Detailed Description

Assimp file system handler backed by SLFileStorage.

Installed on the Assimp importer with SetIOHandler in SLAssimpImporter::load, so that every file Assimp opens is resolved through SLFileStorage rather than the C runtime. Paths are looked up with the IOK_model file kind.

Definition at line 60 of file SLAssimpIOSystem.h.

Member Function Documentation

Close()

void SLAssimpIOSystem::Close ( Assimp::IOStream *  pFile )

override

Closes the stream and deletes the adapter created by Open.

Definition at line 88 of file SLAssimpIOSystem.cpp.

{
    SLAssimpIOStream* stream = dynamic_cast<SLAssimpIOStream*>(pFile);
    SLFileStorage::close(stream->stream());
    delete stream;
}

Exists()

bool SLAssimpIOSystem::Exists ( const char *  pFile ) const

override

Returns true if pFile can be opened through SLFileStorage.

Definition at line 62 of file SLAssimpIOSystem.cpp.

{
    return SLFileStorage::exists(pFile, IOK_model);
}

getOsSeparator()

char SLAssimpIOSystem::getOsSeparator ( ) const

override

Returns the path separator, always '/' for SLProject paths.

Definition at line 67 of file SLAssimpIOSystem.cpp.

{
    return '/';
}

Open()

Assimp::IOStream * SLAssimpIOSystem::Open ( const char *  pFile, const char *  pMode  )

override

Opens pFile through SLFileStorage and wraps it in an SLAssimpIOStream.

Parameters

pFile	Path of the file to open
pMode	Assimp mode string ("rb", "r", "rt", "wb", "w", "wt"). Only the first character is inspected, because an SLIOStream is always binary.

Definition at line 72 of file SLAssimpIOSystem.cpp.

{
    // Assimp requires the modes "wb", "w", "wt", "rb", "r" and "rt".
    // The second character is ignored because SLIOStreams are always binary.
    // Therefor we only need to check the first character to determine
    // whether we are reading or writing.
    SLIOStreamMode streamMode = IOM_read;
    if (pMode[0] == 'r')
        streamMode = IOM_read;
    else if (pMode[0] == 'w')
        streamMode = IOM_write;
 
    SLIOStream* stream = SLFileStorage::open(pFile, IOK_model, streamMode);
    return new SLAssimpIOStream(stream);
}
