PolygonDbl2s

Method for creating new data elements from 2 Doubles In the case of ArrDbl2s this will be thee type of the elements of the sequence.

Performs a side effecting function on each element of this sequence in order.

Performs a side effecting function on each element of this sequence in order.

Specialised map to an immutable ArrBase of B.

Foreachs over the tail of the data sequence.

foldLeft over the tail of the data sequence.

Just a handy short cut to give the length of this collection as a string.

The number of product elements in this collection. For example in a [[PolygonImp], this is the number of Pt2s in the Polygon

The element String allows the composition of toString for the whole collection. The syntax of the output will be reworked.

Map this collection of data elements to PolygonLike class of type BB.

String specifying the type of this object.

Sets / mutates elements in the Arr. This method should rarely be needed by end users, but is used by the initialisation and factory methods.

Returns the vertex of the given index. Throws if the index is out of range, if it less than 1 or greater than the number of vertices.

Folds over the vertices.

This method should be overridden in final classes.

Index with foreach on each vertx. Applies the side effecting function on the index with the value of each vertex. Note the function signature follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods' (accumulator, element) => B signature.

Maps the vertices of this polygon to an immutable Array like sequence of type B.

This method does nothing if the vertNum < 2. Foreach vertex applies the side effecting function to the previous vertex with each vertex. The previous vertex to the first vertex is the last vertex of the PolygonLike. Note the function signature (previous, vertex) => U follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods'(accumulator, element) => B signature.
