TUniqueObj

This is essentially a reference version of [TUniquePtr](API\Runtime\Core\Templates\TUniquePtr) Useful to force heap allocation of a value, e.g. in a [TMap](API\Runtime\Core\Containers\TMap) to give similar behaviour to [TIndirectArray](API\Runtime\Core\Containers\TIndirectArray)

Constructors

Name Description

Public function

TUniqueObj

(
    const TUniqueObj& other
)

Public function

TUniqueObj

(
    TUniqueObj&& other

(
    Args&&... args
)
