Parameters:

ch - the character

true if character should be encoded

parseUri

public FileName parseUri(VfsComponentContext context,
                         FileName base,
                         String uri)
                  throws FileSystemException

Parse a URI.

Parameters:

context - The component context.

base - The base FileName.

isUrlBased

protected boolean isUrlBased(FileName base,
                             String fileName)

Guess if the given file name is a URL with host or not.

VFS treats such URLs differently.

A file name is URL-based if the base is a URLFileName or there are only 2 slashes after the scheme. e.g: http://host/path, file:/path/to/file, file:///path/to/file.

Parameters:

base - The file name is relative to this base.

fileName - The file name.

Returns:

true if file name contains two slashes or base was URLFileName.

countSlashes

protected int countSlashes(String fileName)

This method counts the slashes after the scheme.

Parameters:

fileName - The file name.

Returns:

number of slashes
