Updates the file cache of this work item so the ID is at least as large as the input ID

void PDG_WorkItem::updateOutputFile	(	int	index,
		const UT_StringHolder &	path,
		const UT_StringHolder &	tag,
		PDG_File::Hash	hash_code,
		bool	owner
	)

Replaces the output file at the given index, if that index is valid.

bool PDG_WorkItem::upgradeExpectedOutputFiles	(	bool	check_disk,
		bool	clear
	)

protected

Upgrades expected outputs to runtime outputs for this work item.

bool PDG_WorkItem::validateOutputFiles ( )

Checks if the work items output files are valid, e.g. they exist.

void PDG_WorkItem::varReplace	(	const char *	input,
		UT_WorkBuffer &	output
	)		const

Replaces env vars in the target string with respect to the environment and properties of this work item. If py_replace is true, replaces the env vars with a valid python token instead of

void PDG_WorkItem::visualDependencies	(	PDG_WorkItemSet &	deps,
		bool	expand,
		PDG_Scheduler *	filter
	)		const

Returns a copy of the "visual" dependencies, e.g. the ones the user would see if they used TOPs or wanted to print out the DAG itself. This strips out any intenal items/dependencies used by TOPs

void PDG_WorkItem::visualDependents	(	PDG_WorkItemSet &	deps,
		bool	expand,
		PDG_Scheduler *	filter
	)		const

Inverse of the above.

bool PDG_WorkItem::wasModified ( ) const

inline

Returns the work item's modified flag.
