bool DQMBasicNet::removeLocalExcept

(

const std::set< std::string > &

known

)

Delete all local objects not in known. Returns true if something was removed. The caller must call sendLocalChanges() later to push out the changes.

Definition at line 1479 of file DQMNet.cc.

void DQMBasicNet::reserveLocalSpace

(

uint32_t

size

)

Give a hint of how much capacity to allocate for local objects.

void DQMBasicNet::updateLocalObject

(

Object &

o

)

Update the network cache for an object. The caller must call sendLocalChanges() later to push out the changes.
