Contructs an AbstractName object from the given URI. The artifactId for the AbstractName is constructed from the URI path (everything up to the ? character) and is composed of four parts delimited by slashes. The artifactId is the only mandatory part, all slashes are mandatory. The name map for the AbstractName is constructed from key=value pairs. Each key=value pair is delimited by a ',' character and the key is separated from the value by the '=' character. Each key must be unique. At least one key=value pair must be specified in the query string. The URI has the following format: [vendorId]/artifactId/[version]/[type]?key=value[,key=value][,...]

Parameters:

uri - The URI to be used to generate an AbstractName.
