FlexScriptクラス - TrackedVariable

TrackedVariable

Description

A class that represents a tracked variable.

Tracked Variables can be defined as global for the model, or they can be stored on an object, table or label.

Properties

average Gets the average value of the tracked variable.
count Gets the number of times the tracked variable has been set.
history Gets the table of profiles for the tracked variable.
lowerBound Gets or sets the lower bound of the tracked variable.
maximum Gets the maximum value of the tracked variable.
minimum Gets the minimum value of the tracked variable.
profile Gets the table of profiles for the tracked variable.
rate Gets or sets the current rate of the tracked variable.
type Gets the type of the tracked variable.
upperBound Gets or sets the upper bound of the tracked variable.
value Gets or sets the current value of the tracked variable.
valueString Gets or sets the current value of the categorical tracked variable.

Methods

getCategoryName Gets the name of a category from a categorical tracked variable.
getTotalTimeAt Gets the total time the tracked variable as been at the specified categorical value.
reset Resets the tracked variable.

Constructor

init Asserts tracked variable data on a node with the designated type and start value.
TrackedVariable Creates a reference to a global tracked variable.

Static Methods

init Asserts tracked variable data on a node with the designated type and start value.

TrackedVariable.average

readonly double average

Description

Gets the average value of the tracked variable.

The average value is not available for Categorical and Cumulative type tracked variables. See the type property for more information. double average = trackedVariable.average;

TrackedVariable.history

readonly Table history

Description

Gets the table of profiles for the tracked variable.

The history property is only available if the tracked variable flags is set to STAT_USE_HISTORY. See the init method for information on tracked variable flags. 

Table history = trackedVariable.history;
double time = history[1][1];
double value = history[1][2];
double rate = history[1][3]; //Kinetic type

TrackedVariable.lowerBound

double lowerBound

Description

Gets or sets the lower bound of the tracked variable.

The lowerBound property is only available for Kinetic type tracked variables. When setting the lower bound, the lower bound must be less than the current value of the tracked variable. 

double lower = trackedVariable.lowerBound;
trackedVariable.lowerBound = -100;

Description

Gets the maximum value of the tracked variable.

double maximum = trackedVariable.maximum;

TrackedVariable.minimum

readonly double minimum

Description

Gets the minimum value of the tracked variable.

double minimum = trackedVariable.minimum;

TrackedVariable.profile

readonly Table profile

Description

Gets the table of profiles for the tracked variable.

The profile property is only available for Categorical type tracked variables. 

Table profile = trackedVariable.profile;
string name = profile[2][1];
double value = profile[2][2];

TrackedVariable.rate

double rate

Description

Gets or sets the current rate of the tracked variable.

The rate property is only available for Kinetic type tracked variables. See the type property for more information. 

double rate = trackedVariable.rate;
trackedVariable.rate = 1.5;

TrackedVariable.type

readonly int type

Description

Gets the type of the tracked variable.

The type affects what meta data, like average, will be collected, and how it is calculated. Type can be one of the following values:
STAT_TYPE_LEVEL - records the variable as a level that can go up and down, such as content. The average is a time-weighted average. An example of this would be content tracking.
STAT_TYPE_TIME_SERIES - records the variable as a series of independent values. The average is a non-time-weighted average. An example of this type is staytime tracking.
STAT_TYPE_CUMULATIVE - records the variable as a value that only accumulates over time, such as input or output. Average is not tracked.
STAT_TYPE_CATEGORICAL - records the variable as a set of values, where values do not have a mathematical relationship to each other. Average is not tracked. An example of this is state tracking.
STAT_TYPE_KINETIC_LEVEL - similar to STAT_TYPE_LEVEL, except that you can also give it a rate of change by setting the rate property. An example of this would be battery level. int type = trackedVariable.type;

TrackedVariable.upperBound

double upperBound

Description

Gets or sets the upper bound of the tracked variable.

The upperBound property is only available for Kinetic type tracked variables. When setting the upper bound, the upper bound must be greater than the current value of the tracked variable. 

double upper = trackedVariable.upperBound;
trackedVariable.upperBound = 100;

TrackedVariable.value

Variant value

Description

Gets or sets the current value of the tracked variable.

The value of the tracked variable should be a number or it may be a string for categorical type tracked variables. 

double value = trackedVariable.value;
trackedVariable.value = 32;
trackedVariable.value = "processing"; //Categorical type only

TrackedVariable.valueString

Variant valueString

Description

Gets or sets the current value of the categorical tracked variable.

The valueString is only available for the categorical type tracked variables. 

string valueStr = trackedVariable.valueString;
trackedVariable.valueString = "processing";

TrackedVariable.getCategoryName()

string getCategoryName( int catNum )

Parameters

catNum The category number to get the name of.

Description

Gets the name of a category from a categorical tracked variable.

string name = trackedVariable.getCategoryName(1);

TrackedVariable.getTotalTimeAt()

double getTotalTimeAt( Variant value )

Parameters

value Value should be either the name of the category value to get, or the index number of the category.

Description

Gets the total time the tracked variable as been at the specified categorical value.

The getTotalTimeAt method is only available for Categorical type tracked variables. 

double processingTime = trackedVariable.getTotalTimeAt("processing");
double processingTime = trackedVariable.getTotalTimeAt(2);

TrackedVariable.reset()

reset( double startValue = 0.0 , int type = -1 )

Parameters

startValue The start value of the tracked variable.
type If no value is defined, the tracked variable will keep its original type. See the type property for more information.

Description

Resets the tracked variable.


trackedVariable.reset();
trackedVariable.reset(10);
trackedVariable.reset(0, STAT_TYPE_LEVEL);

TrackedVariable Constructor

static init( treenode theNode , int type , double startValue = 0 , int flags = -1 )

Parameters

theNode The node to assert the tracked variable data on.
type Defines the tracked variable type. See the type property for more information.
startValue The starting value of the tracked variable. If the tracked variable presists when the model is reset, this will be the reset value.
flags Specifies options for this tracked variable. The flags can be a bitwise combination of the following three values. By default, none of these options are used:
STAT_USE_HISTORY - the tracked variable will keep a history of each value it hold, and the time at which the value is set.
STAT_USE_PROFILE - the tracked variable will track a profile of the total time spent at each value. This only works if the set of used values are non-negative integers.
STAT_IGNORE_WARMUP - the tracked variable will ignore the resetstats() command. Use this option only if the tracked variable should keep the data collected during warmup time.

Description

Asserts tracked variable data on a node with the designated type and start value.

TrackedVariable newTV = TrackedVariable.init(aNode, STAT_TYPE_TIME_SERIES, 0.0, STAT_USE_HISTORY | STAT_IGNORE_WARMUP);

TrackedVariable Constructor

TrackedVariable( string name )

Parameters

name The name of the global tracked variable.

Description

Creates a reference to a global tracked variable.

TrackedVariable wip = TrackedVariable("WorkInProgress");

Description

Asserts tracked variable data on a node with the designated type and start value.
