## PivotCache class


Represents the memory cache for some [PivotTable](../pivottable/) reports.

```cpp
class PivotCache
```

## Methods

| Method | Description |
| --- | --- |
| virtual [Dispose()](./dispose/) | Release all resource. |
| [GetMissingItemsLimit()](./getmissingitemslimit/) | Gets and sets the number of unused items to allow before discarding unused items. This value MUST be greater than -2 and less than 1048577. [PivotCacheMissingItemsLimitConst](../pivotcachemissingitemslimitconst/);. |
| [GetPivotTables()](./getpivottables/) | Gets all pivot tables with this pivot cache. |
| virtual [GetSourceType()](./getsourcetype/) | Gets the [PivotTableSourceType](../pivottablesourcetype/). |
| [IsNull()](./isnull/) const | Checks whether the implementation object is nullptr. |
| explicit [operator bool()](./operator_bool/) const | operator bool() |
| [operator=(const PivotCache\& src)](./operator_asm/) | operator= |
| [PivotCache(PivotCache_Impl* impl)](./pivotcache/) | Constructs from an implementation object. |
| [PivotCache(const PivotCache\& src)](./pivotcache/) | Copy constructor. |
| [Refresh(const PivotTableRefreshOption\& option)](./refresh/) | Refreshes data from the data source and calculates data for the view of all pivottables which data source is this pivot cache. |
| [Refresh()](./refresh/) | Refreshes data from the data source and calculates data for the view of all pivottables which data source is this pivot cache. |
| [SetMissingItemsLimit(int32_t value)](./setmissingitemslimit/) | Gets and sets the number of unused items to allow before discarding unused items. This value MUST be greater than -2 and less than 1048577. [PivotCacheMissingItemsLimitConst](../pivotcachemissingitemslimitconst/);. |
| [~PivotCache()](./~pivotcache/) | Destructor. |
## Fields

| Field | Description |
| --- | --- |
| [_impl](./_impl/) | The implementation object. |
## Remarks


All data will be gathered into this cache,and the pivot table only get data from this cache,not directly access data source. If data source of some [PivotTable](../pivottable/)s are same, they will use a pivot cache.
