Class VkExternalMemoryProperties

java.lang.Object

org.lwjgl.system.Pointer.Default

org.lwjgl.system.Struct

org.lwjgl.vulkan.VkExternalMemoryProperties

All Implemented Interfaces:

org.lwjgl.system.Pointer

Direct Known Subclasses:

VkExternalMemoryPropertiesKHR

public class VkExternalMemoryProperties
extends org.lwjgl.system.Struct

Structure specifying external memory handle type capabilities.

Description

compatibleHandleTypes must include at least handleType. Inclusion of a handle type in compatibleHandleTypes does not imply the values returned in VkImageFormatProperties2 will be the same when VkPhysicalDeviceExternalImageFormatInfo::handleType is set to that type. The application is responsible for querying the capabilities of all handle types intended for concurrent use in a single image and intersecting them to obtain the compatible set of capabilities.

Member documentation

• externalMemoryFeatures – a bitmask of VkExternalMemoryFeatureFlagBits specifying the features of handleType.
• exportFromImportedHandleTypes – a bitmask of VkExternalMemoryHandleTypeFlagBits specifying which types of imported handle handleType can be exported from.
• compatibleHandleTypes – a bitmask of VkExternalMemoryHandleTypeFlagBits specifying handle types which can be specified at the same time as handleType when creating an image compatible with external memory.

Layout

 struct VkExternalMemoryProperties {
     VkExternalMemoryFeatureFlags externalMemoryFeatures;
     VkExternalMemoryHandleTypeFlags exportFromImportedHandleTypes;
     VkExternalMemoryHandleTypeFlags compatibleHandleTypes;

Constructor Detail

VkExternalMemoryProperties

public VkExternalMemoryProperties(java.nio.ByteBuffer container)

Creates a VkExternalMemoryProperties 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

externalMemoryFeatures

public int externalMemoryFeatures()

Returns the value of the externalMemoryFeatures field.

exportFromImportedHandleTypes

public int exportFromImportedHandleTypes()

Returns the value of the exportFromImportedHandleTypes field.

compatibleHandleTypes

public int compatibleHandleTypes()

Returns the value of the compatibleHandleTypes field.

create

public static VkExternalMemoryProperties create(long address)

Returns a new VkExternalMemoryProperties instance for the specified memory address.

createSafe

@Nullable
public static VkExternalMemoryProperties createSafe(long address)

Like create, but returns null if address is NULL.

create

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

Create a VkExternalMemoryProperties.Buffer instance at the specified memory.

Parameters:

address - the memory address

capacity - the buffer capacity

createSafe

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

Like create, but returns null if address is NULL.

nexternalMemoryFeatures

public static int nexternalMemoryFeatures(long struct)

Unsafe version of externalMemoryFeatures().

nexportFromImportedHandleTypes

public static int nexportFromImportedHandleTypes(long struct)

Unsafe version of exportFromImportedHandleTypes().

ncompatibleHandleTypes

public static int ncompatibleHandleTypes(long struct)

Unsafe version of compatibleHandleTypes().
