  - invoke
```
long invoke(long data,
            int data_len,
            long out_len,
            int quality)
```
    Compresses a block of data using Zlib compression.
    The returned data will be freed with MemoryUtil.memFree(java.nio.Buffer) so it must be heap allocated with MemoryUtil.memAlloc(int).
    
    Parameters:
    
    data - the data to compress
    
    data_len - the data length, in bytes
    
    out_len - returns the compressed data length, in bytes
    
    quality - the compression quality to use
    
    Returns:
    
    the compressed data
