LicenseManager

The LicenseManager class provides a set of APIs to manage the licensing for the Dynamsoft Capture Vision architecture.

getDeviceUUID

Returns the unique identifier of the device.

static getDeviceUUID(): Promise<string>;

Return Value

A promise which, upon resolution, yields a string corresponding to the device’s UUID.

initLicense

Initializes the license for the application using a license key. This function is overloaded, providing two different usages based on the provided parameters.

static initLicense(license: string, immediately?: boolean): void | Promise<void>;

Parameters

license: The license key to be used for initialization.

immediately: A boolean flag that determines if the function should immediately execute the license initialization or not.

Return Value

void

• When immediately is undefined or false, this signature of initLicense passes the license key to the application for initialization at a later stage. It doesn’t provide immediate feedback and is suitable for scenarios where immediate confirmation of license initialization is not required.

• When immediately is true, this returns a promise that resolves when the operation finishes. It does not provide any value upon resolution. Please note that it may raise up license related exceptions.

Code snippet

Dynamsoft.License.LicenseManager.initLicense("your-license-key", true)
  .then(result => {
    if (result?.message) {
      console.log("License Message:", result.message);
    } else {
      console.log("License initialized successfully");
    }
  })
  .catch(error => {
    console.error("License initialization failed:", error);
  });

setDeviceFriendlyName

Assigns a distinctive name to the device, correlating it with its UUID.

Please be aware that this method must be called before Dynamsoft.CVR.CaptureVisionRouter.createInstance() or Dynamsoft.Core.CoreModule.loadWasm() or Dynamsoft.DCP.CodeParser.createInstance() to take effect.

static setDeviceFriendlyName(name: string): void;

Parameters

name: A string representing the device which is easier to recognize than its UUID.

Return Value

void
