Class ParentBufferMeta

org.freedesktop.gstreamer.gst.ParentBufferMeta

All Implemented Interfaces:

Proxy

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

The GstParentBufferMeta is a GstMeta which can be attached to a GstBuffer to hold a reference to another buffer that is only released when the child GstBuffer is released.

Typically, GstParentBufferMeta is used when the child buffer is directly using the GstMemory of the parent buffer, and wants to prevent the parent buffer from being returned to a buffer pool until the GstMemory is available for re-use.

public ParentBufferMeta(MemorySegment address)

Create a ParentBufferMeta proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ParentBufferMeta

public ParentBufferMeta(Arena arena)

Allocate a new ParentBufferMeta.

Parameters:

arena - to control the memory allocation scope

ParentBufferMeta

public ParentBufferMeta()

The value of the field parent

writeParent

public void writeParent(@Nullable Meta parent)

Write a value in the field parent.

Parameters:

parent - The new value for the field parent

readBuffer

public Buffer readBuffer()

Read the value of the field buffer.

Returns:

The value of the field buffer

writeBuffer

public void writeBuffer(Buffer buffer)

Write a value in the field buffer.

Parameters:

buffer - The new value for the field buffer

getInfo
