a
Direct3D

IDirect3DIndexBuffer9
COM
object.
sealed class

Can the content of this index buffer be updated?
public

type
|
bool
|
||
value
|
true
if
this
index
buffer
is
dynamic
and
its
content
can
be
updated.
false
if
this
index
buffer
is
static
and
its
content
cannot
be
updated.

Returns the raw handle value of the native resource that is contained in this object.

NativeHandle
{

type
|
IntPtr
|
||
value

The raw handle value. | ||
implements

Remarks:
The documentation of the implementing class will contain information on how to interpret the raw handle value.
Creates a new instance of DirectX9IndexBuffer.
public
constructor

DirectX9IndexBuffer
(IntPtr device,
int32 capacity)
|
||
params
|
device
|
The
IDirect3DDevice9*
COM
pointer. |
|
capacity
|
[>0]
|
The index buffer capacity, in indices. |
Acquires a strong reference to this disposable object.
[OwnerReturn, ThreadSafe]
|

public
method
|
AcquireTry
()
|
|||
type
|
IDisposable
|
|||
returns
|
this
if
a
new
strong
reference
has
been
acquired,
null
if
this
object
is
already
being
disposed.
|
|||
inherited
|
Disposable.AcquireTry
|
Remarks:
The object will not be actually disposed by calls to Dispose when there is at least one strong reference left. Code that calls the AcquireTry method is responsible for calling the Dispose method accordingly.
This method is not intended to be used in performance-critical code. It should only be used to high-level resource management.
Releases all resources held by this object if there are no more strong references to it, decrements the reference counter by one otherwise.
[Dispose, OwnerThis, ThreadSafe]

public
method
|
Dispose
()
|
|||
inherited
|
Disposable.Dispose
|
Remarks:
The Dispose method silently returns if the object has already been disposed.
Updates a range of indices in the buffer.

||
params
|
bufferIndex
|
[>=0]
|
Index of the first index buffer element to update. |
indices
|
[not-null]
|
An array holding the updated indices. | |
indicesOffset
|
[>=0]
|
Offset into indices to first index to read. | |
indicesCount
|
[>=0]
|
Total number of indices to read from indices. | |
flag
|
The update flag to apply. Defaults to Discard. | ||
