public class DriverDirectModeFrameTiming
extends org.lwjgl.system.Struct

Frame timing data provided by direct mode drivers.

Member documentation

• m_nSize – sSet to sizeof( DriverDirectMode_FrameTiming )
• m_nNumFramePresents – number of times frame was presented
• m_nNumMisPresented – number of times frame was presented on a vsync other than it was originally predicted to
• m_nNumDroppedFrames – number of additional times previous frame was scanned out (i.e. compositor missed vsync)

Constructor Detail

DriverDirectModeFrameTiming

public DriverDirectModeFrameTiming(java.nio.ByteBuffer container)

Creates a DriverDirectModeFrameTiming instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

The created instance holds a strong reference to the container object.

Method Detail

sizeof

public int sizeof()

Specified by:

sizeof in class org.lwjgl.system.Struct

m_nSize

public int m_nSize()

Returns the value of the m_nSize field.

m_nNumFramePresents

public int m_nNumFramePresents()

Returns the value of the m_nNumFramePresents field.

m_nNumMisPresented

public int m_nNumMisPresented()

Returns the value of the m_nNumMisPresented field.

m_nNumDroppedFrames

public int m_nNumDroppedFrames()

Returns the value of the m_nNumDroppedFrames field.

m_nReprojectionFlags

public int m_nReprojectionFlags()

Returns the value of the m_nReprojectionFlags field.

create

public static DriverDirectModeFrameTiming create(long address)

Returns a new DriverDirectModeFrameTiming instance for the specified memory address.

createSafe

@Nullable
public static DriverDirectModeFrameTiming createSafe(long address)

Like create, but returns null if address is NULL.

create

public static DriverDirectModeFrameTiming.Buffer create(long address,
                                                        int capacity)

Parameters:

address - the memory address

capacity - the buffer capacity

createSafe

@Nullable
public static DriverDirectModeFrameTiming.Buffer createSafe(long address,
                                                            int capacity)

Like create, but returns null if address is NULL.
