Constructors

  Type Name Description
Public function   Default constructor, will be null
Public function  

TPersistentObjectPtr ( const TObjectID& InObjectID
)

 Construct from a unique object identifier

Functions

  Type Name Description
Public function Const UObject *

Get ()

 Dereference the pointer, which may cause it to become valid again.
Public function Const UObject *

Get ( bool bEvenIfPendingKill
)

 Dereference the lazy pointer, which may cause it to become valid again.
Public function TObjectID & Non-const version of the above
Public function Const const TObjectID & Gets the unique object identifier associated with this lazy pointer.
Public function Const bool

IsNull ()

 Test if this can never point to a live UObject
Public function Const bool Test if this does not point to a live UObject, but may in the future
Public function Const bool

IsStale ()

 Slightly different than !IsValid(), returns true if this used to point to a UObject, but doesn't any more and has not been assigned or reset in the mean time.
Public function Const bool

IsValid ()

 Test if this points to a live UObject
Public function void

Reset ()

 Reset the lazy pointer back to the null state
Public function void Resets the weak ptr only, call this when ObjectId may change

Operators

  Type Name Description
Public function Const UObject & Dereference the pointer
Public function void

operator= ( const TObjectID& InObjectID
)

 Copy from a unique object identifier
Public function void

operator= ( const UObject* Object
)

 Copy from an object pointer
Public function void

operator= ( const FWeakObjectPtr& Other
)

 Copy from an existing weak pointer, reserve IDs if required
Public function Const UObject * Dereference the pointer
