gnc_g_hash_new_guid_numeric()

GHashTable* gnc_g_hash_new_guid_numeric

(

void

)

Returns a GHashTable<GUID*, gnc_numeric*> with no destructor for the key, but a destructor for the value set.

The returned value must be free'd with g_hash_table_destroy or g_hash_table_unref.

Definition at line 1720 of file gnc-sx-instance-model.c.

    return g_hash_table_new_full (guid_hash_to_guint, guid_g_hash_table_equal,

gnc_sx_all_instantiate_cashflow()

void gnc_sx_all_instantiate_cashflow	(	GList *	all_sxes,
		const GDate *	range_start,
		const GDate *	range_end,
		GHashTable *	map,
		GList **	creation_errors
	)

Instantiates the cash flow of all given SXs (in the given GList<SchedXAction*>) into the GHashTable<GUID*, gnc_numeric*> for the given date range.

Each SX is counted with multiplicity as it has occurrences in the given date range.

The creation_errors list, if non-NULL, receive any errors that occurred during creation, similar as in gnc_sx_instance_model_effect_change().

}

gnc_sx_all_instantiate_cashflow_all()

GHashTable* gnc_sx_all_instantiate_cashflow_all	(	GDate	range_start,
		GDate	range_end
	)

Simplified wrapper around gnc_sx_all_instantiate_cashflow(): Run that function on all SX of the current book for the given date range.

Ignore any potential error messages. Returns a newly allocated GHashTable with the result, which is a GHashTable<GUID*, gnc_numeric*>, identical to what gnc_g_hash_new_guid_numeric() would return. The returned value must be free'd with g_hash_table_destroy.

gnc_sx_get_instances()

GncSxInstanceModel* gnc_sx_get_instances	(	const GDate *	range_end,

	)

Allocates a new SxInstanceModel and fills it with generated instances for all scheduled transactions up to the given range_end date.

The caller must unref the returned object by g_object_unref(G_OBJECT(inst_model)); when no longer in use.

gnc_sx_get_select_instances()

GncSxInstanceModel* gnc_sx_get_select_instances

(

GList *

)

Allocates a new SxInstanceModel and fills it with generated instances for the given scheduled transactions up to now.

If no instance exists for a given scheduled transaction, the next instance is generated.

The caller must unref the returned object by g_object_unref(G_OBJECT(inst_model)); when no longer in use.

gnc_sx_instance_model_change_instance_state()

void gnc_sx_instance_model_change_instance_state	(	GncSxInstanceModel *	model,
		GncSxInstance *	instance,
		GncSxInstanceState	new_state
	)

There is a constraint around a sequence of upcoming instance states.

In short: the last-created state and a list of postponed instances are modeled, but upcoming reminders are not. As such, a reminder can never be before any other (modeled) instance type. For instance, the following sequences are disallowed:

[...] remind <- will be lost/skipped over; must be converted to postponed. to-create <- this will be the last-recorded state. [...]

[...] remind <- same as previous; will be lost/skipped; must be postponed. postponed [...]

remind <- same... ignore [...]

As such, the SinceLastRun model will enforce that there are no previous remind instances at every state change. They will be silently converted to postponed-state transactions.

gnc_sx_instance_model_update_sx_instances()

void gnc_sx_instance_model_update_sx_instances	(	GncSxInstanceModel *	model,
		SchedXaction *	sx
	)

Regenerates and updates the GncSxInstances* for the given SX.

Model consumers are probably going to call this in response to seeing the "update" signal, unless they need to be doing something else like finishing an iteration over an existing GncSxInstances*.

gnc_sx_scrub_split_numerics()

void gnc_sx_scrub_split_numerics	(	gpointer	psplit,
		gpointer	user
	)

Fix up numerics where they've gotten out-of-sync with the formulas.

Ideally this would be done at load time, but it requires gnc_exp_parser to work and neither engine nor the backends can depend on it.
