Method Detail

isDirectory

public static boolean isDirectory(URL resourceURL)
                           throws URISyntaxException

Returns true if the URL passed to it corresponds to a directory. This is slightly tricky due to some quirks of the JarFile API. Only jar:// and file:// URLs are supported.

Parameters:

resourceURL - the URL to check

Returns:

true if resource is a directory

Throws:

URISyntaxException

appendTrailingSlash

public static URL appendTrailingSlash(URL originalURL)

Appends a trailing '/' to a URL object. Does not append a slash if one is already present.

Parameters:

originalURL - The URL to append a slash to

Returns:

a new URL object that ends in a slash

getLastModified

public static long getLastModified(URL resourceURL)

Returns the last modified time for file:// and jar:// URLs. This is slightly tricky for a couple of reasons: 1) calling getConnection on a URLConnection to a file opens an InputStream to that file that must then be closed — though this is not true for URLConnections to jar resources 2) calling getLastModified on JarURLConnections returns the last modified time of the jar file, rather than the file within

Parameters:

resourceURL - the URL to return the last modified time for

Returns:

the last modified time of the resource, expressed as the number of milliseconds since the epoch, or 0 if there was a problem
