public class URIKit

extends Object

Safe: This class provides some conveniences for manipulating E URI-tokens.

A URI-token is an E token with a type-code of either URI or URIStart.

 
     <uri> ::= '<' <identifier>
  ':' <uric>* '>'
     <uriStart> ::= '<' <identifier> ':'

Method Detail



normalize
public static Twine normalize(Twine uriText)

Enabled:  Normalizes an input URI string to the "actual" URI string.
 

 A backslash ('\\') normalizes to a slash ('/'), and a vertical
 bar ('|') normalizes to a colon (':'), leaving only URIC
 characters (according to BNF of opaque URIs (see Appendix A)) and the fragment identifier
 (sharp-sign ('#')).
 

 XXX An open question is whether normalize/1 should also normalize
 '%<hex><hex>' to the encoded character.  Currently this is not
 done.








getProtcol
public static Twine getProtcol(Twine uriText)

Enabled:  All text up to but not including the first colon.








getBody
public static Twine getBody(Twine uriText)

Enabled:  All text after the first colon








isURIC
public static boolean isURIC(char c)

Enabled:  According to BNF of opaque URIs (see Appendix A) these are characters
 that can occur within a URI body:
 
    a-z, A-Z, 0-9, any of ;/?:@&=+$,-_.!~*'()%
 In addition, by special dispensation, we allow '\\', which we
 normalize to '/', and '|', which we normalize to ':', and '#'
 which is the fragment indicator.
 

 FileGetter also does these
 normalizations dynamically.
