Constructor Details

Size

public Size(MemorySegment address)

Create a Size proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Size

public Size(Arena arena)

Allocate a new Size.

Parameters:

arena - to control the memory allocation scope

Size

public Size()

Allocate a new Size. The memory is allocated with Arena.ofAuto().

Size

public Size(float width,
 float height,
 Arena arena)

Allocate a new Size with the fields set to the provided values.

Parameters:

width - value for the field width

height - value for the field height

arena - to control the memory allocation scope

Size

public Size(float width,
 float height)

Allocate a new Size with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

width - value for the field width

height - value for the field height

Method Details

getType

public static @Nullable Type getType()
