  - applyDataFilter
```
BufferVault applyDataFilter(boolean last,
                            BufferVault dataSources)
                     throws IOException
```
    Parameters:
    
    dataSource - can be empty after call
    
    last - if true, you should use flush/close internal needs and return last responses, because applyDataFilter will never be called for the current instance.
    
    Returns:
    
    empty for "ignore" filter/data collector filter null for stop data transfert operation returned BufferVault can be re-used here after, and can be empty after call
    
    Throws:
    
    IOException
  - onCancelTransfert
```
default void onCancelTransfert()
```
  - ensureMinDataSourcesDataLength
```
default int ensureMinDataSourcesDataLength()
```
    Ensure to all applyDataFilter call will contain a total dataSources size equals/more than with this value. Else applyDataFilter with last = true will be called
    
    Returns:
    
    byte count
  - getFilterName
```
default String getFilterName()
