Member Function Documentation

QSafeBitmapFileReader::QSafeBitmapFileReader()

Constructs the QSafeBitmapFileReader object.

[virtual] QSafeBitmapFileReader::~QSafeBitmapFileReader()

Destroys the QSafeBitmapFileReader object.

[override virtual] const SafeRenderer::QSafeBitmap *QSafeBitmapFileReader::getBitmapByID(const SafeRenderer::quint32 hash) const

Reimplements: QSafeBitmapReader::getBitmapByID(const SafeRenderer::quint32 hash) const.

Returns the pointer to the bitmap data that is identified by hash. The hash value is the hash value of the bitmap file name. Hash can be calculated with SafeRenderer::qsafe_hash function.

[override virtual] void QSafeBitmapFileReader::loadBitmap(const SafeRenderer::QSafeFileInfo &fileInfo, const SafeRenderer::quint32 crcArg)

Loads the given in fileInfo. The checksum of the file needs to match with crcArg.

In case of a failure, one of the following exceptions will be thrown:

ConstantDescription
SafeRenderer::QSafeBitmapReader::TooManyThe number of bitmaps exceeds the MAXIMUM value.
SafeRenderer::QSafeBitmapReader::DataCorruptedThe read data does not pass a checksum.
SafeRenderer::QSafeBitmapBuffer::SizeErrorThe bitmap data is shorter than SafeRenderer::Constraints::BITMAPDATA_HEADER_SIZE.
SafeRenderer::QSafeFile::FileException::FailureToOpenThe file could not be opened for reading.
SafeRenderer::QSafeFile::FileException::SeekErrorSeek failed on the opened file. For example, a filesystem error occurred or file was a pipe.
SafeRenderer::QSafeFile::FileException::ReadErrorThe requested number of bytes could not be read from the opened file.
