Initialization - Model initialization

Before
The following initialization process is implemented in exec.c/init_all:

set all clock to TS_INIT if initialize all instances fails return error if initialize all loadshapes fails return error for each object if initialize object fails return error if object must be named and is not named return error end for

The following initialization process is implemented in object.c/object_init:

if initialize the object fails, then return error


 * Note : The object clock remains set to the initial clock value 0 until the first call to sync, at which time sync uses the object clock value to determine whether any late initialization will take place.

As of
Object creation set the OF_INIT flag.

The following initialization process is implemented in exec.c/init_all:

set the global clock to the start time if initialize all instances fails, then return error if initialize all loadshapes fails, then return error if initialize all objects fails, then return error return ok

The process to initialize all objects is implemented in object.c/object_initall:

when initialization sequence is creation for each object if initialize object fails, then return error or when initialization sequence is deferred or auto add all objects to initialization list do until initialization list empty for each object in initialization list if initialize object fails, then return error else if initialize object ok, then remove object from initialization list end for end do or when initialization sequence is topdown or bottom up  add all objects to initialization list do until initialization list empty for each rank in initialization sequence for each object in initialization list if initialize object fails, then return error else if initialize object ok, then remove object from initialization list end for end for end do end when

The process to initialize an object is implemented in object.c/object_init:

lock the object set the object clock to start time if the object is not named but the class requires it be named, then return error if initialization sequence is creation or auto, then if the object's parent clock is not set and the PC_NODEFERRAL flag is not set, then return deferred if any of the object's properties are objects that are not initialized and the property's PF_DEFER is the same as the class's PC_NODEFERRAL flag, then return deferred if initialize the object fails, then return error clear the OF_INIT flag unlock the object return success


 * Note : The object clock value is set to the start time during object initialization. As a result, synchronization functions may no longer implement late initialization.  The requirement for late initialization is preempted by the use of deferred initialization and all objects that employed late initialization prior to  should be upgraded to use deferred initialization instead.
