class Geo::IffWriter

    └>Geo::IGeoStream
        └>Geo::IGeoInputStream

An IffWriter allows you to use an IGeoStream to create Iff format binary files easily.

It is passed an IGeoStream in its constructor and also implements IGeoStream, thus making it like an Adaptor pattern. Although the class uses the terms 'BeginFile' and 'EndFile' the underlying stream can be of any type.

Functions

Enums

Geo::IffWriter::~IffWriter

...

public: ~IffWriter()

...

Note: Does not close the underlying IGeoStream (so you can write multiple Iff files to one IGeoStream)

virtual Geo::IGeoInputStream::~IGeoInputStream

...

public: virtual ~IGeoInputStream()

...

Deleting a stream should behave like a close operation.

virtual Geo::IGeoStream::~IGeoStream

...

public: virtual ~IGeoStream()

...

Deleting a stream should behave like a close operation.

bool Geo::IffWriter::BeginChunk

...

public: bool BeginChunk
(
    u32 type
)

...

Begin a new Iff chunk.

These are used to allow selective loading (and to skip data that is not expected)

bool Geo::IffWriter::BeginFile

...

public: bool BeginFile
(
    u32 fileType,
    s32 fileVersion
)

...

Write the Iff preamble and leave space to go back and fill in block data sizes, etc.

You are encouraged to make the Iff tag public and somewhere that other code can access.

virtual u32 Geo::IGeoStream::BeginType

...

public: virtual u32 BeginType
(
    TypeId type,
    u32 count
)

...

Provide information about the typed data written to the stream.

bool Geo::IffWriter::EndChunk

...

public: bool EndChunk()

...

Close the most recent chunk (note that the position of the stream when this is called determines the size of the chunk, be careful when jumping around inside IffWriter not to leave your current chunk)

bool Geo::IffWriter::EndFile

...

public: bool EndFile()

...

Close all open chunks, going back and filling in the chunk sizes before this point.

Does not close the underlying IGeoStream.

virtual void Geo::IGeoStream::EndType

...

public: virtual bool IsOk() const

...

Wrap the IGeoStream::IsOk function, returning status of the IffWriter also.

bool Geo::IffWriter::IsWriterOk

...

public: bool IsWriterOk() const

...

Return status of the writer.

Deprecated

Prefer to use the IGeoStream::IsOk() method

Geo::NonCopyable::NonCopyable

...

public: NonCopyable
(
    NonCopyable &&
)

...

Defaulted to allow move.

NonCopyable& Geo::NonCopyable::operator=

...

public: NonCopyable & operator=
(
    NonCopyable &&
)

...

bool Geo::IGeoInputStream::Read

...

public: bool Read
(
    T(&) a
)

...

Read a fixed size array.

virtual size_t Geo::IffWriter::Read

...

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

)

...

Wrap the IGeoStream::Read function, making it invalid.

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>).

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>).

bool Geo::IGeoInputStream::ReadImpl

...

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

...

...

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::IffWriter::SetPosition

...

public: virtual bool SetPosition
(
    u64 pos

...

Wrap the IGeoStream::SetPosition function, be careful when jumping around inside IffWriter.

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)

bool Geo::IGeoStream::Write

bool Geo::IGeoStream::Write

...

    TIter begin,
    TIter end

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