Detailed Description

Allows for storage of 2D sizes.

Constructor & Destructor Documentation

SizePref() [1/3]

hdi::core::SizePref::SizePref

(

)

Constructs an empty SizePref object.

Author

GW

Date

09/2013

Note

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

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

SizePref() [2/3]

hdi::core::SizePref::SizePref

(

const SizePref &

s_

)

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

Author

GW

Date

09/2013

Parameters

s_	Existing SizePref object

SizePref() [3/3]

hdi::core::SizePref::SizePref	(	const Size &	value_,
		const std::string &	name_ = ""
	)

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

Author

GW

Date

09/2013

Parameters

value_	Initial size 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.

~SizePref()

virtual hdi::core::SizePref::~SizePref ( )

virtual

Destructs a SizePref object.

Member Function Documentation

clone()

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

virtual

Convenience method to clone an SizePref object on the heap.

Author

GW

Date

10/2013

Returns

A pointer to the new SizePref object

Note

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

Warning

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

Implements hdi::core::PrefData.

operator=()

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

virtual

Allows one SizePref 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 SizePref object, but with its value updated to match that of rhs_

setSize()

virtual bool hdi::core::SizePref::setSize ( const Size &  s_ )

virtual

Sets the size for this object.

Author

Date

09/2013

Parameters

s_	New size value

Returns

true if the size is successfully updated, or false otherwise

size()

virtual Size hdi::core::SizePref::size ( ) const

virtual

Gets the size for this object.

Returns

The Size object being described by this wrapper
