetPosition() | Return the position of the read/write pointer within the stream (prototype matches ftell) |
| GetPosition() | Return the position of the read/write pointer within the stream (prototype matches ftell) |
| IsEof() | Is the read pointer at the end of the file (as with feof, only returns true if you have read past end) |
| IsEof() | Is the read/write pointer at the end of the file (as with feof, only returns true if you have read past end) |

| ReadImpl(T &, GeoStd::TrueType) | Read a single object, returning true on success. |
| ReadImpl(T &, GeoStd::FalseType) | Read a single object, returning true on success. |
| ReadToEnd() | Reads the stream to its end and returns the data as a char array. |
| SetPosition(Geo::u64) | Set the position of the read/write pointer within the stream (prototype matches fseek) |
| SetPosition(u64) | Set the position of the read/write pointer within the stream (prototype matches fseek) |
| SetPosition(u64) | Set the position of the read/write pointer within the stream (prototype matches fseek) |
| Write(const T(&)) | Write a fixed size array. |
| Write(TIter, TIter) | Write a collection of objects, in range [begin, end) as STL-style classes support. |
| Write(const void *, size_t, size_t) | Write data (prototype matches fwrite). Prefer to use the templated Write methods. |
| Write(const T &) | Write a single object, returning true on success. |
| Write(const void *, size_t, size_t) | Write data (prototype matches fwrite). Prefer to use the templated Write methods. |

Read a collection of objects, returning true on success.
Object must be considered blittable (see IsBlittable<T>). Note that the storage must have been pre-allocated as it will write directly to the iterators provided. Given that we do not have the STL-style 'back-inserter' classes, for GeoArrays you should use the ReadArray helper function.
