Method Details

create

public static URI create(String uri)
                  throws URISyntaxException

This method provides an alternative to the use of java.net.URI's single argument constructor and 'create' method. The drawbacks of the java.net.URI's single argument constructor and 'create' method are:

• They do not provide quoting in the path section for any character not in the unreserved, punct, escaped, or other categories, and not equal to the slash character ('/') or the commercial-at character ('@').
• They do not provide quoting for any illegal characters found in the query and fragment sections.

On the other hand, java.net.URI's seven argument constructor provides these quoting capabilities. In order to take advantage of this constructor, this method parses the given string into the arguments needed thereby allowing for instantiating a java.net.URI with the quoting of all illegal characters.

Parameters:

uri - String representing a URI.

Returns:

Instance of java.net.URI

Throws:

URISyntaxException - Thrown on parsing failures
