Method Summary

Modifier and Type	Method	Description
static void	allowBlocking(Runnable runnable)
static Executor	allowBlockingExecutor()	Returns an Executor that when supplied a task, will allow it to invoke blocking calls, even if the invoking context was already registered as non blocking.
static <V> void	blockingConsume(V consumed)	Helper method that "blocks" as dictated by block hound but in actuality does nothing.
static boolean	currentThreadRequiresNonBlocking()	Returns true if the current thread at this time requires all invocations to be non blocking
static void	ensureNonBlocking(Runnable runnable)	Invokes the provided Runnable in a scope that guarantees that the current thread is not blocked.
static <V> V	ensureNonBlocking(Supplier<V> supplier)	Invokes the provided Supplier in a scope that guarantees that the current thread is not blocked.
static Executor	ensureNonBlockingExecutor()	Returns an Executor that when supplied a task, will guarantee that task does not block when invoked.

Method Details

currentThreadRequiresNonBlocking

public static boolean currentThreadRequiresNonBlocking()

Returns true if the current thread at this time requires all invocations to be non blocking

ensureNonBlocking

public static <V> V ensureNonBlocking(Supplier<V> supplier)

Invokes the provided Supplier in a scope that guarantees that the current thread is not blocked. If blocking is found the invoking test will fail.

ensureNonBlocking

public static void ensureNonBlocking(Runnable runnable)

Invokes the provided Runnable in a scope that guarantees that the current thread is not blocked. If blocking is found the invoking test will fail.

allowBlocking

public static void allowBlocking(Runnable runnable)

ensureNonBlockingExecutor

public static Executor ensureNonBlockingExecutor()

Returns an Executor that when supplied a task, will guarantee that task does not block when invoked. If the task does block it will fail the invoking test.

allowBlockingExecutor

public static Executor allowBlockingExecutor()

Returns an Executor that when supplied a task, will allow it to invoke blocking calls, even if the invoking context was already registered as non blocking. Useful to mock submission to a blocking executor.

blockingConsume

public static <V> void blockingConsume(V consumed)

Helper method that "blocks" as dictated by block hound but in actuality does nothing. This is useful to detect if the given code is actually be invoked in an method that allows for blocking or not.

Type Parameters:

V - whatever desired type is

Parameters:

consumed - an argument useful for making this method a `Consumer` via method reference
