getQueryMap

public static Map<String,String> getQueryMap(String query)

Splits the URL query string into a map of parameter name and value pairs.

Parameters:

query - the query string, e.g. foo=bar&q=z, may be null - in this case an empty map is returned.

Returns:

the map which maps parameter name to the parameter value

toLocalFile

public static String toLocalFile(String fileUri)

Converts given file object to a local filesystem file with absolute path. Returns null if the file is not located on a local filesystem.

Parameters:

fileUri - the file to convert, in the URI format. WARNING: if given string is a local filesystem-dependent path then the function may return null.

Returns:

filesystem-dependent location of the file. null if given URL is not a local-filesystem URL.

Throws:

IllegalArgumentException - if the file is not located on the local filesystem.

toUri

public static String toUri(String fileUri)

Converts given path to an URI if OS-dependent path is given. Simply returns the string if an URI is given.

Parameters:

fileUri - the file name to convert, may be in the URI format or it may be a local filesystem reference.

Returns:

URI, never null

normalizeSlashes

public static String normalizeSlashes(String fileName)
