generic class B2x from Bnd (RealType as any)
uses XY from gp,
Ax2d from gp,
Pnt2d from gp,
Trsf2d from gp
is
Create returns B2x from Bnd;
---Purpose: Empty constructor.
---C++: inline
Create (theCenter: XY from gp; theHSize : XY from gp)
returns B2x from Bnd;
---Purpose: Constructor.
---C++: inline
IsVoid (me)
returns Boolean from Standard;
---Purpose: Returns True if the box is void (non-initialized).
---C++: inline
Clear (me:in out);
---Purpose: Reset the box data.
---C++: inline
Add (me:in out; thePnt: XY from gp);
---Purpose: Update the box by a point.
Add (me:in out; thePnt: Pnt2d from gp);
---Purpose: Update the box by a point.
Add (me:in out; theBox: B2x from Bnd);
---Purpose: Update the box by another box.
---C++: inline
CornerMin (me)
returns XY from gp;
---Purpose: Query a box corner: (Center - HSize). You must make sure that
-- the box is NOT VOID (see IsVoid()), otherwise the method returns
-- irrelevant result.
---C++: inline
CornerMax (me)
returns XY from gp;
---Purpose: Query a box corner: (Center + HSize). You must make sure that
-- the box is NOT VOID (see IsVoid()), otherwise the method returns
-- irrelevant result.
---C++: inline
SquareExtent(me)
returns Real from Standard;
---Purpose: Query the square diagonal. If the box is VOID (see method IsVoid())
-- then a very big real value is returned.
---C++: inline
Enlarge (me:in out; theDiff: Real from Standard);
---Purpose: Extend the Box by the absolute value of theDiff.
---C++: inline
Limit (me:in out; theOtherBox: B2x from Bnd)
returns Boolean from Standard;
---Purpose: Limit the Box by the internals of theOtherBox.
-- Returns True if the limitation takes place, otherwise False
-- indicating that the boxes do not intersect.
Transformed (me; theTrsf: Trsf2d from gp)
returns B2x from Bnd;
---Purpose: Transform the bounding box with the given transformation.
-- The resulting box will be larger if theTrsf contains rotation.
IsOut (me; thePnt: XY from gp)
returns Boolean from Standard;
---Purpose: Check the given point for the inclusion in the Box.
-- Returns True if the point is outside.
---C++: inline
IsOut (me; theCenter : XY from gp;
theRadius : Real from Standard;
isCircleHollow: Boolean from Standard = Standard_False)
returns Boolean from Standard;
---Purpose: Check a circle for the intersection with the current box.
-- Returns True if there is no intersection between boxes.
IsOut (me; theOtherBox: B2x from Bnd)
returns Boolean from Standard;
---Purpose: Check the given box for the intersection with the current box.
-- Returns True if there is no intersection between boxes.
---C++: inline
IsOut (me; theOtherBox: B2x from Bnd; theTrsf: Trsf2d from gp)
returns Boolean from Standard;
---Purpose: Check the given box oriented by the given transformation
-- for the intersection with the current box.
-- Returns True if there is no intersection between boxes.
IsOut (me; theLine: Ax2d from gp)
returns Boolean from Standard;
---Purpose: Check the given Line for the intersection with the current box.
-- Returns True if there is no intersection.
IsOut (me; theP0, theP1: XY from gp)
returns Boolean from Standard;
---Purpose: Check the Segment defined by the couple of input points
-- for the intersection with the current box.
-- Returns True if there is no intersection.
IsIn (me; theBox: B2x from Bnd)
returns Boolean from Standard;
---Purpose: Check that the box 'this' is inside the given box 'theBox'. Returns
-- True if 'this' box is fully inside 'theBox'.
---C++: inline
IsIn (me; theBox: B2x from Bnd; theTrsf: Trsf2d from gp)
returns Boolean from Standard;
---Purpose: Check that the box 'this' is inside the given box 'theBox'
-- transformed by 'theTrsf'. Returns True if 'this' box is fully
-- inside the transformed 'theBox'.
SetCenter (me: in out; theCenter: XY from gp);
---Purpose: Set the Center coordinates
---C++: inline
SetHSize (me: in out; theHSize: XY from gp);
---Purpose: Set the HSize (half-diagonal) coordinates.
-- All components of theHSize must be non-negative.
---C++: inline
fields
myCenter : RealType[2] is protected;
myHSize : RealType[2] is protected;
