class  HPG0Constraint  from  NLPlate  inherits  HGPPConstraint from  NLPlate 
---Purpose: define a PinPoint G0  Constraint  used to load a Non Linear

uses
     XY from gp,
     XYZ from gp
     
is
    Create(UV : XY; Value : XYZ) returns mutable HPG0Constraint;
    -- create a G0 Constraint
    -- 

    SetUVFreeSliding(me: mutable; UVFree : Boolean) 
    is  redefined;
    -- If True, allow the UV value to  be modified during optimization
    --  this  is meaningless (has  no  effect) on   non G0 Constraints
    -- default is False
    -- 
    -- 

    SetIncrementalLoadAllowed(me: mutable; ILA : Boolean) 
    is  redefined;
    -- If True, allow the Constraint to be loaded incrementally during optimization
    -- default is False
    -- 


    UVFreeSliding(me)  returns  Boolean 
    is  redefined;
    -- If True, allow the UV value to be modified during optimization
    -- default is False

    IncrementalLoadAllowed(me)  returns  Boolean 
    is redefined;
    -- If True, allow the Constraint to be loaded incrementally during optimization
    -- default is False

    ActiveOrder(me)  returns  Integer 
    is   redefined; 
    --  returns the constraint active  order, i.e. the maximum between
    --  -- the initial constraint i.e 0 (for G0 Constraints)
