Constructor & Destructor Documentation

PointPref() [1/3]

hdi::core::PointPref::PointPref

(

)

Constructs an empty PointPref object.

Author

GW

Date

09/2013

Note

To test if a PointPref object is empty, call isEmpty() on it

Empty PointPref objects do not relate to any actual preference data; they are designed to be "receivers" of some other PointPref object via the overloaded assignment operator. Empty PointPref objects are useless until such time (though it is safe to call any of their methods)

PointPref() [2/3]

hdi::core::PointPref::PointPref

(

const PointPref &

p_

)

Constructs a new PointPref object from an existing PointPref object (copy constructor)

Author

GW

Date

09/2013

Parameters

p_	Existing PointPref object

PointPref() [3/3]

hdi::core::PointPref::PointPref	(	const Point &	value_,
		const std::string &	name_ = ""
	)

Constructs a PointPref object, with new data, to be added to a container at a later time.

Author

GW

Date

09/2013

Parameters

value_	Initial point value
name_	Name for the data once it has been added to its container, as UTF-8

Note

The name_ argument can only be "" (omitted) if the object will be added directly to an ArrayPref object.

~PointPref()

virtual hdi::core::PointPref::~PointPref ( )

virtual

Destructs a PointPref object.

Member Function Documentation

clone()

virtual PointPref * hdi::core::PointPref::clone ( ) const

virtual

Convenience method to clone an PointPref object on the heap.

Author

GW

Date

10/2013

Returns

A pointer to the new PointPref object

Note

If you subclass PointPref, you MUST overload this method yourself! If you don't and/or your clone() method does not return an instance of your PointPref subclass, you will experience "object slicing" when adding the pref to a container.

Warning

The caller must manage the memory for the returned PointPref object.

Implements hdi::core::PrefData.

operator=()

virtual PointPref & hdi::core::PointPref::operator= ( const PointPref &  rhs_ )

virtual

Allows one PointPref object to be assigned from another.

Author

GW

Date

09/2013

Parameters

rhs_	Righthand side of the = operator; the object to copy values from

Returns

The target PointPref object, but with its value updated to match that of rhs_

point()

virtual Point hdi::core::PointPref::point ( ) const

virtual

Gets the point for this object.

Author

GW

Date

09/2013

Returns

The Point object being described by this wrapper

setPoint()

virtual bool hdi::core::PointPref::setPoint ( const Point &  pt_ )

virtual

Sets the point for this object.

Author

Date

Parameters

pt_	New point value

Returns

true if the point is successfully updated, or false otherwise
