Constructor Detail

plotArc

public plotArc(double x,
               double y,
               double r,
               double s,
               double t,
               fundamentals.mouseInfo info)
        throws DesignException,
               UserException

The constructor does initialization. A zero generator vector gives a LeaRuntimeException. A degenerate interval is handled by the warner.

Parameters:

x - the first coordinate of anchor

y - the second coordinate of anchor

r - the radius

s - the lo parameter of the endpoint

t - the hi parameter of the endpoint

Throws:

DesignException - if an error occurs

UserException - if an error occurs

               double y,
               double r,
               double s,
               double t,
               fundamentals.mouseInfo info,
               boolean isRadius)
        throws DesignException,
               UserException

The constructor does initialization. A zero generator vector gives a LeaRuntimeException. A degenerate interval is handled by the warner.

Parameters:

x - the first coordinate of anchor

y - the second coordinate of anchor

r - the radius

s - the lo parameter of the endpoint

t - the hi parameter of the endpoint

Throws:

DesignException - if an error occurs

UserException - if an error occurs
