Enum Constant Detail

INSTANCE

public static final TraceRegistry INSTANCE
The singleton instance.

Method Detail

values

public static final TraceRegistry[] values()
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:
for(TraceRegistry c : TraceRegistry.values())
        System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they're declared

valueOf

public static TraceRegistry 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

getTrace

public final TraceMetadata getTrace()
Gets a Trace for the current thread. If no trace is active, null is returned.

Returns:
Trace object or null

registerTrace

public final TraceMetadata registerTrace()
This creates a new unique Trace object and registers it.

Returns:
Trace object

unregisterTrace

public final void unregisterTrace()
Unregisters the current Trace object. Future calls of getTrace() will either return null or the enclosing trace object.


setParentTraceId

public final void setParentTraceId(Thread t,
                                   long traceId,
                                   int orderId)
Sets the parent for the next created trace inside this thread. This method should be used by probes in connection with SpliEvents.

Parameters:
t - the thread the new trace belongs to
traceId - the parent trace id
orderId - the parent order id
