C++ (Cpp) compressedSize Examples

Example #1

File: Compression.cpp Project: KnightSwarm/WebKitTi

bool GenericCompressedData::decompress(uint8_t* destination, size_t bufferSize, size_t* decompressedByteCount)
{
    if (decompressedByteCount)
        *decompressedByteCount = 0;
    z_stream stream;
    memset(&stream, 0, sizeof(stream));
    stream.zalloc = zAlloc;
    stream.zfree = zFree;
    stream.data_type = Z_BINARY;
    stream.opaque = Z_NULL;
    stream.next_out = destination;
    stream.avail_out = bufferSize;
    stream.next_in = m_data;
    stream.avail_in = compressedSize();
    if (inflateInit(&stream) != Z_OK) {
        ASSERT_NOT_REACHED();
        return false;
    }

    int inflateResult = inflate(&stream, Z_FINISH);
    inflateEnd(&stream);

    ASSERT(stream.total_out <= bufferSize);
    if (decompressedByteCount)
        *decompressedByteCount = stream.total_out;

    if (inflateResult != Z_STREAM_END) {
        ASSERT_NOT_REACHED();
        return false;
    }

    return true;
}

Example #2

File: CartesianIndexMapper.hpp Project: GitPaean/opm-grid

 int cartesianIndex( const int compressedElementIndex ) const
 {
     assert(  compressedElementIndex >= 0 && compressedElementIndex < compressedSize() );
     return grid_.globalCell()[ compressedElementIndex ];
 }
