Method Detail

initProtocolHandler

public static void initProtocolHandler()

resolve

public static java.lang.String resolve(java.lang.String baseUrl,
                                       java.lang.String relativeUrl)

This augments URI.resolve(), by also dealing with base file: URIs. If baseURL is not a file: scheme, then URI.resolve is called. Otherwise the last "/" is found in the base, and the ref is appended to it.

For file: baseURLS: only reletive URLS not starting with / are supported. This is apparently different from the behavior of URI.resolve(), so may be trouble, but it allows NcML absolute location to be specified without the file: prefix. Example :

 base:     file://my/guide/collections/designfaq.ncml
 ref:      sub/my.nc
 resolved: file://my/guide/collections/sub/my.nc
 

Parameters:

baseUrl - base URL as a Strng

relativeUrl - reletive URL, as a String

Returns:

the resolved URL as a String
