Interface_STAT Class Reference

This class manages statistics to be queried asynchronously. Way of use : An operator describes a STAT form then fills it according to its progression. This produces a state of advancement of the process. This state can then be queried asynchronously : typically it is summarised as a percentage. There are also an identification of the current state, and informations on processed volume. More...

Detailed Description

This class manages statistics to be queried asynchronously. Way of use : An operator describes a STAT form then fills it according to its progression. This produces a state of advancement of the process. This state can then be queried asynchronously : typically it is summarised as a percentage. There are also an identification of the current state, and informations on processed volume.

A STAT form can be described once for all (as static). It describes the stream of the process (see later), in terms of phases, cycles, steps, with estimated weights. But it brings no current data.

One STAT at a time is active for filling and querying. It is used to control phasing, weighting ... Specific data for execution are given when running on active STAT : counts of items ... Data for query are then recorded and can be accessed at any time, asynchronously.

A STAT is organised as follows :

Hence, when defining the STAT form, the phases have to be described. If no weight is precisely known, give 1. for all... No phase description will give only one "default" phase For each phase, a typical cycle can be described by its steps. Here too, for no weight precisely known, give 1. for all...

For executing, activate a STAT to begin count. Give counts of items and cycles for the first phase (for the unique default one if no phasing is described) Else, give count of items and cycles for each new phase. Class methods allow also to set next cycle (given count of items), next step in cycle (if more then one), next item in step.

Constructor & Destructor Documentation

Interface_STAT::Interface_STAT ( const Standard_CString  title = "")

Creates a STAT form. At start, one default phase is defined, with one default step. Then, it suffises to start with a count of items (and cycles if several) then record items, to have a queryable report.

Interface_STAT::Interface_STAT ( const Interface_STAT other)

used when starting

Member Function Documentation

void Interface_STAT::AddPhase ( const Standard_Real  weight,
const Standard_CString  name = "" 
)

Adds a new phase to the description. The first one after Create replaces the default unique one.

void Interface_STAT::AddStep ( const Standard_Real  weight = 1)

Adds a new step for the last added phase, the default unique one if no AddPhase has already been added Warning : AddStep before the first AddPhase are cancelled.

void Interface_STAT::Description ( Standard_Integer nbphases,
Standard_Real total,
Standard_CString title 
) const

Returns global description (cumulated weights of all phases, count of phases,1 for default, and title)

static void Interface_STAT::End ( )
static

Commands to declare the process ended (hence, advancement is forced to 100 %)

void Interface_STAT::Internals ( Handle< TCollection_HAsciiString > &  tit,

static void Interface_STAT::NextCycle ( const Standard_Integer  items)
static

Commands to resume the preceeding cycle and start a new one, with a count of items Ignored if count of cycles is already passed Then, first step is started (or default one) NextItem can be called for the first step, or NextStep to pass to the next one.

static void Interface_STAT::NextItem ( const Standard_Integer  nbitems = 1)

static void Interface_STAT::NextPhase ( const Standard_Integer  items,
const Standard_Integer  cycles = 1 
)
static

Commands to resume the preceeding phase and start a new one <items> and <cycles> as for Start, but for this new phase Ignored if count of phases is already passed If <cycles> is more than one, the first Cycle must then be started by NextCycle (NextStep/NextItem are ignored). If it is one, NextItem/NextStep can then be called.

static void Interface_STAT::NextStep ( )
static

static Standard_Integer Interface_STAT::Percent ( const Standard_Boolean  phase = Standard_False)
static

Returns the advancement as a percentage : <phase> True : inside the current phase <phase> False (D) : relative to the whole process.

void Interface_STAT::Phase ( const Standard_Integer  num,
Standard_Integer n0step,
Standard_Integer nbstep,
Standard_Real weight,
Standard_CString name

Returns description of a phase, given its rank (n0 for first step, count of steps, default gives one; weight, name)

static void Interface_STAT::SetPhase ( const Standard_Integer  items,
const Standard_Integer  cycles = 1

static

Changes the parameters of the phase to start To be used before first counting (i.e. just after NextPhase) Can be used by an operator which has to reajust counts on run.

void Interface_STAT::Start ( const Standard_Integer  items,
const Standard_Integer  cycles = 1 
) const

Starts a STAT on its first phase (or its default one) <items> gives the total count of items, <cycles> the count of cycles If <cycles> is more than one, the first Cycle must then be started by NextCycle (NextStep/NextItem are ignored). If it is one, NextItem/NextStep can then be called.

static void Interface_STAT::StartCount ( const Standard_Integer  items,
const Standard_CString  title = "" 
)
static

Starts a default STAT, with no phase, no step, ready to just count items. <items> gives the total count of items Hence, NextItem is available to directly count.

Standard_Real Interface_STAT::Step ( const Standard_Integer  num) const

Returns weight of a Step, related to the cumul given for the phase. <num> is given by <n0step> + i, i between 1 and <nbsteps> (default gives n0step < 0 then weight is one)

static Standard_CString Interface_STAT::Where ( const Standard_Boolean  phase = Standard_True)
