Method Summary

long	getAndStoreUniqueThreadLocalTraceId() This method returns a thread-local traceid which is globally unique and stored it local for the thread.
long	getUniqueTraceId() This methods returns a globally unique trace id.
int	incrementAndRecallThreadLocalEOI() Since this method accesses a ThreadLocal variable, it is not (necessary to be) thread-safe.
int	recallAndIncrementThreadLocalESS() Since this method accesses a ThreadLocal variable, it is not (necessary to be) thread-safe.
int	recallThreadLocalEOI() This method returns the thread-local curEoi previously registered using the method registerTraceId(curTraceId).
int	recallThreadLocalESS() This method returns the thread-local curEss previously registered using the method registerTraceId(curTraceId).
long	recallThreadLocalTraceId() This method returns the thread-local traceid previously registered using the method registerTraceId(curTraceId).
void	storeThreadLocalEOI(int eoi) Used to explicitly register an curEoi.
void	storeThreadLocalESS(int ess) Used to explicitly register a execution stack size (ess) value.
void	storeThreadLocalTraceId(long traceId) This method stores a thread-local curTraceId.
void	unsetThreadLocalEOI() This method unsets a previously registered traceid.
void	unsetThreadLocalESS() This method unsets a previously registered curEss.
void	unsetThreadLocalTraceId() This method unsets a previously registered traceid.
static ControlFlowRegistry	valueOf(String name) Returns the enum constant of this type with the specified name.

The singleton instance.

Method Detail

values

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

Returns:

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

valueOf

public static ControlFlowRegistry 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

getUniqueTraceId

public final long getUniqueTraceId()

This methods returns a globally unique trace id.

Returns:

a globally unique trace id.

getAndStoreUniqueThreadLocalTraceId

public final long getAndStoreUniqueThreadLocalTraceId()

This method returns a thread-local traceid which is globally unique and stored it local for the thread. The thread is responsible for invalidating the stored curTraceId using the method unsetThreadLocalTraceId()!

Returns:

A unique trace ID.

storeThreadLocalTraceId

public final void storeThreadLocalTraceId(long traceId)

This method stores a thread-local curTraceId. The thread is responsible for invalidating the stored curTraceId using the method unsetThreadLocalTraceId()!

Parameters:

traceId - The trace ID to store in a thread-local way.

recallThreadLocalTraceId

public final long recallThreadLocalTraceId()

This method returns the thread-local traceid previously registered using the method registerTraceId(curTraceId).

Returns:

the traceid. -1 if no curTraceId has been registered for this thread.

unsetThreadLocalTraceId

public final void unsetThreadLocalTraceId()

This method unsets a previously registered traceid.

storeThreadLocalEOI

public final void storeThreadLocalEOI(int eoi)

Used to explicitly register an curEoi. The thread is responsible for invalidating the stored curTraceId using the method unsetThreadLocalEOI()!

Parameters:

eoi - The execution order index to register.

incrementAndRecallThreadLocalEOI

public final int incrementAndRecallThreadLocalEOI()

Since this method accesses a ThreadLocal variable, it is not (necessary to be) thread-safe.

Returns:

Increments the thread local execution order index and returns it.

recallThreadLocalEOI

public final int recallThreadLocalEOI()

This method returns the thread-local curEoi previously registered using the method registerTraceId(curTraceId).

Returns:

the sessionid. -1 if no curEoi registered.

unsetThreadLocalEOI

public final void unsetThreadLocalEOI()

This method unsets a previously registered traceid.

storeThreadLocalESS

public final void storeThreadLocalESS(int ess)

Used to explicitly register a execution stack size (ess) value. The thread is responsible for invalidating the stored value using the method unsetThreadLocalESS()!

Parameters:

ess - The execution stack size to store.

recallAndIncrementThreadLocalESS

public final int recallAndIncrementThreadLocalESS()

Since this method accesses a ThreadLocal variable, it is not (necessary to be) thread-safe.

Returns:

The current execution stack size, before the incrementation.

recallThreadLocalESS

public final int recallThreadLocalESS()

This method returns the thread-local curEss previously registered using the method registerTraceId(curTraceId).

Returns:

the sessionid. -1 if no curEss registered.

unsetThreadLocalESS

public final void unsetThreadLocalESS()

This method unsets a previously registered curEss.
