Member Function Documentation

XrdProofGroup * XrdProofGroupMgr::Apply	(	int(*)(const char *, XrdProofGroup *, void *)	f,
		void *	arg
	)

Apply function 'f' to the hash table of groups; 'arg' is passed to 'f' in the last argument.

After applying 'f', the action depends on the return value with the following rule: < 0 - the hash table item is deleted. = 0 - the next hash table item is processed. > 0 - processing stops and the hash table item is returned.

int XrdProofGroupMgr::Config

(

const char *

fn

)

(Re-)configure the group info using the file 'fn'.

Return the number of active groups or -1 in case of error.

Definition at line 325 of file XrdProofGroup.cxx.

XrdOucString XrdProofGroupMgr::Export

(

const char *

grp

)

Return a string describing the group.

Definition at line 122 of file XrdProofGroup.h.

XrdProofGroup * XrdProofGroupMgr::GetGroup

(

const char *

grp

)

Returns the instance of for group 'grp.

Return 0 in the case the group does not exist

Definition at line 264 of file XrdProofGroup.cxx.

XrdProofGroup * XrdProofGroupMgr::GetUserGroup	(	const char *	usr,
		const char *	grp = 0
	)

Returns the instance of the first group to which this user belongs; if grp != 0, return the instance corresponding to group 'grp', if existing and the // user belongs to it.

Return 0 in the case the user does not belong to any group or does not belong to 'grp'.

Definition at line 281 of file XrdProofGroup.cxx.

XrdProofGroup * XrdProofGroupMgr::Next

(

)

Returns the instance of next group in the pseudo-iterator functionality.

To scan over all the groups do the following: ResetIter(); while ((g = Next())) { // ... Process group } Return 0 when there are no more groups

Definition at line 316 of file XrdProofGroup.cxx.

int XrdProofGroupMgr::Num ( )

inline

Definition at line 116 of file XrdProofGroup.h.

int XrdProofGroupMgr::ParseInfoFrom ( const char *  fn )

private

Parse config information from the open file 'fin'.

Can be called recursively following 'include sub-file' lines. Return 0 or -1 in case of error.

Definition at line 391 of file XrdProofGroup.cxx.

void XrdProofGroupMgr::Print

(

const char *

grp

)

Return a string describing the group.

Definition at line 246 of file XrdProofGroup.cxx.

int XrdProofGroupMgr::ReadPriorities

(

)

Read update priorities from the file defined at configuration time.

Return 1 if the file did not change, 0 if the file has been read correctly, or -1 in case of error.

Definition at line 515 of file XrdProofGroup.cxx.

void XrdProofGroupMgr::ResetIter ( )

inline

Definition at line 125 of file XrdProofGroup.h.

int XrdProofGroupMgr::SetEffectiveFractions

(

bool

opri

)

Go through the list of active groups (those having at least a non-idle member) and determine the effective resource fraction on the base of the scheduling option and of priorities or nominal fractions.

Return 0 in case of success, -1 in case of error, 1 if every group has the same priority so that the system scheduler should do the job.
