newMergeURL

public static java.net.URL newMergeURL(java.net.URL url)

newMergeURL

public static java.net.URL newMergeURL(CompareContributor source,
                                       CompareContributor target,
                                       CompareContributor ancestor)

getFileName

public java.lang.String getFileName(java.net.URL url)

Description copied from class: URLFileSystemHelper

Returns the name of the file contained by the URL, not including any protocol, hostname authentication, directory path, anchor, or query. This simply returns the simple filename. For example, if you pass in an URL whose string representation is:

protocol://host:1010/dir1/dir2/file.ext#anchor?query

the returned value is "file.ext" (without the quotes).

The returned file name should only be used for display purposes and not for opening streams or otherwise trying to locate the resource indicated by the URL.

Overrides:

getFileName in class URLFileSystemHelper

getPlatformPathName

public java.lang.String getPlatformPathName(java.net.URL url)

Description copied from class: URLFileSystemHelper

Returns the platform-dependent String representation of the URL; the returned string should be considered acceptable for users to read. In general, the returned string should omit as many parts of the URL as possible. For the "file" protocol, therefore, the platform pathname should just be the pathname alone (no protocol) using the appropriate file separator character for the current platform. For other protocols, it may be necessary to reformat the URL string into a more human-readable form. That decision is left to each URLFileSystemHelper implementor. The default implementation returns url.toString(). If the URL is null, the empty string is returned.

Overrides:

getPlatformPathName in class URLFileSystemHelper

Returns:

The path portion of the specified URL in platform-dependent notation. This value should only be used for display purposes and not for opening streams or otherwise trying to locate the document.

openInputStream

public java.io.InputStream openInputStream(java.net.URL url)

Overriden to raise an exception on attempting to read the URL.
