Field Summary

Fields

Modifier and Type	Field	Description
protected IntSupplier	m_supplierOrderId	A function that should be used to determine order id.
protected static AsyncNamedMap.OrderBy	NONE	The none-order singleton.
protected static Random	RANDOM	Random number generator.
protected static AsyncNamedMap.OrderBy	THREAD	The thread-order singleton.

Constructor Summary

Constructors

Modifier	Constructor	Description
protected	OrderBy(IntSupplier supplierOrderId)	Construct OrderBy instance.

Method Summary

Modifier and Type	Method	Description
static AsyncNamedMap.OrderBy	custom(IntSupplier supplierOrderId)	Return the order that will use the specified supplier to provide unit-of-order for each async operation.
int	getOrderId()	Return unit-of-order id.
static AsyncNamedMap.OrderBy	id(int nOrderId)	Return the order that will use the specified unit-of-order for all async operations, regardless of whether they were invoked from the same client thread or not.
static AsyncNamedMap.OrderBy	none()	Return the order that will allow the server to parallelize the execution of async operations across multiple threads, regardless of whether they were invoked from the same client thread or not.
static AsyncNamedMap.OrderBy	thread()	Return the order that will ensure that all operations invoked from the same client thread are executed on the server sequentially, using the same unit-of-order.

Field Detail

RANDOM

protected static final Random RANDOM

Random number generator.

THREAD

protected static final AsyncNamedMap.OrderBy THREAD

The thread-order singleton.

NONE

protected static final AsyncNamedMap.OrderBy NONE

The none-order singleton.

m_supplierOrderId

protected final IntSupplier m_supplierOrderId

A function that should be used to determine order id.

Constructor Detail

OrderBy

protected OrderBy(IntSupplier supplierOrderId)

Construct OrderBy instance.

Parameters:

supplierOrderId - the function that should be used to determine order id

Method Detail

getOrderId

public int getOrderId()

Return unit-of-order id.

Returns:

the unit-of-order id

thread

@Default
public static AsyncNamedMap.OrderBy thread()

Return the order that will ensure that all operations invoked from the same client thread are executed on the server sequentially, using the same unit-of-order.

This tends to provide best performance for fast, non-blocking operations and is the default order if the order is not specified.

Returns:

the default, thread-based ordering

none

public static AsyncNamedMap.OrderBy none()

Return the order that will allow the server to parallelize the execution of async operations across multiple threads, regardless of whether they were invoked from the same client thread or not.

Returns:

the order which allows the server to parallelize the execution of async operations across multiple threads

id

public static AsyncNamedMap.OrderBy id(int nOrderId)

Return the order that will use the specified unit-of-order for all async operations, regardless of whether they were invoked from the same client thread or not.

Parameters:

nOrderId - the unit-of-order to use for all operations

Returns:

the order which will use specified nOrderId for all operations

custom

public static AsyncNamedMap.OrderBy custom(IntSupplier supplierOrderId)

Return the order that will use the specified supplier to provide unit-of-order for each async operation.

Parameters:

supplierOrderId - the function that should be used to determine order id

Returns:

the order which will use specified function to provide unit-of-order for each async operation
