Constructors

constructor

  • new ParameterBoolean(subject, name, localName, getter, setter, opt_choices?, opt_values?): ParameterBoolean

  • Parameters

    • subject: Subject

      the Subject whose value this ParameterBoolean represents

    • name: string

      the language-independent name of this Parameter; the English name can be passed in here because it will be run thru Util.toName.

    • localName: string

      the localized name of this Parameter

    • getter: (() => boolean)

      A function with no arguments that returns the value of this Parameter

        • (): boolean

        • Returns boolean

    • setter: ((v) => void)

      A function with one argument that sets the value of this Parameter

        • (v): void

        • Parameters

          • v: boolean

          Returns void

    • Optional opt_choices: string[]

      the translated localized strings corresponding to the values (optional)

    • Optional opt_values: boolean[]

      the booleans corresponding to the choices that the parameter can be set to (optional)

    Returns ParameterBoolean

Properties

Private choices_

choices_: string[] = []

the translated localized strings corresponding to the values

Private values_

values_: boolean[] = []

the booleans corresponding to the choices

Methods

getAsString

getChoices

getName

  • getName(opt_localized?): string

  • Name of this SubjectEvent, either the language-independent name for scripting purposes or the localized name for display to user.

    The language-independent name should be the same as the English version but capitalized and with spaces and dashes replaced by underscore, see Util.toName and nameEquals.

    Parameters

    • Optional opt_localized: boolean

      true means return the localized version of the name; default is false which means return the language independent name.

    Returns string

    name of this object

getSubject

getValue

getValues

  • getValues(): string[]

  • Returns the set of values corresponding to getChoices that this Parameter can be set to.

    Returns string[]

    set of values that this Parameter can be set to, in string form.

isComputed

  • isComputed(): boolean

  • Returns whether the value is being automatically computed; setting the value of this Parameter has no effect.

    Examples of automatically computed Parameters: the variables that give the current energy of a simulation. Another example is when the size of a graph's SimView is under control of an AutoScale.

    Returns boolean

    whether the value is being automatically computed

nameEquals

  • nameEquals(name): boolean

  • Whether this SubjectEvent has the given name, adjusting for the transformation to a language-independent form of the name, as is done by Util.toName.

    Parameters

    • name: string

      the English or language-independent version of the name

    Returns boolean

    whether this SubjectEvent has the given name (adjusted to language-independent form)

setChoices

  • setChoices(choices, values, opt_broadcast?): void

  • Sets the choices and values associated with this Parameter.

    Parameters

    • choices: string[]

      localized strings giving name of each choice

    • values: boolean[]

      the values corresponding to each choice

    • Optional opt_broadcast: boolean

      whether to broadcast this change to the Subject's Observers, default is true

    Returns void

    Throws

    if values is of different length than choices

setComputed

setFromString

  • setFromString(value): void

  • Sets the value of this Parameter after converting the given string to the appropriate type (boolean, number or string).

    Parameters

    • value: string

      the value to set this Parameter to, in string form

    Returns void

    Throws

    if the string cannot be converted to the needed type

setValue

  • setValue(value): void

  • Sets the value of this ParameterBoolean.

    Parameters

    • value: boolean

      the value to set this ParameterBoolean to

    Returns void

toString

toStringShort

  • toStringShort(): string

  • Returns a minimal string representation of this object, usually giving just identity information like the class name and name of the object.

    For an object whose main purpose is to represent another Printable object, it is recommended to include the result of calling toStringShort on that other object. For example, calling toStringShort() on a DisplayShape might return something like this:

    DisplayShape{polygon:Polygon{'chain3'}}

    Returns string

    a minimal string representation of this object.
