Constructor & Destructor Documentation

Path2DF() [1/3]

ot::Path2DF::Path2DF

(

)

Default constructor.

Path2DF() [2/3]

ot::Path2DF::Path2DF

(

const Point2DD &

_startPos

)

Assignment constructor.

Parameters

_startPos

The initial position of the path (same as calling moveTo())

Path2DF() [3/3]

ot::Path2DF::Path2DF

Member Function Documentation

addToJsonObject()

void ot::Path2DF::addToJsonObject ( ot::JsonValue & _object, ot::JsonAllocator & _allocator ) const

overridevirtual

Add the object contents to the provided JSON object.

Parameters

_object	Json object reference
_allocator	Allocator

Implements ot::Serializable.

berzierTo()

void ot::Path2DF::berzierTo	(	const Point2DD &	_ct1,
		const Point2DD &	_ct2,
		const Point2DD &	_dest )

Adds a berzier curve from the current position to the provided destination by taking the two control points into account. The current position will be set to the destination.

Parameters

_ct1	Control point 1.
_ct2	Control point 2.
_dest	The curve destination.

clear()

void ot::Path2DF::clear

(

void

)

Remove all the entries from the path.

Note

Note that the current position wont be changed.

getEntries()

const std::list< PathEntry > & ot::Path2DF::getEntries ( void ) const

inline

Returns the current entries.

isClosed()

bool ot::Path2DF::isClosed

(

void

)

Returns true if the path contains at least one entry, the entries are interconnected (end of a entry is start of another) and the start point is also the final end point.

lineTo()

void ot::Path2DF::lineTo

(

const Point2DD &

_dest

)

Adds a line from the current position to the provided destination. The current position will be set to the destination.

Parameters

_dest

The line destination.

moveBy()

void ot::Path2DF::moveBy ( const Point2DD & _d )

inline

Moves the current position by the delta.

Parameters

_d	Move distance (incremental).

moveTo()

void ot::Path2DF::moveTo ( const Point2DD & _pos )

inline

Moves the current position. No line will be added.

Parameters

_pos	The position to move to (absolute).

operator=()

ot::Path2DF & ot::Path2DF::operator=

(

const Path2DF &

_other

)

Assignment operator.

setFromJsonObject()

void ot::Path2DF::setFromJsonObject ( const ot::ConstJsonObject & _object )

overridevirtual

Will set the object contents from the provided JSON object.

Parameters

_object

The JSON object containing the information

Exceptions

Will	throw an exception if the provided object is not valid (members missing or invalid types)

Implements ot::Serializable.
