Enum TraceLevel

java.lang.Object

java.lang.Enum<TraceLevel>

org.multiverse.api.TraceLevel

All Implemented Interfaces:

Serializable, Comparable<TraceLevel>

public enum TraceLevel
extends Enum<TraceLevel>

Using the TraceLevel you get some feedback on what is happening inside a transaction.

For tracing to work, you need to look at MultiverseConstants.TRACING_ENABLED. If not enabled, the JIT will remove dead code because we don't want any overhead.

Method Detail

values

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

Returns:

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

valueOf

public static TraceLevel 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

isLoggableFrom

public boolean isLoggableFrom(TraceLevel level)

Checks if the provided level is higher than this TraceLevel.

Parameters:

level - the TraceLevel to check

Returns:

true if level is higher or equal than this TraceLevel.

Throws:

NullPointerException - if level is null.
