Method Detail

canonicalizeWrite

public static String canonicalizeWrite(String location)

canonicalizeUriString

public static String canonicalizeUriString(String location)

Removes the "file:" or "file://" prefix from the location, if necessary. Also replaces back slashes with forward slashes.

Parameters:

location - a URI string.

Returns:

a canonical URI string.

resolve

public static String resolve(String baseUri,
                             String relativeUri)

This augments URI.resolve(), by also dealing with file: URIs. If baseURi 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:

baseUri - base URI as a Strng

relativeUri - reletive URI, as a String

Returns:

the resolved URI as a String

resolveFile

public static String resolveFile(String baseDir,
                                 String filepath)
