Static Public Member Functions
static void *	operator new (size_t size)

	accompanying placement operator "new"

static void	operator delete (void *p)
	new operator "delete", to go with the new version of operator new.

static void *	operator new (size_t size, SnapshotState *&o)
	placement "new", needed for stl.

Static Public Attributes

	The name of this class.

static const uint32_t	magic_check_number
	a "magic" number, hashed out of the class definition, that will be used to check consistency of the sent objects across the dueca nodes.

Detailed Description

Enum event type for keeping snapshot info.

Member Enumeration Documentation

Enum type for the different snapshot states and commands.

Enumerator
SnapClear	clear memory used for snapshot
SnapPrepared	prepared module for taking snapshot
SnapNow	take the snapshot at the indicated time
SnapTaken	confirm the snapshot has been taken
SnapSendNotApplicable	say this module does not send a snapshot
SnapSent	confirm snapshot has been sent off
SnapLoaded	confirm snapshot data has been re-loaded
SnapNotFilled	complain no data available
TooLateForSnap	command came too late

static void * dueca::SnapshotState::operator new ( size_t size )

static

new operator "new", which places objects not on a heap, but in one of the memory arenas.

This to speed up memory management.

void dueca::SnapshotState::packDataDiff	(	::dueca::AmorphStore &	s,
		const SnapshotState &	ref ) const

packs the SnapshotState into amorphous storage.

only differences with a previous object are packed.
