TScriptMap

Untyped map type for accessing [TMap](API\Runtime\Core\Containers\TMap) data, like [FScriptArray](API\Runtime\Core\Containers\FScriptArray) for [TArray](API\Runtime\Core\Containers\TArray).

Syntax

template<typename AllocatorType, typename InDerivedType>  
class TScriptMap

Remarks

Untyped map type for accessing TMap data, like FScriptArray for TArray. Must have the same memory representation as a TMap.

Constructors

  Type Name Description
Public function    
Public function  

TScriptMap ( const TScriptMap&
)

 These should really be private, because they shouldn't be called, but there's a bunch of code that needs to be fixed first.

Functions

  Type Name Description
Public function void

Add ( const void* Key,
const void* Value,
const FScriptMapLayout& Layout,
TFunctionRef< uint32(const void*)> GetKeyHash,
