CommonsDigester (Apache Tika 2.9.1 API)

java.lang.Object
- org.apache.tika.parser.digest.CompositeDigester
- - org.apache.tika.parser.digestutils.CommonsDigester

All Implemented Interfaces:

DigestingParser.Digester
```
public class CommonsDigester
extends CompositeDigester
```
Implementation of DigestingParser.Digester that relies on commons.codec.digest.DigestUtils to calculate digest hashes.
This digester tries to use the regular mark/reset protocol on the InputStream. However, this wraps an internal BoundedInputStream, and if the InputStream is not fully read, then this will reset the stream and spool the InputStream to disk (via TikaInputStream) and then digest the file.

public CommonsDigester(int markLimit,
                       String algorithmString)
```
    Include a string representing the comma-separated algorithms to run: e.g. "md5,sha1". If you want base 32 encoding instead of hexadecimal, add ":32" to the algorithm, e.g. "md5,sha1:32"
    Will throw an IllegalArgumentException if an algorithm isn't supported
    
    Parameters:
    
    markLimit -
    
    algorithmString -

public CommonsDigester(int markLimit,
                       CommonsDigester.DigestAlgorithm... algorithms)
```
    Deprecated.
    use CommonsDigester(int, String)
    
    Parameters:
    
    markLimit - limit for mark/reset; after this limit is hit, the stream is reset and spooled to disk
    
    algorithms - algorithms to run

@Deprecated
public static CommonsDigester.DigestAlgorithm[] parse(String s)
```
    Deprecated.
    use the CommonsDigester(int, String) instead
    
    This returns digest algorithms only. It does not understand the encoding syntax, e.g. "MD5:32" (base 32 encoding of MD5). To parse those, see CommonsDigester(int, String).
    
    Parameters:
    
    s - comma-delimited (no space) list of algorithms to use: md5,sha256.
    
    Returns:
