Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`compress(java.nio.FloatBuffer buffer, java.nio.ByteBuffer compressed)`	compress the buffer into the byte buffer.
`void`	`decompress(java.nio.ByteBuffer compressed, java.nio.FloatBuffer buffer)`	Decompress the byte buffer and restore the buffer from it, again enough space must already be allocated.

    Description copied from interface: ICompressor
    
    compress the buffer into the byte buffer. Attention enough space must already be allocated.
    
    Specified by:
    
    compress in interface ICompressor<java.nio.FloatBuffer>
    
    Parameters:
    
    buffer - the buffer to compress.
    
    compressed - the compressed data
    
    Returns:
    
    true if the compression succeeded.
  - decompress
```
public void decompress(java.nio.ByteBuffer compressed,
                       java.nio.FloatBuffer buffer)
```
    Description copied from interface: ICompressor
    
    Decompress the byte buffer and restore the buffer from it, again enough space must already be allocated.
    
    Specified by:
    
    decompress in interface ICompressor<java.nio.FloatBuffer>
    
    Parameters:
    
    compressed - the compressed data
    
    buffer - the buffer to fill with the uncompressed data.
