C++ (Cpp) getIResource Examples

Example #1

File: herffile.cpp Project: bazhenovc/xoreos

Common::SeekableReadStream *HERFFile::getResource(uint32 index) const {
	const IResource &res = getIResource(index);
	if (res.size == 0)
		return new Common::MemoryReadStream(0, 0);

	Common::SeekableReadStream *herf = ResMan.getResource(TypeMan.setFileType(_fileName, kFileTypeNone), kFileTypeHERF);
	if (!herf)
		throw Common::Exception(Common::kOpenError);

	if (!herf->seek(res.offset)) {
		delete herf;
		throw Common::Exception(Common::kSeekError);
	}

	Common::SeekableReadStream *resStream = herf->readStream(res.size);

	if (!resStream || (((uint32) resStream->size()) != res.size)) {
		delete herf;
		delete resStream;
		throw Common::Exception(Common::kReadError);
	}

	delete herf;
	return resStream;
}

Example #2

File: biffile.cpp Project: ImperatorPrime/xoreos

Common::SeekableReadStream *BIFFile::getResource(uint32 index, bool tryNoCopy) const {
	const IResource &res = getIResource(index);

	if (tryNoCopy)
		return new Common::SeekableSubReadStream(_bif.get(), res.offset, res.offset + res.size);

	_bif->seek(res.offset);

	return _bif->readStream(res.size);
}

Example #3
