Syntax
struct FTraitStackBinding
Remarks
To keep the node instance cost as low as possible, data such as pointers to the shared data are not stored per node and are instead fetched on demand. In order to be able to query for interfaces on a trait stack from a trait pointer, a trait stack binding must first be created.
Constructors
| Type | Name | Description | |
|---|---|---|---|
 |
Creates an empty/invalid binding. |
Functions

|---|---|---|---|
  |
bool | GetBaseTrait
(
FTraitBinding& OutBinding |
Returns a trait binding to the base of the stack. Returns true on success, false otherwise. |
  |
FWeakTraitPtr | Returns a trait pointer to the base of the trait stack. | |
  |
bool | GetChildTrait
(
const FTraitBinding& ParentBinding, |
Returns a trait binding to the trait above the specified one (its child). |
  |
bool | GetInterface
(
TTraitBinding< TraitInterface >& OutBinding |
The search begins at the top of the stack. Returns true on success, false otherwise. |
  |
bool | GetInterfaceSuper
(
const FTraitBinding& Binding, |

(
const FTraitBinding& ChildBinding, |
Returns a trait binding to the trait below the specified one (its parent). |
  |
bool | GetTopTrait
(
FTraitBinding& OutBinding |
Returns a trait binding to the top of the stack. Returns true on success, false otherwise. |
  |
bool | GetTrait
(
uint32 TraitIndex, |
Returns a trait binding to the trait at the specified index (relative to the start of the stack). |
  |
bool | IsValid () |
Returns whether or not this binding is valid. |
 |
void | Reset () |
Resets the stack binding to an invalid state. |
 |
void | SnapshotLatentProperties
(
bool bIsFrozen |
