Use System.arraycopy() to improve performance. Initialize expensive arrays in class static initializers, and create a per instance copy of this array initialized with System.arrarycopy(). Vector is convenient to use, but inefficient. For best performance, use it only when the structure size is ...

Returns the Centroid of the 2 (or 2.5) Dimensional figure. The Centroid is the center of the weighted area. Remarks The Centroid does not always occur inside the Area of the geometry. The Centroid is not the same as the center of the geometry or the Envelope binding the geometry (but it...

IronPython supports indexing of System.Array with a type object to access one-dimensional strongly-typed arrays: >>> System.Array[int] <type 'Array[int]'> IronPython also adds a __new__ method that accepts a IList<T> to initialize the array. This allows using a Python list literal to...
