Constructor Detail

VkMemoryHeap

public VkMemoryHeap(java.nio.ByteBuffer container)

Creates a VkMemoryHeap 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()

Description copied from class: Struct

Returns sizeof(struct).

Specified by:

sizeof in class Struct

size

public long size()

Returns the value of the size field.

flags

public int flags()

Returns the value of the flags field.

create

public static VkMemoryHeap create(long address)

Returns a new VkMemoryHeap instance for the specified memory address.

createSafe

@Nullable
public static VkMemoryHeap createSafe(long address)

Like create, but returns null if address is NULL.

create

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

Create a VkMemoryHeap.Buffer instance at the specified memory.

Parameters:

address - the memory address

capacity - the buffer capacity

createSafe

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

Like create, but returns null if address is NULL.

nsize

public static long nsize(long struct)

Unsafe version of size().

nflags

public static int nflags(long struct)

Unsafe version of flags().
