DocumentLicense.checkLicenseBuffer Method

Module: DocumentLicense

Definition

This function does two things:

  • First it loads the license from a buffer

  • Then it checks the validity of the license regarding the host it is called on (Windows, Linux, Android …)

Important

Calling one of the license checking function is required to get access to all the license member getters.

Note

The optional parameter is required on Android and must be the JNIEnv* pointer casted as a void*. It can be set as NULL for other devices.
