OSD_Protection Class Reference

This class provides data to manage file protection
Example:These rights are treated in a system dependent manner :
On UNIX you have User,Group and Other rights
On VMS you have Owner,Group,World and System rights
An automatic conversion is done between OSD and UNIX/VMS.

OSD VMS UNIX
User Owner User
Group Group Group
World World Other
System System (combined with Other)

When you use System protection on UNIX you must know that
Other rights and System rights are inclusively "ORed".
So Other with only READ access and System with WRITE access
will produce on UNIX Other with READ and WRITE access.

This choice comes from the fact that ROOT can't be considered
as member of the group nor as user. So it is considered as Other.

Detailed Description

This class provides data to manage file protection
Example:These rights are treated in a system dependent manner :
On UNIX you have User,Group and Other rights
On VMS you have Owner,Group,World and System rights
An automatic conversion is done between OSD and UNIX/VMS.

OSD VMS UNIX
User Owner User
Group Group Group
World World Other
System System (combined with Other)

When you use System protection on UNIX you must know that
Other rights and System rights are inclusively "ORed".
So Other with only READ access and System with WRITE access
will produce on UNIX Other with READ and WRITE access.

This choice comes from the fact that ROOT can't be considered
as member of the group nor as user. So it is considered as Other.

Constructor & Destructor Documentation

OSD_Protection::OSD_Protection

(

)

 Initializes global access rights as follows <br>

User : Read Write
System : Read Write
Group : Read
World : Read

OSD_Protection::OSD_Protection	(	const OSD_SingleProtection	System,
		const OSD_SingleProtection	User,
		const OSD_SingleProtection	Group,
		const OSD_SingleProtection	World
	)

Sets values of fields

Member Function Documentation

void OSD_Protection::Add	(	OSD_SingleProtection &	aProt,
		const OSD_SingleProtection	aRight
	)

Add a right to a single protection.
ex: aProt = RWD
me.Add(aProt,X) -> aProt = RWXD

OSD_SingleProtection OSD_Protection::Group

(

)

const

Gets protection of 'Group'

void OSD_Protection::SetGroup

(

const OSD_SingleProtection

priv

)

Sets protection of 'Group'

void OSD_Protection::SetSystem

(

const OSD_SingleProtection

priv

)

Sets protection of 'System'

void OSD_Protection::SetUser

(

const OSD_SingleProtection

priv

)

Sets protection of 'User'

void OSD_Protection::SetValues	(	const OSD_SingleProtection	System,
		const OSD_SingleProtection	User,
		const OSD_SingleProtection	Group,
		const OSD_SingleProtection	World
	)

Sets values of fields

void OSD_Protection::SetWorld

(

const OSD_SingleProtection

priv

)

Sets protection of 'World'

void OSD_Protection::Sub	(	OSD_SingleProtection &	aProt,
		const OSD_SingleProtection	aRight
	)

ex: aProt = RWD
me.Sub(aProt,RW) -> aProt = D
But me.Sub(aProt,RWX) is also valid and gives same result.

		OSD_SingleProtection &	Group,
		OSD_SingleProtection &	World
	)

Retrieves values of fields

OSD_SingleProtection OSD_Protection::World

(

)
