Method Details

buffer

@Contract(pure=true)
public static <T> AsyncPredicate<T> buffer(AsyncPredicate<T> actual)

buffer

@Contract(pure=true)
public static <T> AsyncPredicate<T> buffer(int maxParallelCalls,
 int maxBufferedCalls,
 AsyncPredicate<T> predicate)

ofExecutor

@Contract(pure=true)
public static <T> AsyncPredicate<T> ofExecutor(AsyncExecutor executor,
 AsyncPredicate<T> predicate)

and

public static <T> AsyncPredicate<T> and(Collection<AsyncPredicate<? super T>> predicates)

Returns a composed AsyncPredicate that represents a logical AND of all predicates in a given collection

Unlike Java's Predicate.and(Predicate) this method does not provide short-circuit. If either predicate returns an exceptionally completed promise, the combined asynchronous predicate also returns an exceptionally completed promise

Parameters:

predicates - a collection of AsyncPredicates that will be logically ANDed

Returns:

a composed AsyncPredicate that represents a logical AND of asynchronous predicates in a given collection

and

public static <T> AsyncPredicate<T> and()

Returns an AsyncPredicate that always returns promise of true

See Also:

• and(Collection)

and

public static <T> AsyncPredicate<T> and(AsyncPredicate<? super T> predicate1)

Returns a given asynchronous predicate

A shortcut for and(AsyncPredicate[])

See Also:

• and(Collection)
• and(AsyncPredicate[])

and

public static <T> AsyncPredicate<T> and(AsyncPredicate<? super T> predicate1,
 AsyncPredicate<? super T> predicate2)

An optimization for and(AsyncPredicate[])

See Also:

• and(Collection)
• and(AsyncPredicate[])

and

@SafeVarargs
public static <T> AsyncPredicate<T> and(AsyncPredicate<? super T>... predicates)

Returns a composed AsyncPredicate that represents a logical AND of all predicates in a given array

See Also:

• and(Collection)

or

public static <T> AsyncPredicate<T> or(Collection<AsyncPredicate<? super T>> predicates)

Returns a composed AsyncPredicate that represents a logical OR of all predicates in a given collection

Unlike Java's Predicate.or(Predicate) this method does not provide short-circuit. If either predicate returns an exceptionally completed promise, the combined asynchronous predicate also returns an exceptionally completed promise

Parameters:

predicates - a collection of AsyncPredicates that will be logically ORed

Returns:

a composed AsyncPredicate that represents a logical OR of asynchronous predicates in a given collection

or

public static <T> AsyncPredicate<T> or()

Returns:

an AsyncPredicate that always returns promise of false

See Also:

• or(Collection)

or

public static <T> AsyncPredicate<T> or(AsyncPredicate<? super T> predicate1)

Returns a given asynchronous predicate

A shortcut for or(AsyncPredicate[])

See Also:

• or(Collection)
• or(AsyncPredicate[])

or

public static <T> AsyncPredicate<T> or(AsyncPredicate<? super T> predicate1,
 AsyncPredicate<? super T> predicate2)

An optimization for or(AsyncPredicate[])

See Also:

• or(Collection)
• or(AsyncPredicate[])

or

@SafeVarargs
public static <T> AsyncPredicate<T> or(AsyncPredicate<? super T>... predicates)

Returns a composed AsyncPredicate that represents a logical OR of all predicates in a given array
