Class PooledXmlParser

java.lang.Object

io.inbot.xmltools.PooledXmlParser

public class PooledXmlParser
extends Object

Helper class for parsing xml documents in a way that reuses document builders. Uses a configurable cache for document builders. DocumentBuilder is NOT thread safe and creating them is somewhat expensive. So this helper class puts them in a nice guava class and uses the thread id as the key. So each thread gets its own DocumentBuilder.
