Syntax
USTRUCT (BlueprintType )
struct FStateTreeStructRef
Remarks
StateTree struct ref allows to get a reference/pointer to a specified type via property binding. It is useful for referencing larger properties to avoid copies of the data, or to be able to write to a bounds property.
The expected type of the reference should be set in "BaseStruct" meta tag.
Example:
USTRUCT() struct FAwesomeTaskInstanceData {
FStateTreeStructRef Data; };
if (const FAwesomeData* Awesome = InstanceData.Data.GetPtr

const T & | Get () |
Returns const reference to the struct, this getter assumes that all data is valid. |

T & | GetMutable () |
Returns mutable reference to the struct, this getter assumes that all data is valid. |
 |
T * | Returns mutable pointer to the struct, or nullptr if cast is not valid. | |
  |
const T * | GetPtr () |
Returns const pointer to the struct, or nullptr if cast is not valid. |
