- Constructor Detail
  - DownloadFilesRequest
```
public DownloadFilesRequest()
```
    Constructs a DownloadFilesRequest object with default parameters.
  - DownloadFilesRequest
```
public DownloadFilesRequest(List<String> fileNames,
                            List<Long> readOffsets,
                            List<Long> readLengths,
                            Map<String,String> options)
```
    Constructs a DownloadFilesRequest object with the specified parameters.
    Parameters:
    
    fileNames - An array of the file names to download from KiFS. File paths may contain wildcard characters after the KiFS directory delimiter. Accepted wildcard characters are asterisk (*) to represent any string of zero or more characters, and question mark (?) to indicate a single character.
    
    readOffsets - An array of starting byte offsets from which to read each respective file in fileNames. Must either be empty or the same length as fileNames. If empty, files are downloaded in their entirety. If not empty, readLengths must also not be empty.
    
    readLengths - Array of number of bytes to read from each respective file in fileNames. Must either be empty or the same length as fileNames. If empty, files are downloaded in their entirety. If not empty, readOffsets must also not be empty.
    options - Optional parameters.
    
    FILE_ENCODING: Encoding to be applied to the output file data. When using JSON serialization it is recommended to specify this as BASE64. Supported values:
    
    BASE64: Apply base64 encoding to the output file data.
    NONE: Do not apply any encoding to the output file data.
    The default value is NONE.
    The default value is an empty Map.
