| returns the state of the function corresponding to the latest call of any methods associated with the function. This function is called by each of the algorithms described later which defined the function Integer Algorithm::StateNumber(). The algorithm has the responsibility to call this function when it has found a solution (i.e. a root or a minimum) and has to maintain the association between the solution found and this StateNumber. Byu default, this method returns 0 (which means for the algorithm: no state has been saved). It is the responsibility of the programmer to decide if he needs to save the current state of the function and to return an Integer that allows retrieval of the state. More... | |
Detailed Description
This class represents the integrand function for computation of an inner integral. The returned value depends on the value type and the flag IsByPoint.
The type of returned value is the one of the following values:
- GProp_Mass - volume computation.
- GProp_CenterMassX, GProp_CenterMassY, GProp_CenterMassZ - X, Y and Z coordinates of center of mass computation.
- GProp_InertiaXX, GProp_InertiaYY, GProp_InertiaZZ, GProp_InertiaXY, GProp_InertiaXZ, GProp_InertiaYZ
- moments of inertia computation.
If the flag IsByPoint is set to Standard_True, the value is returned for the region of space that is delimited by a surface and a point. Otherwise all computations are performed for the region of space delimited by a surface and a plane.
