Enum Constant Detail

IGNORE

public static final TracingPolicy IGNORE

Do not propagate a trace, this is equivalent of disabling tracing.

PROPAGATE

public static final TracingPolicy PROPAGATE

Propagate an existing trace.

ALWAYS

public static final TracingPolicy ALWAYS

Reuse an existing trace or create a new trace when no one exist.

Method Detail

values

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

Returns:

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

valueOf

public static TracingPolicy 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
