Value members

Concrete methods

def asScala[A](i: Iterator[A]): Iterator[A]

Converts a Java Iterator to a Scala Iterator.

Converts a Java Iterator to a Scala Iterator.

The returned Scala Iterator is backed by the provided Java Iterator and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Iterator was previously obtained from an implicit or explicit call of asJava then the original Scala Iterator will be returned.

Value Params
i

The Java Iterator to be converted.

Returns

A Scala Iterator view of the argument.

def asScala[A](e: Enumeration[A]): Iterator[A]

Converts a Java Enumeration to a Scala Iterator.

Converts a Java Enumeration to a Scala Iterator.

The returned Scala Iterator is backed by the provided Java Enumeration and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Enumeration was previously obtained from an implicit or explicit call of asJavaEnumeration then the original Scala Iterator will be returned.

Value Params
e

The Java Enumeration to be converted.

Returns

A Scala Iterator view of the argument.

def asScala[A](i: Iterable[A]): Iterable[A]

Converts a Java Iterable to a Scala Iterable.

Converts a Java Iterable to a Scala Iterable.

The returned Scala Iterable is backed by the provided Java Iterable and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Iterable was previously obtained from an implicit or explicit call of asJava then the original Scala Iterable will be returned.

Value Params
i

The Java Iterable to be converted.

Returns

A Scala Iterable view of the argument.

def asScala[A](c: Collection[A]): Iterable[A]

Converts a Java Collection to a Scala Iterable.

Converts a Java Collection to a Scala Iterable.

If the Java Collection was previously obtained from an implicit or explicit call of asJavaCollection then the original Scala Iterable will be returned.

Value Params
c

The Java Collection to be converted.

Returns

A Scala Iterable view of the argument.

def asScala[A](l: List[A]): Buffer[A]

Converts a Java List to a Scala mutable Buffer.

Converts a Java List to a Scala mutable Buffer.

The returned Scala Buffer is backed by the provided Java List and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java List was previously obtained from an implicit or explicit call of asJava then the original Scala Buffer will be returned.

Value Params
l

The Java List to be converted.

Returns

A Scala mutable Buffer view of the argument.

def asScala[A](s: Set[A]): Set[A]

Converts a Java Set to a Scala mutable Set.

Converts a Java Set to a Scala mutable Set.

The returned Scala Set is backed by the provided Java Set and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Set was previously obtained from an implicit or explicit call of asJava then the original Scala Set will be returned.

Value Params
s

The Java Set to be converted.

Returns

A Scala mutable Set view of the argument.

def asScala[A, B](m: Map[A, B]): Map[A, B]

Converts a Java Map to a Scala mutable Map.

Converts a Java Map to a Scala mutable Map.

The returned Scala Map is backed by the provided Java Map and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Map was previously obtained from an implicit or explicit call of asJava then the original Scala Map will be returned.

If the wrapped map is synchronized (e.g. from java.util.Collections.synchronizedMap), it is your responsibility to wrap all non-atomic operations with underlying.synchronized. This includes get, as java.util.Map's API does not allow for an atomic get when null values may be present.

Value Params
m

The Java Map to be converted.

Returns

A Scala mutable Map view of the argument.

def asScala[A, B](m: ConcurrentMap[A, B]): Map[A, B]

Converts a Java ConcurrentMap to a Scala mutable ConcurrentMap.

Converts a Java ConcurrentMap to a Scala mutable ConcurrentMap.

The returned Scala ConcurrentMap is backed by the provided Java ConcurrentMap and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java ConcurrentMap was previously obtained from an implicit or explicit call of asJava then the original Scala ConcurrentMap will be returned.

Value Params
m

The Java ConcurrentMap to be converted.

Returns

A Scala mutable ConcurrentMap view of the argument.

def asScala[A, B](d: Dictionary[A, B]): Map[A, B]

Converts a Java Dictionary to a Scala mutable Map.

Converts a Java Dictionary to a Scala mutable Map.

The returned Scala Map is backed by the provided Java Dictionary and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

If the Java Dictionary was previously obtained from an implicit or explicit call of asJavaDictionary then the original Scala Map will be returned.

Value Params
d

The Java Dictionary to be converted.

Returns

A Scala mutable Map view of the argument.

def asScala(p: Properties): Map[String, String]

Converts a Java Properties to a Scala mutable Map[String, String].

Converts a Java Properties to a Scala mutable Map[String, String].

The returned Scala Map[String, String] is backed by the provided Java Properties and any side-effects of using it via the Scala interface will be visible via the Java interface and vice versa.

Value Params
p

The Java Properties to be converted.

Returns

A Scala mutable Map[String, String] view of the argument.
