Class DmabufFormats

java.lang.Object

org.javagi.base.ProxyInstance

org.gnome.gdk.DmabufFormats

All Implemented Interfaces:

Proxy

@Generated("org.javagi.JavaGI")
public class DmabufFormats
extends ProxyInstance

Provides information about supported DMA buffer formats.

You can query whether a given format is supported with contains(int, long) and you can iterate over the list of all supported formats with getNFormats() and getFormat(long, Out, Out).

The list of supported formats is sorted by preference, with the best formats coming first.

The list may contains (format, modifier) pairs where the modifier is DMA_FORMAT_MOD_INVALID, indicating that implicit modifiers may be used with this format.

See DmabufTextureBuilder for more information about DMA buffers.

Note that DMA buffers only exist on Linux.

4.14

Constructor Details

DmabufFormats

public DmabufFormats(MemorySegment address)

Create a DmabufFormats proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static @Nullable Type getType()

Get the GType of the DmabufFormats class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

contains

public boolean contains(int fourcc,
 long modifier)

Returns whether a given format is contained in formats.

Parameters:

fourcc - a format code

modifier - a format modifier

Returns:

TRUE if the format specified by the arguments is part of this DmabufFormats

Since:

4.14

equal

public boolean equal(@Nullable DmabufFormats formats2)

Returns whether this DmabufFormats and formats2 contain the same dmabuf formats, in the same order.

Parameters:

formats2 - another GdkDmabufFormats

Returns:

TRUE if this DmabufFormats and formats2 are equal

Since:

4.14

getFormat

public void getFormat(long idx,
 Out<Integer> fourcc,
 Out<Long> modifier)

Gets the fourcc code and modifier for a format that is contained in formats.

Parameters:

idx - the index of the format to return

fourcc - return location for the format code

modifier - return location for the format modifier

Since:

4.14

getNFormats

public long getNFormats()

Returns the number of formats that the this DmabufFormats object contains.

Note that DMA buffers are a Linux concept, so on other platforms, getNFormats() will always return zero.

Returns:

the number of formats

Since:

4.14

ref

public DmabufFormats ref()

Increases the reference count of formats.

Returns:

the passed-in object

Since:

4.14

unref

public void unref()

Decreases the reference count of formats.

When the reference count reaches zero, the object is freed.
