Class: DaySchedule

PD. DaySchedule

Defines a series of temporal values for a single day.

Day schedules store a series of values at periodic time increments over a single 24hr day. The default is to store 24 hourly values, but you can use any time increment that evenly divides into 24hrs, limited to between 1 minute (1440 values) and 6 hours (4 values).

Day schedules are used by PD.Schedule instances and are assigned to one or more days of the year to provide a detailed map of how a value changes throughout the year.

To make day schedules as flexible as possible, they are always stored as fractional values in the range 0 to 1. This allows them to be used for pretty well any purpose and easily mapped to any other value range or unit types defined by their host schedule. The display and editor UI components usually reflect the values as mapped to the schedule value range, however they are always stored internally as fractions.

Type
:string

className <readonly>

The name of the subclass for this object instance.

This name must match the name of this class within the PD.Registry. Thus, the base implementation simply references this.constructor.getClassName() to ensure that this is always the case even for subclasses. As a result, there is rarely any need to override this method.

This property is used when copying, storing and exporting data for subclass instances to ensure that they are recreated as instances of the right class.

Type

:string

color

The color of this day schedule, given as a CSS color in the form '#RRGGBB'.

Type

:Array

data

An array of fractional data values for each time step in the day (0 to 1).

This defaults to an array of 24 hourly fractional data values.

dataAsCSV

Converts the data to/from comma-separated values.

This is provided as a getter/setter mainly to allow the data to be edited as a dynamic parameter.

iconName <readonly>

The name of the SVG icon to associate with this object instance.

This name should match the name of the icon associated with this class within the PD.Registry. Thus, the default implementation simply references this.constructor.getClassName() to ensure that this is always the case, even for subclasses. However, you can override this property if you want a different icon dependant on other properties of the class instance, as shown in the example below.

Methods

changeResolution(resolution)

Interpolates/extrapolates the profile into a different number of time steps.

A profile must have at least 1 value (which creates a flat profile over the whole day) and a maximum 1440 (which is one for each minute of the day). Time increments of less than one minute are not yet supported.

If the number of time steps is greater than 24 (one per hour) then the number of steps will be adjusted to some multiple of 24 to ensure that the values occur at the same minute in each consecutive hour. This is done to be compatible with the majority of analysis tools.

Parameters:
Name Type Description
resolution number

The new number of time steps over a 24hr day (1 to 1440).
Returns:

Returns this instance to support method chaining.

Type
PD.DaySchedule

checkDynamicParameter(param, group [, host])

Provides an opportunity to dynamically limit the value and/or range of each parameter.

This method is called whenever a dynamic parameter is interactively changed. The param argument gives access to the parameter being changed whilst the group argument gives access to other parameters within the same parameter group.

NOTE: Range validation in this method is not absolutely required, but doing so can prevent unnecessary model rebuilds due to out-of-range parameters being different from their previous values, even though the object's geometry will not actually change due to range constraints within the subclasses rebuild() method. Thus, it is usually best to do them here so that someone's future airport model is not entirely rebuilt each time they try to set a too-large length in your custom door handle component.

Parameters:
Name Type Argument Description
param PD.Parameter

The parameter that is being interactively changed.
group PD.ParamGroup

The group that the dynamic parameter belongs to.
host object <optional>

For components only, the parent or host object that called this method.
Inherited From:
Overrides:
Example
checkDynamicParameter(param, group, host) {

     switch (param.name) {

         case 'height':
             if (param.value < 1.0) param.value = 1.0;
             break;

         case 'width':
         case 'length':
             if (param.value < 100.0) param.value = 100.0;
             if (this.standardBedSize > 0) { // If not custom.
                 group.setParameterValue('standardBedSize', 0);
                 this.standardBedSize = 0; // Make it custom.
             }
             break;

         case 'standardBedSize': {
                 const std_bed = this.getStandardBedSize(Math.round(param.value));
                 if (std_bed != null) {
                     const [ width, length ] = (PD.DIMENSION.useImperial) ? std_bed.sizeImperial : std_bed.sizeMetric;
                     this.width = PD.Utils.toNumber(width, this.width);
                     group.setParameterValue('width', this.width);
                     this.length = PD.Utils.toNumber(length, this.length);
                     group.setParameterValue('length', this.length);
                 }

Computes the value for the given hour period from the profile data.

Parameters:
Name Type Description
hour number

The integer hour to compute the value for.
Returns:

Returns the value for the given hour.

Type
number

getInterpolatedValue(time_of_day)

Computes the value at the exact time of day from the profile data.

interpolateBetween( [new_data])

Interpolates/extrapolates the profile into a different number of time steps.

A profile must have at least 1 value (which creates a flat profile over the whole day) and a maximum 1440 (which is one for each minute of the day). Time increments of less than one minute are not yet supported.

Returns:

Returns the given array or a new one with the interpolated data.

Type
Array

setData(data)

Resizes the stored array to match and copies the data from the given array.

This method takes either a day schedule or an array of fractional data values for each time step across the day. The time step is calculated automatically from the number of values in the array. For an hourly profile, ensure that there are exactly 24 values in the array. For a 15min time step, ensure there are 96 values in the array (24 * (60 / 15)).

Parameters:

Returns:

Returns values as a CSV data string.

Type
string

toJSON( [data])

Converts the day schedule data to a simple POJO for JSON storage.

This method is used to copy, store and save the data for this day schedule, so the returned object must have all the properties required be able to be able to fully rebuild it when passed to the class constructor.
