virtual bool Geo::GeoMemoryStream::IsEof

public: virtual bool IsEof() const

Is the read/write pointer at the end of the file (as with feof, only returns true if you have read past end)

virtual bool Geo::IGeoStream::IsEof

virtual bool Geo::IGeoInputStream::IsOk

Tests if the stream is valid.

virtual bool Geo::GeoMemoryStream::IsOk

public: virtual bool IsOk() const

Tests if the stream is valid.

virtual bool Geo::IGeoStream::IsOk

public: bool IsOk() const

Geo::NonCopyable::NonCopyable

public: NonCopyable
(
    NonCopyable &&
)

Defaulted to allow move.

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

NonCopyable& Geo::NonCopyable::operator=

public: NonCopyable & operator=
(
    NonCopyable &&
)

Defaulted to allow move.

bool Geo::IGeoInputStream::Read

public: bool Read
(
    T(&) a
)

Read a fixed size array.

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::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.

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::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::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::IGeoStream::SetPosition

public: bool SetPosition
(
    u64 pos
)

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

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::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.

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>).

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.

bool Geo::IGeoStream::Write

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

Write a fixed size array.

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>).

EStreamMode

public: enum EStreamMode
{
    esmWrite,
    esmRead
}

An IGeoStream is open in either esmRead or esmWrite mode.
