A Point represents an x- and y-coordinate pair in two-dimensional space.
|
|
<p>
|
|
Use the static functions <a href="../symbols/Point.html#.parse" class="linkStatic">Point.parse</a> and <a href="../symbols/Point.html#.stringify" class="linkStatic">Point.stringify</a> to convert to and from
|
|
a standard string representation that is independent of the current locale.
|
|
<p>
|
|
When an instance of this class is the value of a property of a <a href="../symbols/GraphObject.html" class="linkConstructor">GraphObject</a> class or <a href="../symbols/Diagram.html" class="linkConstructor">Diagram</a>
|
|
or <a href="../symbols/CommandHandler.html" class="linkConstructor">CommandHandler</a> or a <a href="../symbols/Tool.html" class="linkConstructor">Tool</a> class, you should treat the object
|
|
as if it were frozen or read-only -- you cannot modify its properties.
|
|
This allows the property to return a value without allocating a new instance.
|
|
If you need to do your own calculations with the value, call <a href="../symbols/Point.html#copy" class="linkMethod">copy</a> to make
|
|
a new instance with the same values that you can modify.
|
|
<p>
|
|
Many methods modify the object's properties and then return a reference to "this" object.
|
|
The only instance method to allocate a new object is the <a href="../symbols/Point.html#copy" class="linkMethod">copy</a> method.
|
|
The static <a href="../symbols/Point.html#.parse" class="linkStatic">Point.parse</a> method also allocates a new object.
|
|
<p>
|
|
The "Debug" implementation of this class is significantly slower than the "Release" implementation,
|
|
mostly due to additional error checking.
|
|
<p>
|
|
You cannot inherit from this class.
