Method Detail

encodePath

public static String encodePath(String path)

Constructs an encoded version of the specified path string suitable for use in the construction of a URL. A platform-dependent File.separatorChar will be used.

Parameters:

path - the path to escape

Returns:

the path encoded version

decodePath(String)

encodePath

public static String encodePath(String path,
                                boolean flag)

Constructs an encoded version of the specified path string suitable for use in the construction of a URL. A path separator is replaced by a forward slash. The string is UTF8 encoded. The % escape sequence is used for characters that are above 0x7F or those defined in RFC2396 as reserved or excluded in the path component of a URL.

Parameters:

path - the path to escape

flag - indicates whether path uses platform dependent File.separatorChar or not. True indicates path uses platform dependent File.separatorChar

Returns:

the path encoded version

decodePath(String)

decodePath

public static String decodePath(String path)

Returns a new String constructed from the specified String by replacing the URL escape sequences and UTF8 encoding with the characters they represent. The resulting String will be a valid fileName.

Parameters:

path - the path to get from its escaped value

Returns:

the resulting String
