Functions

  Type Name Description
Public function void

Append ( TMap< KeyType, ValueType, OtherSetAllocator, KeyFuncs >&& OtherMap
)

 Move all items from another map into our map (if any keys are in both, the value from the other map wins) and empty the other map.
Public function void

Append ( const TMap< KeyType, ValueType, OtherSetAllocator, KeyFuncs >& OtherMap
)

 Add all items from another map to our map (if any keys are in both, the value from the other map wins).
Public function ValueType Find a pair with the specified key, removes it from the map, and returns the value part of the pair.
Public function bool

RemoveAndCopyValue ( KeyInitType Key,
ValueType& OutRemovedValue
)

 Remove the pair with the specified key and copies the value that was removed to the ref parameter
Public function bool

RemoveAndCopyValueByHash ( uint32 KeyHash,
const ComparableKey& Key,
ValueType& OutRemovedValue
)

 See RemoveAndCopyValue() and class documentation section on ByHash() functions
