Record Class SDL_JoyDeviceEvent

java.lang.Object

java.lang.Record

club.doki7.sdl3.datatype.SDL_JoyDeviceEvent

All Implemented Interfaces:

IPointer, ISDL_JoyDeviceEvent

@ValueBasedCandidate
@UnsafeConstructor
public record SDL_JoyDeviceEvent(@NotNull MemorySegment segment)
extends Record
implements ISDL_JoyDeviceEvent

Joystick device event structure (event.jdevice.*)

SDL will send JOYSTICK_ADDED events for devices that are already plugged in during SDL_Init.

Since: This struct is available since SDL 3.2.0.

See also:

• SDL_GamepadDeviceEvent

Structure

typedef struct SDL_JoyDeviceEvent {
    SDL_EventType type;
    Uint32 reserved;
    Uint64 timestamp;
    SDL_JoystickID which;
} SDL_JoyDeviceEvent;

Contracts

The property segment() should always be not-null (segment != NULL && !segment.equals(MemorySegment.NULL)), and properly aligned to LAYOUT.byteAlignment() bytes. To represent null pointer, you may use a Java null instead. See the documentation of IPointer.segment() for more details.

The constructor of this class is marked as UnsafeConstructor, because it does not perform any runtime check. The constructor can be useful for automatic code generators.

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

segment

@NotNull
public @NotNull MemorySegment segment()

Returns the value of the segment record component.

Specified by:

segment in interface IPointer

Returns:

the value of the segment record component
