## Member Function Documentation

## ◆ OnOutOfMemory()

virtual void foxit::common::NotifierCallback::OnOutOfMemory | ( |  | ) |
| pure virtual

A callback function used to notify application when Foxit PDF SDK runs out of memory.

When this callback function is triggered, that means Foxit PDF SDK runs out of memory. At this moment, application cannot use any API in Foxit PDF SDK. In this case, application can exit with some warning information, or application is aborted and tried to restart. Here, "restart an application" does not mean to call function Library::Reinitialize but to call function Library::Initialize again to load Foxit PDF SDK again from the beginning.

Returns
  None.

## ◆ Release()

virtual void foxit::common::NotifierCallback::Release | ( |  | ) |
| pure virtual

A callback function used to release current callback object itself.

Returns
  None.
