Detailed Description

CPP-API: Class to handle file I/O for C++.

Derive an own implementation from this interface to provide custom IO handling to the Importer. If you implement this interface, be sure to also provide an implementation for IOSystem that creates instances of your custom IO class.

Constructor & Destructor Documentation

IOStream()

Assimp::IOStream::IOStream ( void  )

inlineprotected

Constructor protected, use IOSystem::Open() to create an instance.

class IOStream

~IOStream()

Assimp::IOStream::~IOStream ( )

inlinevirtual

Destructor.

Deleting the object closes the underlying file, alternatively you may use IOSystem::Close() to release the file.

Member Function Documentation

FileSize()

virtual size_t Assimp::IOStream::FileSize ( ) const

pure virtual

Returns filesize Returns the filesize.

Read()

virtual size_t Assimp::IOStream::Read ( void *  pvBuffer, size_t  pSize, size_t  pCount  )

pure virtual

Read from the file.

See fread() for more details This fails for write-only files

Seek()

virtual aiReturn Assimp::IOStream::Seek ( size_t  pOffset, aiOrigin  pOrigin  )

pure virtual

Set the read/write cursor of the file.

Note that the offset is negative for aiOrigin_END. See fseek() for more details

Tell()

virtual size_t Assimp::IOStream::Tell ( ) const

pure virtual

Get the current position of the read/write cursor.

See ftell() for more details

Write()

virtual size_t Assimp::IOStream::Write ( const void *  pvBuffer, size_t  pSize, size_t  pCount  )

pure virtual

Write to the file.

See fwrite() for more details This fails for read-only files
