PolygonLikeDblN

Gives the final type of this class.

Builder helper method that provides a longer array, with the underlying array copied into the new extended Array.

Utility method to append element on to an ArrayBuffer[Double]. End users should rarely need to use this method.

The number of atomic values, Ints, Doubles, Longs etc that specify / construct an element of this immutable flat Array based collection class.

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

FlatMaps the vertices of this PolygonLike to a new to PolygonLike class of type BB.

Maps the vertices of this PolygonLike to a new to PolygonLike class of type BB.

Checks if 2 values of the specifying sequence are equal.

specifying -sequence fold.

Performs a side effecting function on each element of the specifying 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.

Index with foreach on the the specifying sequence elements. Performs a side effecting function on the index and each element of the specifying sequence. It takes a function as a parameter.

Accesses the specifying sequence element by a 0 based index.

Last element of the specifying sequence.

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

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

Reverses the order of the elements of the specifying sequence.

Performs a side effecting function on each element of the specifying-sequence in reverse order. 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.

FoldLeft over the tail of the specifying sequence.

Foreachs over the tail of the specifying sequence. Performs a side effecting function on each element of the tail of the specifying sequence in order.

Returns a string representation of the object.

The default representation is platform dependent.

String specifying the type of this object.

The total number of atomic values, Ints, Doubles, Longs etc in the backing Array.

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

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

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.

Performs the side effecting function on the value of each vertex.

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.

The number of vertices and also the number of sides in this Polygon.

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.
