PetscObjectDelayedDestroy#

Adds an object to a data structure for later destruction.

Synopsis#

PetscErrorCode PetscObjectDelayedDestroy(PetscObject *obj)

Not Collective

Input Parameter#

obj - object to be destroyed

Notes#

Analogue to PetscObjectDestroy() for use in managed languages.

A PETSc object is given a creation index at initialisation based on the communicator it was created on and the order in which it is created. When this function is passed a PETSc object, a pointer to the object is stashed on a garbage dictionary (PetscHMapObj) which is keyed by its creation index.

Objects stashed on this garbage dictionary can later be destroyed with a call to PetscGarbageCleanup().

This function is intended for use with managed languages such as Python or Julia, which may not destroy objects in a deterministic order.
