org.codehaus.mojo.versions.rewriting.ModifiedPomXMLEventReader

All Implemented Interfaces:

Iterator, javax.xml.stream.XMLEventReader

public class ModifiedPomXMLEventReader
extends Object
implements javax.xml.stream.XMLEventReader

Represents the modified pom file. Note: implementations of the StAX API (JSR-173) are not good round-trip rewriting while keeping all unchanged bytes in the file as is. For example, the StAX API specifies that CR characters will be stripped. Current implementations do not keep " and ' characters consistent.
