- Method Detail
  - listPrefix
```
java.lang.Iterable<FileInfo> listPrefix(java.lang.String prefix)
```
    Return an iterable of all files under a prefix.
    Hierarchical file systems (e.g. HDFS) may impose additional restrictions like the prefix must fully match a directory whereas key/value object stores may allow for arbitrary prefixes.
    
    Parameters:
    
    prefix - prefix to list
    
    Returns:
    
    iterable of file information
  - deletePrefix
```
void deletePrefix(java.lang.String prefix)
```
    Delete all files under a prefix.
    Hierarchical file systems (e.g. HDFS) may impose additional restrictions like the prefix must fully match a directory whereas key/value object stores may allow for arbitrary prefixes.
    
    Parameters:
    
    prefix - prefix to delete
