Classes

RSDTaskObject is the interface for running a task. It includes information about how to calculate progress, validation, and the order of display for the steps.

RSDChoiceInputFieldObject is a concrete implementation of RSDChoiceInputField that subclasses RSDInputFieldObject to include a list of choices for a multiple choice or single choice input field.

RSDUIStepObject is the base class implementation for all UI display steps defined in this framework. Depending upon the available real-estate, more than one ui step may be displayed at a time. For example, on an iPad, you may choose to group a set of questions using a RSDSectionStep.

RSDInputFieldTableItemGroup is used to represent a single input field.

RSDActiveUIStepObject extends the RSDUIStepObject to include a duration and commands. This is used for the case where an RSDUIStep has an action such as start walking or stop walking; the step may also implement the RSDActiveUIStep protocol to allow for spoken instruction.

RSDTableItem can be used to represent the type of the row to display.

RSDTextTableItem is used to represent a item row that has static text.

RSDImageTableItem is used to represent a item row that has a static image.

RSDInputFieldTableItem is an abstract base class implementation for representing an answer, or part of an answer for a given RSDInputField.

RSDMultipleComponentInputFieldObject extends the properties of RSDInputFieldObject with information required to create a multiple component input field.

RSDTaskPath is used to keep track of the current state of a running task.

RSDTableItemGroup is a generic table item group object that can be used to display information in a tableview that does not have an associated input field.

RSDChoiceTableItem is used to represent a single row in a table where the user picks from a list of choices.

RSDDataLogger is used to write data samples using a custom encoding to a logging file.

RSDFileResultUtility is a utility for naming temporary files used to save task results.

RSDTextInputTableItem is used to represent a single row in a table that holds a text entry input field. Typically, this would be used to represent a single RSDInputField value, but it can also be used to represent a single component in a multiple-component field.

RSDFormUIStepObject is a concrete implementation of the RSDFormUIStep and RSDSurveyNavigationStep protocols. It is a subclass of RSDUIStepObject and can be used to display a navigable survey.

RSDFactory handles customization of decoding the elements of a task. Applications should override this factory to add custom elements required to run their task modules.

Defines a section in a table. A table is made up of sections, groups and items. For most group types, there is one cell per group. The exception would be where the ui hint is for a list where each value is displayed in a selectable list.

RSDSampleRecorder is a base-class implementation of a controller that is used to record samples.

While it isn’t prohibited to instatiate this class directly, this is intended as an abstract implementation for recording sample data from GPS location, accelerometers, etc.

Using this base implementation allows for a consistent logging of shared sample data key words for the step path and the uptime. It implements the logic for writing to a file, tracking the uptime and start date, and provides a consistent implementation for error handling.

RSDRecordSampleLogger is used to write samples encoded as json dictionary objects to a logging file.

RSDFormStepDataSourceObject is a concrete implementation of the RSDFormStepDataSource protocol.

RSDChoicePickerTableItemGroup subclasses RSDInputFieldTableItemGroup to implement a single or multiple choice question where the choices are presented as a list.

RSDResourceConfig is designed as an overridable resource configuration manager. The functions and properties are intended to be overridable in the app by implementing a custom extension of the function with the same name. This is designed to use app-wins namespace conflict resolution that is typical of obj-c architecture.

RSDUIActionHandlerObject is intended as an abstract implementation of the action handler that implements the Codable protocol.

LocalizationBundle is a wrapper for returning a bundle along with a table name and target suffixes. This is used by the Localization class to return localized strings that are defined in a strings file embedded in the given bundle.

Localization is a wrapper class for getting a localized string that allows overriding the bundles to search for a given string. To use this class, call one of the localization methods. To override the value returned by one of the bundles, add the string to a bundle higher up in the list order of the allBundles property.

An item group for entering data that is a human-measurement in localized units appropriate to the size-range of a human (adult, child, infant).

RSDInputFieldObject is a Decodable implementation of the RSDSurveyInputField protocol. This is implemented as an open class so that the decoding strategy can be used to support subclasses.
