Subject [jira] [Updated] (CODEC-220) Possible more OO-like approach to DigestUtils
Date Tue, 17 May 2016 09:55:13 GMT

     [ https://issues.apache.org/jira/browse/CODEC-220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sebb updated CODEC-220:
-----------------------
    Attachment: MessageDigestHelper.java

Updated to use static import for constants and renamed getInstance to 'with'.

This makes the code simpler:

byte[] hash = MessageDigestHelper.with(algo).digest(new File("pom.xml"));

> DigestUtils is starting to get a bit unwieldy with so many similar static methods.
> One approach would be to use a Fluent approach (method chaining).
> e.g. DigestUtils.MDA("My-Digest").digestHex(File f);
> There would only need to be digest,digestHex and update instance methods for the different
input types, currently byte, ByteBuffer, InputStream, File.
> Whereas at present these are repeated for each digest type.
