Detailed Description

RWTraceManager is the handle for the singleton trace event manager implementation, which accepts and forwards trace information to the connected client.

An exception is thrown if one attempts to add a client when there is one present already.

If there is no client connected, the manager buffers events. The maximum number of buffered events defaults to 100. If the maximum number of buffered events is reached, the oldest event is removed from the buffer to make room for the newest one.

The environment variable RW_TRACE_BUFFER_SIZE can be used to specify the buffer's size. Once a client is connected, the manager immediately forwards all buffered trace events, and buffering ceases. Buffering resumes when the client is disconnected.

The environment variable RW_TRACE_LEVEL can be used to specify the minimum severity level for event generation. The default severity level is INFO. The environment variable can be set to one of the following: FATAL, ERROR, WARNING, INFO, TEST, DEBUG, ENTRY, NONE.

The singleton trace event manager implementation is reference-counted, to ensure that it will not be destroyed while a client is still connected to it.

Constructor & Destructor Documentation

RWTraceManager::RWTraceManager

(

void

)

Default constructor. Always returns a handle whose body is the singleton trace event manager implementation.

RWTraceManager::RWTraceManager

(

RWStaticCtor

)

Constructs a global static handle instance (may be used before being constructed).

RWTraceManager::RWTraceManager

(

const RWTraceManager &

second

)

Attaches to and increments the reference count on second 's body.

RWTraceManager::~RWTraceManager

(

void

)

Destructor.

Member Function Documentation

static void RWTraceManager::disconnectClient

(

void

)

[static]

Tells the client (or filter) connected to the trace manager singleton to disconnect itself.

Reimplemented from RWTraceSingleClientFilter.

RWTraceEventSeverity RWTraceManager::getTraceLevel

(

)

const [inline]

Deprecated:

deprecated and no longer supported. Please use base class getLevel().

Returns the trace manager's runtime severity level.

static RWTraceManager RWTraceManager::instance

(

void

)

[static]

Static method that returns a handle to the manager. Initialization is performed, if not done already. This includes setting the maximum buffer size if RW_TRACE_BUFFER_SIZE has a positive numeric value.

void RWTraceManager::setTraceLevel

(

RWTraceEventSeverity

level

)

[inline]

Deprecated:

deprecated and no longer supported. Please use base class setLevel().

Sets the trace manager's runtime severity level.
