IsValid Method

Summary

Indicates if Top and Right are valid combinations for plane.

Syntax

C++/CLI

public bool IsValid( 
   Plane plane 
)

public: 
bool IsValid(  
   Plane plane 
)

Parameters

plane
The specified plane that is being verified as valid combination with Top and Right

Return Value

true if plane is consistent with the combination of Top and Right
