# MemoryManagement
|
||
|
|
|
||
|
|
The `Napi::MemoryManagement` class contains functions that give the JavaScript engine
|
||
|
|
an indication of the amount of externally allocated memory that is kept alive by
|
||
|
|
JavaScript objects.
|
||
|
|
|
||
|
|
## Methods
|
||
|
|
|
||
|
|
### AdjustExternalMemory
|
||
|
|
|
||
|
|
The function `AdjustExternalMemory` adjusts the amount of registered external
|
||
|
|
memory used to give the JavaScript engine an indication of the amount of externally
|
||
|
|
allocated memory that is kept alive by JavaScript objects.
|
||
|
|
The JavaScript engine uses this to decide when to perform global garbage collections.
|
||
|
|
Registering externally allocated memory will trigger global garbage collections
|
||
|
|
more often than it would otherwise in an attempt to garbage collect the JavaScript
|
||
|
|
objects that keep the externally allocated memory alive.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static int64_t Napi::MemoryManagement::AdjustExternalMemory(Napi::Env env, int64_t change_in_bytes);
|
||
|
|
```
|
||
|
|
|
||
|
|
- `[in] env`: The environment in which the API is invoked under.
|
||
|
|
- `[in] change_in_bytes`: The change in externally allocated memory that is kept
|
||
|
|
alive by JavaScript objects expressed in bytes.
|
||
|
|
|
||
|
|
Returns the adjusted memory value.
