class Root from IntTools
|
||||
|
||||
---Purpose: The class is to describe the root of
|
||||
-- function of one variable for Edge/Edge
|
||||
-- and Edge/Surface algorithms.
|
||||
|
||||
uses
|
||||
State from TopAbs

is
|

Create
|
||||
returns Root from IntTools ;
|
||||
---Purpose:
|
||||
--- Empty constructor
|
||||
---
|
||||
|
||||
Create(aRoot: Real from Standard;
|
||||
aType: Integer from Standard)
|
||||
returns Root from IntTools ;
|
||||
---Purpose:
|
||||
--- Initializes my by range of parameters
|
||||
--- and type of root
|
||||
---
|
||||
|
||||
SetRoot (me:out; aRoot: Real from Standard);
|
||||
---Purpose:
|
||||
--- Sets the Root's value
|
||||
---
|
||||
|
||||
SetType (me:out; aType: Integer from Standard);
|
||||
---Purpose:
|
||||
--- Sets the Root's Type
|
||||
---
|
||||
|
||||
SetStateBefore (me:out; aState: State from TopAbs);
|
||||
---Purpose:
|
||||
--- Set the value of the state before the root
|
||||
--- (at t=Root-dt)
|
||||
---
|
||||
|
||||
SetStateAfter (me:out; aState: State from TopAbs);
|
||||
---Purpose:
|
||||
--- Set the value of the state after the root
|
||||
--- (at t=Root-dt)
|
||||
---
|
||||
|
||||
SetLayerHeight (me:out; aHeight:Real from Standard);
|
||||
---Purpose:
|
||||
--- Not used in Edge/Edge algorithm
|
||||
---
|
||||
|
||||
SetInterval (me:out; t1, t2, f1, f2:Real from Standard);
|
||||
---Purpose:
|
||||
--- Sets the interval from which the Root was
|
||||
--- found [t1,t2] and the corresponding values
|
||||
--- of the function on the bounds f(t1), f(t2).
|
||||
---
|
||||
|
||||
Root (me)
|
||||
returns Real from Standard;
|
||||
---Purpose:
|
||||
--- Returns the Root value
|
||||
---
|
||||
|
||||
Type (me)
|
||||
returns Integer from Standard;
|
||||
---Purpose:
|
||||
--- Returns the type of the root
|
||||
--- =0 - Simple (was found by bisection method);
|
||||
--- =2 - Smart when f1=0, f2!=0 or vice versa
|
||||
--- (was found by Fibbonacci method);
|
||||
--- =1 - Pure (pure zero for all t [t1,t2] );
|
||||
|
||||
StateBefore(me)
|
||||
returns State from TopAbs;
|
||||
---Purpose:
|
||||
--- Returns the state before the root
|
||||
---
|
||||
|
||||
StateAfter(me)
|
||||
returns State from TopAbs;
|
||||
---Purpose:
|
||||
--- Returns the state after the root
|
||||
---
|
||||
|
||||
LayerHeight (me)
|
||||
returns Real from Standard;
|
||||
---Purpose:
|
||||
--- Not used in Edge/Edge algorithm
|
||||
---
|
||||
|
||||
IsValid (me)
|
||||
returns Boolean from Standard;
|
||||
---Purpose:
|
||||
--- Returns the validity flag for the root,
|
||||
--- True if
|
||||
--- myStateBefore==TopAbs_OUT && myStateAfter==TopAbs_IN or
|
||||
--- myStateBefore==TopAbs_OUT && myStateAfter==TopAbs_ON or
|
||||
--- myStateBefore==TopAbs_ON && myStateAfter==TopAbs_OUT or
|
||||
--- myStateBefore==TopAbs_IN && myStateAfter==TopAbs_OUT .
|
||||
--- For other cases it returns False.

Interval (me; t1:out Real from Standard;
|
||||
t2:out Real from Standard;
|
||||
f1:out Real from Standard;
|
||||
f2:out Real from Standard);
|
||||
---Purpose:
|
||||
--- Returns the values of interval from which the Root was
|
||||
--- found [t1,t2] and the corresponding values
|
||||
--- of the function on the bounds f(t1), f(t2).
