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.

Index with foreach on the data elements. Performs a side effecting function on the index and each element of the data sequence. It takes a function as a parameter. The function may return Unit. If it does return a non Unit value it is discarded. The [U] type parameter is there just to avoid warnings about discarded values and can be ignored by method users. The method has 2 versions / name overloads. The default start for the index is 0 if just the function parameter is passed. The second version name overload takes an Int for the first parameter list, to set the start value of the index. 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.

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

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

Specialised map to an immutable SeqImut of B. For SeqGen dataMap is the same as map, but for other structures it will be different, for example a PolygonLike will map to another PolgonLike.

Foreachs over the tail of the data sequence.

foldLeft over the tail of the data sequence.

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.

Reverses the order of the elements in a new Array[Double] which is returned.

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.

Checks this polygon has at least 3 vertices.

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.
