A string wrapped as an object of type {@link SafeUri}.

This class is package-private and intended for internal use by the {@link com.google.gwt.safehtml} package.

All implementors must implement .equals and .hashCode so that they operate just like String.equals() and String.hashCode().

class SafeUriString implements SafeUri {

 String _uri;

  * Constructs a {@link SafeUriString} from a string. Callers are responsible

  * satisfies the constraints of the contract imposed by the {@link SafeUri}
  * interface.
  *
  * @param uri the string to be wrapped as a {@link SafeUri}
