LinePathBase

Gives the final type of this class.

Prepends a single vertex of type VT. Returns a new extended LinePathBase.

Prepends a single vertex of type VT. Returns a new extended LinePathBase.

Appends a single vertex of type VT. Returns a new extended LinePathBase.

Appends another LinePathBase of this type. Returns a new extended LinePathBase.

Appends the reverse vertex order of another LinePathBase of this type. Returns a new extended LinePathBase. The < character after the ++ indicates that is the operand that is being reversed.

Appends the tail (without its first point) of the operand LinePathBase of this type. The ++ indicates to append a sequence. The trailing indicates to drop the first point of the operand.

Reverses this line path and then appends the operand. The < character between the + characters indicates that it this line path that is reversed.

Reverses this line path and then appends the operand. The < character between the + characters indicates that it this line path that is reversed.

This line path with the last vertex removed. This can be useful for borders where the end points may show up in multiple line paths and therefore sometimes need to be excluded when appending.

This line path with the first and last vertex's removed. This can be useful for borders where the end points may show up in multiple line paths* and therefore sometimes need to be excluded when appending.

This line path with the first vertex removed. This can be useful for borders where the end points may show up in multiple line paths and therefore sometimes need to be excluded when appending.

Closes this LinePathBase into a PolygonBase by adding a LSegBase from the last vertex to the first.

Appends the operand point and closes the path into a PolygonBase of the matching type. +% indicates to append a point. The enclosing '|' characters indicate to close the line path into a polygon.

Appends the reverse vertex order of another LinePathBase of this type. Returns a new extended closed PolygonBase. The < after the ++ indicates it is the operand to be reversed.

Appends the operand LinePathBase of this type and closes the path into a PolygonBase of the matching type. ++ indicates to append a sequence. The enclosing '|' characters indicate to close the line path into a polygon.

Appends the tail (without its first point) of the operand LinePathBase of this type, closing the path to a PolygonBase of the matching type. ++ indicates append a sequence. The - between the + characters indicates to drop the first point of the operand. The enclosing '|' characters indicate to close the line path into a polygon.

Reverses this line path, appends the operand line path and then closes to a polygon. The < character between the + characters indicates that this line is reversed. The | characters at the begining and the end indicate to close to a polygon.

Appends a single vertex of type A. Returns a PolygonBase.

Appends the init of another LinePathBase of this type to the init of this LinePathBase, closing the path to return a PolygonBase of the matching type. The - before the ++ indicates to drop the last point of this line path. The - after the ++ indicates to drop the end point of the operand.

maps to a LinePathBase. This map operates on a single LinePathBase its not to be confused with a map on Arr of LinePathBases.

The number of vertices.

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

String for element, can be overridden.

foldLeft over the specifying sequence.

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 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.

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.

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.

Mutates an element in the Arr at the given index. This method should rarely be needed by end users, but is used by the initialisation and factory methods.

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.

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

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.

Accesses the specifying sequence element by a 0 based index. For Sequs this will an alternative name for apply.

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. For Sequs this will be an alternative name for length.

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

String specifying the type of this object.
