Package org.lwjgl.bgfx
Interface BGFXCaptureBeginCallbackI
- All Known Implementing Classes:
BGFXCaptureBeginCallback
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Called when video capture begins.

getCallInterface
Description copied from interface:CallbackI
Returns the libffi Call Interface for this callback function. [INTERNAL API]- Specified by:
getCallInterface
in interfaceCallbackI
- Returns:
- the CIF structure for this callback function
-
callback
default void callback(long ret, long args) Description copied from interface:CallbackI
The Java method that will be called from native code when the native callback function is invoked.- Specified by:
callback
in interfaceCallbackI
- Parameters:
ret
- a pointer to the memory used for the function's return value.If the function is declared as returning
void
, then this value is garbage and should not be used.Otherwise, the callback must fill the object to which this points, following the same special promotion behavior as
LibFFI.ffi_call(org.lwjgl.system.libffi.FFICIF, long, java.nio.ByteBuffer, org.lwjgl.PointerBuffer)
. That is, in most cases,ret
points to an object of exactly the size of the type specified whenCIF
was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume thatret
points to anffi_arg
object.args
- a vector of pointers to memory holding the arguments to the function
-
invoke
void invoke(long _this, int _width, int _height, int _pitch, int _format, boolean _yflip) Will be called when video capture begins.- Parameters:
_this
- the callback interface_width
- image width_height
- image height_pitch
- number of bytes to skip between the start of each horizontal line of the image_format
- texture format_yflip
- if true, image origin is bottom left
