      Changes


        <https://github.com/pmd/pmd/blob/pmd_releases/6.1.0/docs/pages/release_notes.md#changes-to-the-node-interface>Changes
        to the Node interface

The method |getXPathNodeName| is added to the |Node| interface, which
removes the use of the |toString| of a node to get its XPath element
name (see #569 <https://github.com/pmd/pmd/issues/569>). A default
implementation is provided in |AbstractNode|, to stay compatible with
existing implementors.

The |toString| method of a Node is not changed for the time being, and
still produces the name of the XPath node. That behaviour may however
change in future major releases, e.g. to produce a more useful message
for debugging.


        <https://github.com/pmd/pmd/blob/pmd_releases/6.1.0/docs/pages/release_notes.md#changes-to-cpd-renderers>Changes
        to CPD renderers

The interface |net.sourceforge.pmd.cpd.Renderer| has been deprecated. A
new interface |net.sourceforge.pmd.cpd.renderer.CPDRenderer| has been
introduced to replace it. The main difference is that the new interface
is meant to render directly to a |java.io.Writer| rather than to a
String. This allows to greatly reduce the memory footprint of CPD, as on
large projects, with many duplications, it was causing
|OutOfMemoryError|s (see #795 <https://github.com/pmd/pmd/issues/795>).

|net.sourceforge.pmd.cpd.FileReporter| has also been deprecated as part
of this change, as it's no longer needed.
