Class protocol:

 new

 scheme: aSchemeString fromString: aString

parse the hierarchical information.
schemeString is ignored here

Instance protocol:

 authority

return the value of the instance variable 'authority' (automatically generated)

 authority: something

set the value of the instance variable 'authority' (automatically generated)

 baseName

 examples

more examples to be added:
[exBegin]
URI fromString:'file:/phys/exept/home/tm/tmp'
[exEnd]

 fragment

return the value of the instance variable 'fragment' (automatically generated)

 fragment: something

set the value of the instance variable 'fragment' (automatically generated)

 isAbsolute

return the value of the instance variable 'isAbsolute' (automatically generated)

 isDirectory

return the value of the instance variable 'isDirectory' (automatically generated)

 pathSegments

return the value of the instance variable 'pathSegments' (automatically generated)

 pathSegments: something

set the value of the instance variable 'pathSegments' (automatically generated)

 query

return the value of the instance variable 'query' (automatically generated)

 query: something

set the value of the instance variable 'query' (automatically generated)

 host

answer the host part of authority

 password

answer the user part of authority

 port

answer the port part of authority

 user

answer the user part of authority

 = anHierarchicalUri

 hash

 postCopy

 defaultPort

answer the default port for the given scheme.
Concrete subclasses redefine this method

 unEscape

convert escaped characters (such as %20 for ' ') to their native
representation

 fromString: aString

 initialize

 directoryPath

answer the directory path part of the URI

 path

answer the path part of the URI

 printOn: aStream

 printOn: aStream escape: doEscape

print the URI on aStream. If doEscape is set, escape special
characters

 printPathOn: aStream escape: doEscape

print the path part

 publicPrintOn: aStream

print, but omit password information

 / aString

concatenate aString to my path.
Same as #construct:, but simpler to use

 addComponent: aString

concatenate aString to my path

 construct: aString

concatenate aString to my path

 directory

remove the last path component

 removeLastComponent

remove the last component
