Enum Constant Summary

Enum Constants

Enum Constant and Description
DIRECT Signifies that this is a direct single-segment link.
EDGE Signifies that this link is an edge, i.e.
INDIRECT Signifies that this link is potentially comprised from multiple underlying segments or hops, and as such should be used to tag links traversing optical paths, tunnels or intervening 'dark' switches.
OPTICAL Signifies that this link is realized by fiber (either single channel or WDM).
TUNNEL Signifies that this link represents a logical link backed by some form of a tunnel, e.g., GRE, MPLS, ODUk, OCH.
VIRTUAL Signifies that this link is a virtual link or a pseudo-wire.

Method Summary

Modifier and Type	Method and Description
static Link.Type	valueOf(String name) Returns the enum constant of this type with the specified name.
static Link.Type[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

DIRECT

public static final Link.Type DIRECT

Signifies that this is a direct single-segment link.

INDIRECT

public static final Link.Type INDIRECT

Signifies that this link is potentially comprised from multiple underlying segments or hops, and as such should be used to tag links traversing optical paths, tunnels or intervening 'dark' switches.

EDGE

public static final Link.Type EDGE

Signifies that this link is an edge, i.e. host link.

TUNNEL

public static final Link.Type TUNNEL

Signifies that this link represents a logical link backed by some form of a tunnel, e.g., GRE, MPLS, ODUk, OCH.

OPTICAL

public static final Link.Type OPTICAL

Signifies that this link is realized by fiber (either single channel or WDM).

VIRTUAL

public static final Link.Type VIRTUAL

Signifies that this link is a virtual link or a pseudo-wire.

Method Detail

values

public static Link.Type[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Link.Type c : Link.Type.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Link.Type valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
