IPAddress

class IPAddress extends AnyRef

Represents an IP address. This class is similar to java.net.InetAddress, but it's designed to be more intuitive and easier to use from Scala. This package provides implicit converters to make this class compatible with java.net.InetAddress. The converters ensure that all the (non-static) methods defined in the java.net.InetAddress class are directly callable from an instance of the Scala IPAddress class. For instance, the following code is perfectly legal:

val ip = IPAddress(192, 168, 2, 5)

// Test if the address is reachable within 1 second.
println(ip + " is reachable? " + ip.isReachable(1000))

// Get the canonical host name for (i.e., do a reverse lookup on) the
// address.
println(ip + " -> " + ip.getCanonicalHostName)

// Determine whether it's the loopback address.
println(ip + " == loopback? " + ip.isLoopbackAddress)

Here's an IPv6 example:

val ip = IPAddress("fe80::21d:9ff:fea7:53e3")

// Test if the address is reachable within 1 second.
println(ip + " is reachable? " + ip.isReachable(1000))

// Get the canonical host name for (i.e., do a reverse lookup on) the
// address.
println(ip + " -> " + ip.getCanonicalHostName)

// Determine whether it's the loopback address.
println(ip + " == loopback? " + ip.isLoopbackAddress)

  9. def asInstanceOf [T0] : T0

    This method is used to cast the receiver object to be of type T0.

    This method is used to cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expressionList(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

    returns

    the receiver object.

  10. def clone () : AnyRef

  11. def eq (arg0: AnyRef) : Boolean

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on non-null instances of AnyRef: * It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true. * It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and only if y.eq(x) returns true. * It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.

    Additionally, the eq method has three other properties. * It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false. * For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false. * null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    arg0

    the object to compare against this object for reference equality.

    returns

    true if the argument is a reference to the receiver object; false otherwise.

    This method is used to test whether the dynamic type of the receiver object is T0.

    Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.
