public class Allocator
extends PropertyHolder

Memory is usually created by allocators with a gst_allocator_alloc()
method call. When %NULL is used as the allocator, the default allocator will
be used.

New allocators can be registered with gst_allocator_register().
Allocators are identified by name and can be retrieved with
gst_allocator_find(). gst_allocator_set_default() can be used to change the
default allocator.

New memory can be created with gst_memory_new_wrapped() that wraps the memory
allocated elsewhere.

Allocator

public Allocator(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

alloc

public Memory alloc(long size,
 @Nullable
 AllocationParams params)

Use @allocator to allocate a new memory block with memory that is at least
@size big.

The optional @params can specify the prefix and padding for the memory. If
%NULL is passed, no flags, no extra prefix/padding and a default alignment is
used.

The prefix/padding will be filled with 0 if flags contains
#GST_MEMORY_FLAG_ZERO_PREFIXED and #GST_MEMORY_FLAG_ZERO_PADDED respectively.

When @allocator is %NULL, the default allocator will be used.

The alignment in @params is given as a bitmask so that @align + 1 equals
the amount of bytes to align to. For example, to align to 8 bytes,
use an alignment of 7.

Parameter:

size - size of the visible memory area

params - optional parameters

Gibt zurück:

a new #GstMemory.

free

public void free(@Nonnull
 Memory memory)

Free @memory that was previously allocated with gst_allocator_alloc().

Parameter:

memory - the memory to free

setDefault

public void setDefault()

Set the default allocator.

find

public static Allocator find(@Nullable
 Str name)

Find a previously registered allocator with @name. When @name is %NULL, the
default allocator will be returned.

Parameter:

name - the name of the allocator

Gibt zurück:

a #GstAllocator or %NULL when the allocator with @name was not registered.

register

public static void register(@Nonnull
 Str name,
 @Nonnull
 Allocator allocator)

Registers the memory @allocator with @name.

Parameter:

name - the name of the allocator

allocator - #GstAllocator

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
