Class BufferPool

Namespace
easyar

BufferPool implements a memory pool that can be used for custom camera access and other functions requiring repeated allocation of same-sized memory, reducing memory allocation time.

BufferPool

Constructors

BufferPool

block_size is the byte size of each Buffer. capacity is the maximum number of Buffer.

void easyar_BufferPool__ctor(int block_size, int capacity, easyar_BufferPool * * Return)
BufferPool(int block_size, int capacity)
public BufferPool(int block_size, int capacity)
constructor(block_size: Int, capacity: Int)
+ (easyar_BufferPool *) create:(int)block_size capacity:(int)capacity
public convenience init(_ block_size: Int32, _ capacity: Int32)
public BufferPool(int block_size, int capacity)

Parameters

block_size Int32
capacity Int32

Methods

block_size

The byte size of each Buffer.

int easyar_BufferPool_block_size(const easyar_BufferPool * This)
int block_size()
public int block_size()
fun block_size(): Int
- (int)block_size
public func block_size() -> Int32
public virtual int block_size()

Returns

Int32

capacity

The maximum number of Buffer.

int easyar_BufferPool_capacity(const easyar_BufferPool * This)
int capacity()
public int capacity()
fun capacity(): Int
- (int)capacity
public func capacity() -> Int32
public virtual int capacity()

Returns

Int32

size

The current number of externally acquired Buffer.

int easyar_BufferPool_size(const easyar_BufferPool * This)
int size()
public int size()
fun size(): Int
- (int)size
public func size() -> Int32
public virtual int size()

Returns

Int32

tryAcquire

Attempts to acquire a memory block. If the current number of externally acquired Buffer has not reached the maximum number of Buffer, then retrieves or allocates a new Buffer; otherwise, returns empty.

void easyar_BufferPool_tryAcquire(easyar_BufferPool * This, easyar_OptionalOfBuffer * Return)
std::optional<std::shared_ptr<Buffer>> tryAcquire()
public @Nullable Buffer tryAcquire()
fun tryAcquire(): Buffer?
- (easyar_Buffer *)tryAcquire
public func tryAcquire() -> Buffer?
public virtual Optional<Buffer> tryAcquire()

Returns

Optional<Buffer>
