Detailed Description

Archive for tagging unreachable objects in a non recursive manner.

Constructor & Destructor Documentation

◆ FCollectorTagUsedNonRecursive()

FCollectorTagUsedNonRecursive::FCollectorTagUsedNonRecursive ( )

inline

Default constructor.

Member Function Documentation

◆ IsIgnoringArchetypeRef()

virtual bool FCollectorTagUsedNonRecursive::IsIgnoringArchetypeRef ( ) const

inlineoverridevirtual

If true archetype references should not be added to this collector.

Implements FReferenceCollector.

◆ IsIgnoringTransient()

virtual bool FCollectorTagUsedNonRecursive::IsIgnoringTransient ( ) const

inlineoverridevirtual

If true transient objects should not be added to this collector.

Implements FReferenceCollector.

◆ IsUnreachable()

FORCEINLINE bool FCollectorTagUsedNonRecursive::IsUnreachable ( const UObject * Object ) const

inline

◆ PerformReachabilityAnalysis()

void FCollectorTagUsedNonRecursive::PerformReachabilityAnalysis	(	EObjectFlags	KeepFlags,
		EInternalObjectFlags	InternalKeepFlags,
		EObjectFlags	SearchFlags = `RF_NoFlags`,
		FReferencerInformationList *	FoundReferences = `NULL`
	)

inline

Performs reachability analysis. This information is later used by e.g. IncrementalPurgeGarbage or IsReferenced. The algorithm is a simple mark and sweep where all objects are marked as unreachable. The root set passed in is considered referenced and also objects that have any of the KeepFlags but none of the IgnoreFlags. RF_PendingKill is implicitly part of IgnoreFlags and no object in the root set can have this flag set.

Parameters

KeepFlags	Objects with these flags will be kept regardless of being referenced or not (see line below)
SearchFlags	If set, ignore objects with these flags for initial set, and stop recursion when found
FoundReferences	If non-NULL, fill in with all objects that point to an object with SearchFlags set
