Enum Tracer

java.lang.Object

java.lang.Enum<Tracer>

org.lsst.ccs.description.Tracer

All Implemented Interfaces:

Serializable, Comparable<Tracer>

public enum Tracer
extends Enum<Tracer>

used to trace execution of gru. Many errors when writing a test or a node tree are just fairly hard to find: use the tracer to understand what is wrong in the interpretation of your code.

Gru internal code should use Tracer.trace at critical points.

Gru users should set a property (or environment variable) with name 'gruth.traces' the value is a comma separated list of Tracer values.

Method Detail

values

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

Returns:

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

valueOf

public static Tracer 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
