Method Details

close

void close()
    throws VulkanException

Description copied from interface: VulkanHandleType

Destroy the object.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface VulkanHandleType

Throws:

VulkanException - On errors

enumeratePhysicalDevices

Stream<VulkanPhysicalDeviceType> enumeratePhysicalDevices()
                                                   throws VulkanException

Returns:

The available physical devices

Throws:

VulkanException - On errors

physicalDevices

default List<VulkanPhysicalDeviceType> physicalDevices()
                                                throws VulkanException

Returns:

The available physical devices

Throws:

VulkanException - On errors

apiVersionMaximumSupported

VulkanVersion apiVersionMaximumSupported()

Find the maximum API version supported. This is essentially the same as VulkanInstanceProviderType.findSupportedInstanceVersion(), and does not indicate that this particular instance will allow function calls that require that version.

Returns:

The maximum API version supported

See Also:

• apiVersionUsed()

apiVersionUsed

VulkanVersion apiVersionUsed()

Return the API version that this instance will support. This is the version that the user actually requested, and therefore defines the upper bound for the Vulkan API version that can be used with this instance.

Returns:

The API version that this instance is configured to use

enabledExtensions

Map<String, VulkanExtensionType> enabledExtensions()
                                            throws VulkanException

Returns:

The enabled extensions for the instance

Throws:

VulkanException - On errors

findEnabledExtension

default <T extends VulkanExtensionType> Optional<T> findEnabledExtension(String name,
 Class<T> clazz)
                                                                  throws VulkanException

Find and cast an extension with a given name to the correct API type.

Type Parameters:

T - The precise type

Parameters:

name - The extension name

clazz - The intended extension type

Returns:

The extension with the correct type, or nothing if the extension either did not exist or did not have the right type

Throws:

VulkanException - On errors
