Abstract
Create circular arc centered at x, y with given radius. The start angle and sweep angle are measured in degrees. East is 0°, north 90°, west is 180°, and south is 270°. Positive sweeps are counterclockwise and negative sweeps are clockwise.
Intersect the current clipping shape with this path. This call terminates the current pathing operation.
Close the path by add a line from current point back to starting point.
Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object:
this < that => <0
this == that => 0
this > that => >0
This method may also be accessed via the <
<=
<=>
>=
and >
shortcut operators. If not overridden the default
implementation compares the toStr
representations. Also see docLang.
Examples:
3.compare(8) => -1
8.compare(3) => 1
8.compare(8) => 0
3 <=> 8 => -1 // shortcut for 3.compare(8)
Add a Bézier curve to the path. The cp1 and cp2 parameters specify the first and second control points; x and y specify the end point.
Stroke the the current path using current stroke and paint. This call terminates the current pathing operation.
Compare this object to the specified for equality. This
method may be accessed via the == and != shortcut operators.
If not overridden the default implementation compares for
reference equality using the === operator. If this method
is overridden, then hash() must also be overridden such that
any two objects which return true for equals() must return
the same value for hash(). This method must accept null
and
return false.
Fill the current path with current paint. This call terminates the current pathing operation.
Return a unique hashcode for this object. If a class overrides hash() then it must ensure if equals() returns true for any two objects then they have same hash code.
Add a line to the path from current point to given point.
Move the current point without creating a line.
Add a quadratic Bézier curve to the path. The cpx and cpy specify the control point; the x and y specify the end point.
Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:
Return a string representation of this object.
Trap a dynamic call for handling. Dynamic calls are invoked with the -> shortcut operator:
a->x a.trap("x", null)
a->x() a.trap("x", null)
a->x = b a.trap("x", [b])
a->x(b) a.trap("x", [b])
a->x(b, c) a.trap("x", [b, c])
The default implementation provided by Obj attempts to use reflection. If name maps to a method, it is invoked with the specified arguments. If name maps to a field and args.size is zero, get the field. If name maps to a field and args.size is one, set the field and return args[0]. Otherwise throw UnknownSlotErr.
This method called whenever an it-block is applied to an
object. The default implementation calls the function with this
,
and then returns this
.
Static
echoWrite x.toStr
to standard output followed by newline. If x
is null then print "null". If no argument is provided then
print an empty line.
Optional
x: JsObj
GraphicsPath is used to path complex shapes for stroking, filling, and clipping.
