Enum Constant Detail

SERVER

public static final Span.Kind SERVER

Indicates that the span covers server-side handling of an RPC or other remote request.

CLIENT

public static final Span.Kind CLIENT

Indicates that the span covers the client-side wrapper around an RPC or other remote request.

PRODUCER

public static final Span.Kind PRODUCER

Indicates that the span describes producer sending a message to a broker. Unlike client and server, there is no direct critical path latency relationship between producer and consumer spans.

CONSUMER

Indicates that the span describes consumer receiving a message from a broker. Unlike client and server, there is no direct critical path latency relationship between producer and consumer spans.

Method Detail

values

public static Span.Kind[] 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 (Span.Kind c : Span.Kind.values())
    System.out.println(c);

Returns:

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

valueOf

public static Span.Kind 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
