Creates a new, autoreleased OFValue containing the specified pointer.

Only the raw value of the pointer is stored and no data will be copied.

Parameters

pointer The pointer the OFValue should contain

Returns: A new, autoreleased OFValue

Reimplemented in OFNumber.

◆ valueWithRange:

+ (instancetype) valueWithRange: (OFRange) range

Creates a new, autoreleased OFValue containing the specified range.

Parameters

range The range the OFValue should contain

Returns: A new, autoreleased OFValue

Reimplemented in OFNumber.

◆ valueWithRect:

+ (instancetype) valueWithRect: (OFRect) rect

Creates a new, autoreleased OFValue containing the specified rectangle.

Parameters

rect	The rectangle the OFValue should contain

Returns: A new, autoreleased OFValue

Reimplemented in OFNumber.

◆ valueWithSize:

+ (instancetype) valueWithSize: (OFSize) size

Creates a new, autoreleased OFValue containing the specified size.

Parameters

size	The size the OFValue should contain

Returns: A new, autoreleased OFValue

Reimplemented in OFNumber.

◆ valueWithVector3D:

+ (instancetype) valueWithVector3D: (OFVector3D) vector3D

Creates a new, autoreleased OFValue containing the specified 3D vector.

Parameters

vector3D The 3D vector the OFValue should contain

Returns: A new, autoreleased OFValue

◆ valueWithVector4D:

+ (instancetype) valueWithVector4D: (OFVector4D) vector4D

Creates a new, autoreleased OFValue containing the specified 4D vector.

Parameters

vector4D The 4D vector the OFValue should contain

Returns: A new, autoreleased OFValue

OFOutOfRangeException The value is not OFVector4D-sized
