---

public: virtual bool IsOk() const

---

Tests if the stream is valid.

virtual bool Geo::IGeoStream::IsOk

---

public: bool IsOk() const

---

Tests if the stream is valid.

bool Geo::GeoMemoryStream::Open

---

public: bool Open
(
    size_t startSize
)

---

free current memory, if any, and start new block

bool Geo::GeoMemoryStream::Open

---

public: bool Open
(
    char * data,
    size_t startSize
)

---

free current memory, if any, and open existing block

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

---

public: size_t Read
(
    void * pData,
    size_t size,
    size_t count
)

---

Read data (prototype matches fread). Prefer to use the templated Read methods.

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.

virtual size_t Geo::GeoMemoryStream::Read

---

public: virtual size_t Read
(
    void * pData,
    size_t size,
    size_t count
)

---

Read data (prototype matches fread). Prefer to use the templated Read methods.

bool Geo::IGeoInputStream::Read

---

public: bool Read
(
    T(&) a
)

---

Read a fixed size array.

bool Geo::IGeoInputStream::ReadImpl

---

public: bool ReadImpl
(
    T & object,
    GeoStd::TrueType
)

---

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>).

bool Geo::IGeoInputStream::ReadImpl

---

public: bool ReadImpl
(
    T & object,
    GeoStd::FalseType
)

---

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 Geo::GeoArray<char> Geo::IGeoInputStream::ReadToEnd

---

public: virtual Geo::GeoArray< char > ReadToEnd()

---

Reads the stream to its end and returns the data as a char array.

virtual bool Geo::GeoMemoryStream::SetPosition

---

public: virtual bool SetPosition
(
    u64 pos
)

---

Set the position of the read/write pointer within the stream (prototype matches fseek)

virtual bool Geo::IGeoStream::SetPosition

---

public: bool SetPosition
(
    u64 pos
)

---

Set the position of the read/write pointer within the stream (prototype matches fseek)

virtual bool Geo::IGeoInputStream::SetPosition

---

public: bool SetPosition
(
    Geo::u64 pos
)

---

Set the position of the read/write pointer within the stream (prototype matches fseek)

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.

bool Geo::IGeoStream::Write

---

public: bool Write
(
    const T(&) a
)

---

Write a fixed size array.

virtual size_t Geo::IGeoStream::Write

---

public: size_t Write
(
    const void * pData,
    size_t size,
    size_t count
)

---

Write data (prototype matches fwrite). Prefer to use the templated Write methods.

GEO_FORCE_INLINE bool Geo::IGeoStream::Write

---

public: GEO_FORCE_INLINE bool Write
(
    const T & object
)

---

Write a single object, returning true on success.

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

bool Geo::IGeoStream::Write

---

public: bool Write
(
    TIter begin,
    TIter end
)

---

Write a collection of objects, in range [begin, end) as STL-style classes support.

Objects have same requirements single object Write (see IsBlittable<T>).

virtual size_t Geo::GeoMemoryStream::Write

---

public: virtual size_t Write
(
    const void * pData,
    size_t size,
    size_t count
)

---

Write data (prototype matches fwrite). Prefer to use the templated Write methods.

EStreamMode

---

public: enum EStreamMode
{
    esmWrite,
    esmRead
}

---

An IGeoStream is open in either esmRead or esmWrite mode.
