       CGlue - connector glue


SYNOPSIS

       #include <Unidraw/cglue.h>


DESCRIPTION

  Read (6% of 3K)
     CGlue  defines  a  Read (7% of 3K)
natural  size,  elasticity (its rate of
       stretching and shrinking relative  to  other  CGlue),  and
       deformation  limits  (total  amount  it  can  stretch  and
       shrink) in both the horizontal  and  vertical  dimensions.
       CGlue  can  be interposed between two connected connectors
       to augment their connectivity semantics; it acts like  two
       non-linear  springs, one horizontal and one vertical, con-
       necting the connectors' centers.


PUBLIC OPERATIONS

CGlue( float hnat = 0, float vnat = 0, float hshr = 0, float hstr = 0, float vshr = 0, float vstr = 0, float hshrlim = 0, float hstrlim = 0, float vshrlim = 0, float vstrlim = 0 Read (40% of 3K) ) Read (41% of 3K) CGlue(const Shape&) Instantiate CGlue, providing the requisite parame- ters explicitly or inferring them from a Shape object. If a shape is supplied, then the CGlue adopts the shape's natural size, and it assigns the shape's stretchability and shrinkability values to its corresponding CGlue elasticity members to obtain a proportionately equivalent elasticity. It aRead (57% of 3K) lso assigns the shape's stretchability and shrink- ability values to its deformation limit members. The parameters are described below: hnat, vnat: horizontal and vertical natural sizes, screen units hshr, vshr: horizontal and vertical shrinking rate, constant units hstr, vstr: horizontal and vertical stretching rate, constant units Read (73% of 3K) hshrlim, vshrlim: horizontal and vertical shrink limit, screen units hstrlim, vstrlim: horizontal and vertical stretch limit, screen units Create a copy of this CGlue instance. void Rigid() Set all elasticity and deformation limits equal to zero. void Interpose(const CGlue* glue) Change this instance's attributeRead (89% of 3K) s to reflect the series combination of this and glue.
