org.waveprotocol.wave.model.document.util.XmlStringBuilder
A safe container for building xml strings This is a Mutable class, it uses a StringBuilder internally for performance This class provides an interface, and some handy constructor methods. The implementation is in {@link XmlStringBuilderDoc}. That class also extends this interface to provide methods to convert nodes to their string representation using a document view. The need for that capability is rarer, and hence the split into two classes, so users don't have to suffer the verbosity of generics if they are just building a string. The static constructors here will return the appropriate type depending on whether a document view is given in the constructor, and so we also gain type safety (it's impossible to call "appendNode" on a builder that was not constructed with a document view.) @author danilatos@google.com (Daniel Danilatos)
