GEO_FORCE_INLINE bool Geo::IGeoInputStream::Read

public: GEO_FORCE_INLINE bool Read
(
T & object
)

Read a single object, returning true on success.

There must either be a ReadObject overload for T, or T be considered blittable (see IsBlittable<T>).

virtual size_t Geo::IGeoInputStream::Read

void * pData,
size_t size,
size_t count

bool Geo::IGeoInputStream::Read

public: bool Read
(
TIter begin,
TIter end
)

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.

void * pData,
size_t size,

void Geo::GeoMemoryStream::SetUsedMemorySize

public: void SetUsedMemorySize
(
size_t newSize
)

Set the current usage of the GeoMemoryStream.

If you want to create a buffer of a known size and use other methids to fill it, call Open(x) with the requested size 'x', fill with data and then if successful call SetUsedMemorySize(x) to tell the GeoMemoryStream that this memory has been written to.

bool Geo::GeoMemoryStream::ShrinkBuffer

public: bool ShrinkBuffer()

Crop the buffer to the current cursor position.
