Overview

Excerpt
This class lets you inspect the current form state as well as perform actions on it, such as adding handlers or updating values.

The B25.Form class is the main point of interaction for anything that you want to do on the form. Inside the customize method (defined in the B25.Form.Customizer interface) you can add your own event handlers to the form (or its child elements). Inside the handleEvent method of your own handlers, you can inspect the current form state and update values on it (or its child elements). Use the getter methods to access lower level child elements, such as fields or related lists.

Example 1: Adding a handler

Adding handlers is done inside the customize method of your own implementation of the B25.Form.Customizer interface.

Also see: Quick Start Guide

Code Block

global with sharing class MyFormCustomizer implements B25.Form.Customizer {
    global void customize(B25.Form form) {
        form.getField(B25__Reservation__c.B25__Status__c).onUpdate(new MyStatusHandler());
    }
}

Example 2: Updating the form

Updating the form is done inside the handleEvent method of your own event handlers.

Also see: B25.FormEventHandler

Code Block

global with sharing class MyStatusHandler extends B25.FormEventHandler {
    global override void handleEvent(B25.FormEvent event, B25.Form form) {
        form.getField(B25__Reservation__c.B25__Title__c).updateValue('Hello World!');
    }
}

Interfaces

B25.Form.Customizer

The B25.Form.Customizer interface is what you need to implement to attach your own handlers to the form (also see: Quick Start Guide). It only has one method, with the following signature:

Code Block
void customize(B25.Form form)

Parameters:

Name	Type	Description
form	B25.Form	The form, to which you can add your own handlers.

Methods

getField

Code Block
B25.FieldFormField getField(SObjectField fieldToken)

This method will return a Field object for the specified SObjectField. The SObjectField must be an existing reservation field.

Parameters: SObjectField

Return value:B25.FormField

getLookup

Code Block
B25.Lookup getLookup(SObjectField fieldToken)

Similar to getField, but instead this method will return a Lookup object for the specified SObjectField. The SObjectField must be an existing lookup field on reservation.

Parameters: SObjectField

Return value:B25.Lookup

getRelatedList

Code Block
B25.RelatedList getRelatedList(SObjectType sObjectToken)

Parameters: SObjectType

Return value:B25.RelatedList

onInit (without parameters)

Code Block
List<B25.FormEventHandler> onInit()

Returns a reference to the list of handlers that have been defined to trigger when the form is initialized. Because this method returns a reference to the actual list (and not a copy), any changes you make to this list will directly affect the defined handlers. This method is intended to be used in the customize method defined in your implementation of the B25.Form.Customizable interface. Using it anywhere else, such as inside one of your event handlers, will not have any effect.

Return value: List<B25 List<B25.FormEventHandler>FormEventHandler>

onInit (with parameter)

Code Block
void onInit(B25.FormEventHandler handler)

Adds the given handler to the list of handlers that have been defined to trigger when the form is initialized. This method is a convenience method, and is identical to calling onInit().add(B25.FormEventHandler handler).
