// Contents: NDS Pathname Parser
|
||
|
|
|
||
|
|
The Pathname Parser is a key component in ADs providers. It checks for
|
||
|
|
syntactic validity of an ADs pathname that has been passed to this
|
||
|
|
provider. If the syntax is valid, then an OBJECTINFO structure is
|
||
|
|
constructed. This OBJECTINFO structure contains a componentized version
|
||
|
|
of the ADs pathname for this object.
|
||
|
|
|
||
|
|
Note all that is being done is a syntax check. Rather than special-case
|
||
|
|
every single new nuance to pathnames, all path checking must conform to
|
||
|
|
the grammar rules laid out by the parser.
