Constructor & Destructor Documentation

trace_event_cache()

xtd::diagnostics::trace_event_cache::trace_event_cache ( )

default

Initializes a new instance of the trace_event_cache class.

Member Function Documentation

call_stack()

xtd::ustring xtd::diagnostics::trace_event_cache::call_stack

(

)

const

Gets the call stack for the current thread.

Returns

string A string containing stack trace information. This value can be an empty string ("").

Remarks

The Callstack property gets the call stack from the StackTrace property of the Environment class. The property value lists method calls in reverse chronological order. That is, the most recent method call is described first. One line of stack trace information is listed for each method call on the stack. For more information, see StackTrace.

Uncomment when stack_trace will implemented

date_time()

clock::time_point xtd::diagnostics::trace_event_cache::date_time

(

)

const

Gets the date and time at which the event trace occurred.

Returns

DateTime A DateTime structure whose value is a date and time expressed in Coordinated Universal Time (UTC).

Remarks

The first time the property is accessed in an instance of the trace_event_cache class, the current time is returned. Subsequent queries of this property in that instance return that same DateTime value, allowing it to be used as a timestamp.

logical_operation_stack()

std::vector< xtd::ustring > xtd::diagnostics::trace_event_cache::logical_operation_stack

(

)

const

Gets the correlation data, contained in a stack.

Returns

A Stack containing correlation data.

Remarks

The correlation data is stored as an object in the call context with the name "System.Diagnostics.Trace.CorrelationManagerSlot". The CorrelationManager class provides methods used to store a logical operation identity in a thread-bound context and automatically tag each trace event generated by the thread with the stored identity. The CorrelationManager is accessed through the Trace.CorrelationManager property. Each call to the StartLogicalOperation method pushes a new logical operation identity onto the stack. Each call to the StopLogicalOperation method pops a logical operation identity from the stack

process_id()

int32_t xtd::diagnostics::trace_event_cache::process_id

(

)

const

Gets the unique identifier of the current process.

Returns

int32 The system-generated unique identifier of the current process.

Remarks

Until the process terminates, the process identifier uniquely identifies the process throughout the system.

thread_id()

xtd::ustring xtd::diagnostics::trace_event_cache::thread_id

(

)

const

Gets a unique identifier for the current managed thread.

Returns

string A string that represents a unique integer identifier for this managed thread.

Remarks

The thread identifier is the value of the Thread.ManagedThreadId property formatted as a string.

timestamp()

int64_t xtd::diagnostics::trace_event_cache::timestamp

(

)

const

Gets the current number of ticks in the timer mechanism.

Returns

int64 The tick counter value of the underlying timer mechanism.

Remarks

The get accessor calls the Stopwatch.GetTimestamp method to get the timestamp. If the Stopwatch class uses a high-resolution performance counter, GetTimestamp returns the current value of that counter. If the Stopwatch class uses the system timer, GetTimestamp returns the Ticks property of DateTime.Now.
