Syntax

Objective-C

C++/CLI

Python

public static bool KernelExpired { get; }

+ (BOOL)kernelExpired

public static boolean getKernelExpired();

public: 
static property bool KernelExpired { 
   bool get(); 
}

KernelExpired # get  (RasterSupport)

Property Value

true if the LEADTOOLS kernel has expired; false, otherwise.

Example

Java

using Leadtools; 
 
 
public void LeadtoolsKernelExample() 
{ 
	// show current kernel 
	switch (RasterSupport.KernelType) 
	{ 
		case RasterKernelType.Release: 
			Console.WriteLine("Release kernel"); 
			break; 
 
		case RasterKernelType.Evaluation: 
			Console.WriteLine("Evaluation kernel"); 
			// show if the kernel has expired 
			if (RasterSupport.KernelExpired) 
				Console.WriteLine("Evaluation kernel has expired"); 
			else 
				Console.WriteLine("Evaluation kernel has not expired yet"); 
			break; 
	}
