Constructors

  Type Name Description
Public function    
Public function  

FKeyHandleMap ( const FKeyHandleMap& Other
)

 This struct is not copyable. This must be public or because derived classes are allowed to be copied.

Functions

  Type Name Description
Public function void

Add ( const FKeyHandle& InHandle,
int32 InIndex
)

 TMap functionality
Public function Const TArray< FKeyHandle >::TConstIterator  
Public function void

Empty ( int32 ExpectedNumElements
)

  
Public function void

EnsureAllIndicesHaveHandles ( int32 NumIndices
)

 Ensures that all indices have a valid handle and that there are no handles left to invalid indices.
Public function void

EnsureIndexHasAHandle ( int32 KeyIndex
)

 Ensures a handle exists for the specified Index.
Public function Const const int32 *

Find ( const FKeyHandle& InHandle
)

  
Public function Const const FKeyHandle *

FindKey ( int32 KeyIndex
)

  
Public function Const const TMap< FKeyHandle, int32 > &

GetMap ()

  
Public function void

Initialize ( TArrayView< const FKeyHandle > InKeyHandles
)

 Quickly initializes this map by clearing it and filling with KeyHandles in O(n) time, instead of O(n^2) if Add() was used in a loop.
