PolygonLike

Gives the final type of this class.

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

Returns a side of the appropriate type for the PolygonLike from the goven index. The index cycles.

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

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.

Optionally maps the vertices of this PolygonLike to vertices of a new to PolygonLike class of type BB. If the new PolygonLike has at least 3 vertices returns Some else returns None.

Returns the vertex of the given index. Cycles around if the index is out of range, vert 3 retruns vert 0 on a triangle.

This method should be overridden in final classes.

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.

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

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.

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. 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.

Accesses the specifying sequence element by a 0 based index.

Foreachs over the inner of the specifying sequence, excludes the first and last element. Performs a side effecting function on each element of the tail of the specifying sequence in order.

Last element of the specifying sequence.

The number of data elements in the defining sequence. These collections use underlying mutable Arrays and ArrayBuffers. The length of the underlying Array will be a multiple of this number.

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.

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.
