A path is a sequence of lines and curves that may either form a closed shape or be openended.
To use a path, you can create an empty one, then add lines and curves to it to create shapes, then it can be rendered by a Graphics context or used for geometric operations.
e.g.
A path object can actually contain multiple subpaths, which may themselves be open or closed.
Path::Path  (  ) 
Creates an empty path.
Path::Path  (  const Path &  ) 
Creates a copy of another path.
Path::~Path  (  ) 
Destructor.

noexcept 
Move constructor.

noexcept 

noexcept 

noexcept 
Returns true if the path doesn't contain any lines or curves.

noexcept 
Returns the smallest rectangle that contains all points within the path.

noexcept 
Returns the smallest rectangle that contains all points within the path after it's been transformed with the given transform matrix.
bool Path::contains  (  float  x, 
float  y,  
float  tolerance = defaultToleranceForTesting 

)  const 
Checks whether a point lies within the path.
This is only relevant for closed paths (see closeSubPath()), and may produce false results if used on a path which has open subpaths.
The path's winding rule is taken into account by this method.
The tolerance parameter is the maximum error allowed when flattening the path, so this method could return a false positive when your point is up to this distance outside the path's boundary.
bool Path::contains  (  Point< float >  point, 
float  tolerance = defaultToleranceForTesting 

)  const 
Checks whether a point lies within the path.
This is only relevant for closed paths (see closeSubPath()), and may produce false results if used on a path which has open subpaths.
The path's winding rule is taken into account by this method.
The tolerance parameter is the maximum error allowed when flattening the path, so this method could return a false positive when your point is up to this distance outside the path's boundary.
bool Path::intersectsLine  (  Line< float >  line, 
float  tolerance = defaultToleranceForTesting 

) 
Checks whether a line crosses the path.
This will return positive if the line crosses any of the paths constituent lines or curves. It doesn't take into account whether the line is inside or outside the path, or whether the path is open or closed.
The tolerance parameter is the maximum error allowed when flattening the path, so this method could return a false positive when your point is up to this distance outside the path's boundary.
Cuts off parts of a line to keep the parts that are either inside or outside this path.
Note that this isn't smart enough to cope with situations where the line would need to be cut into multiple pieces to correctly clip against a reentrant shape.
line  the line to clip 
keepSectionOutsidePath  if true, it's the section outside the path that will be kept; if false its the section inside the path 
float Path::getLength  (  const AffineTransform &  transform = AffineTransform() , 
float  tolerance = defaultToleranceForMeasurement 

)  const 
Returns the length of the path.
Point<float> Path::getPointAlongPath  (  float  distanceFromStart, 
const AffineTransform &  transform = AffineTransform() , 

float  tolerance = defaultToleranceForMeasurement 

)  const 
Returns a point that is the specified distance along the path.
If the distance is greater than the total length of the path, this will return the end point.
float Path::getNearestPoint  (  Point< float >  targetPoint, 
Point< float > &  pointOnPath,  
const AffineTransform &  transform = AffineTransform() , 

float  tolerance = defaultToleranceForMeasurement 

)  const 
Finds the point along the path which is nearest to a given position.
This sets pointOnPath to the nearest point, and returns the distance of this point from the start of the path.

noexcept 
Removes all lines and curves, resetting the path completely.
void Path::startNewSubPath  (  float  startX, 
float  startY  
) 
Begins a new subpath with a given starting position.
This will move the path's current position to the coordinates passed in and make it ready to draw lines or curves starting from this position.
After adding whatever lines and curves are needed, you can either close the current subpath using closeSubPath() or call startNewSubPath() to move to a new subpath, leaving the old one openended.
void Path::startNewSubPath  (  Point< float >  start  ) 
Begins a new subpath with a given starting position.
This will move the path's current position to the coordinates passed in and make it ready to draw lines or curves starting from this position.
After adding whatever lines and curves are needed, you can either close the current subpath using closeSubPath() or call startNewSubPath() to move to a new subpath, leaving the old one openended.
void Path::closeSubPath  (  ) 
Closes a the current subpath with a line back to its startpoint.
When creating a closed shape such as a triangle, don't use 3 lineTo() calls  instead use two lineTo() calls, followed by a closeSubPath() to join the final point back to the start.
This ensures that closes shapes are recognised as such, and this is important for tasks like drawing strokes, which needs to know whether to draw endcaps or not.
void Path::lineTo  (  float  endX, 
float  endY  
) 
Adds a line from the shape's last position to a new endpoint.

bool  startAsNewSubPath = false 

) 
Adds an elliptical arc to the current path.
Note that when specifying the start and end angles, the curve will be drawn either clockwise or anticlockwise according to whether the end angle is greater than the start. This means that sometimes you may need to use values greater than 2*Pi for the end angle.

width  the width of the rectangle in which the elliptical outline fits

toRadians  the angle (clockwise) in radians at which to end the arc segment (where 0 is the topcentre of the ellipse). This angle can be greater than 2*Pi, so for example to draw a curve clockwise from the 9 o'clock position to the 3 o'clock position via 12 o'clock, you'd use 1.5*Pi and 2.5*Pi as the start and finish points.

float  fromRadians,  
float  toRadians,

The shape is added as a new subpath. (Any currently open paths will be left open).

noexcept 
Swaps the contents of this path with another one.

void Path::preallocateSpace  (  int  numExtraCoordsToMakeSpaceFor  ) 
Preallocates enough space for adding the given number of coordinates to the path.
If you're about to add a large number of lines or curves to the path, it can make the task much more efficient to call this first and avoid costly reallocations as the structure grows. The actual value to pass is a bit tricky to calculate because the space required depends on what you're adding  e.g. each lineTo() or startNewSubPath() will require 3 coords (x, y and a type marker). Each quadraticTo() will need 5, and a cubicTo() will require 7. Closing a subpath will require 1.

noexcept 
Applies a 2D transform to all the vertices in the path.

noexcept 
Rescales this path to make it fit neatly into a given space.
This is effectively a quick way of calling applyTransform (getTransformToScaleToFit (x, y, w, h, preserveProportions))

preserveProportions  if true, it will fit the path into the space without altering its horizontal/vertical scale ratio; if false, it will distort the path to fill the specified ratio both horizontally and vertically 
justificationType  if the proportions are preseved, the resultant path may be smaller than the available rectangle, so this describes how it should be positioned within the space. 
Path Path::createPathWithRoundedCorners  (  float  cornerRadius  )  const 
Creates a version of this path where all sharp corners have been replaced by curves.
Wherever two lines meet at an angle, this will replace the corner with a curve of the given radius.

noexcept 
Changes the windingrule to be used when filling the path.
If set to true (which is the default), then the path uses a nonzerowinding rule to determine which points are inside the path. If set to false, it uses an alternatewinding rule.
The windingrule comes into play when areas of the shape overlap other areas, and determines whether the overlapping regions are considered to be inside or outside.
Changing this value just sets a flag  it doesn't affect the contents of the path.
bool Path::isUsingNonZeroWinding  (  )  const 
Returns the flag that indicates whether the path should use a nonzero winding rule.
The default for a new path is true.
void Path::loadPathFromStream  (  InputStream &  source  ) 
Loads a stored path from a data stream.
The data in the stream must have been written using writePathToStream().
Note that this will append the stored path to whatever is currently in this path, so you might need to call clear() beforehand.
void Path::loadPathFromData  (  const void *  data, 
size_t  numberOfBytes  
) 
Loads a stored path from a block of data.
This is similar to loadPathFromStream(), but just reads from a block of data. Useful if you're including stored shapes in your code as a block of static data.
void Path::writePathToStream  (  OutputStream &  destination  )  const 
Stores the path by writing it out to a stream.
After writing out a path, you can reload it using loadPathFromStream().
String Path::toString  (  )  const 
Creates a string containing a textual representation of this path.
void Path::restoreFromString  (  StringRef  stringVersion  ) 
Restores this path from a string that was created with the toString() method.
