Data Objects

Device Application Designer provides layers for wrapping data, such as styles, variables, and mobile business objects (MBOs).

Device Application Designer Data Object Types
Data Type	Class	Description
Variable	ControlVariable	Holds the variable attributes for controls. It includes type (USER for user-defined variables, SYSTEM for system-defined variables, TABLE for table context variables), key (variable key), and MBO id (for table context variables).
Variable Management	RIMVariables	Manages variables, including store/access variables.
Style	FontStyle	Holds the font information, including font face, font size, font size unit, font style, background color, foreground color, and gradient color.
Logical Type	LogicalType	Contains all the logical type information. Also contains personal information management (PIM) information if applicable.
MBO	CommonMBOModel MBOModel PKMBOModel	CommonMBOModel contains information about MBOs and their subclasses, including normal MBO, personalization MBO, and local business object. CommonMBOModel provides methods for the MBO, including submitPendingOperations and syncPublication. Other important classes in this package include: ModelChangeEvent MobileApplicationDataHandler MobileApplicationDataPagingHandler MBOModelSyncParameters
MBO Attribute	MBOAttribute	Contains information about MBO attribute ID, display name and datatype.
Client Profile	RIMClientProfile	Contains client profile information, including profile name, server name, server port, user name, password, package name, stream parameters, and so on.
Link Parameter	RIMLinkParamNode	Contains link parameter information.
MBO Application	RIMMBOMobileApplication	Represents the MBO in Device Application Designer styles.
Repository	RIMRepository	The central place for store or accessing the client profile, client settings, variables, MBO applications, and other settings.
Settings	RIMSettings	Contains various settings information, including the push settings, screen saver settings, log level settings.
Validation Object	RIMValidationObject	Manages validation information, including regular expressions and messages.

Example 1

These examples illustrate how to assign and read variables.

Adds a variable in BOBCUIdefinition:

addVariable(VARIABLE_HISVAR, "hisVarValue",
	VariableProperties.VARIABLE_TYPE_USER,
	MBOAttribute.SCHEMA_TYPE_STRING);

Use variables in controls:

case LABEL2:
Label locallabel2 = (Label) object;
locallabel2.setFontStyle(styleLabel_Style);
//locallabel2.setFooterField(null);
locallabel2.setFocusFontStyle(styleDefault_Style);
locallabel2.setWrapText(false);
locallabel2.setVariableLabel(new ControlVariable(
		BOBCUIDefinition.VARIABLE_HISVAR,
		VariableProperties.VARIABLE_TYPE_USER, null, null));

Use table variables:

localtextInput4.setVariableInput(new ControlVariable(
		"dept_head_id", VariableProperties.VARIABLE_TYPE_TABLE,
		BOBCUIDefinition.MBO_A_B_C_DEPARTMENT, null));

Context variables must be saved before table variables are used by context actions:

case MENU6:
MenuAction menu6 = (MenuAction) object;
//Create list of actions 
ActionList actionList13 = new ActionList();
IBOBAction connectionAction9 = new ScreenAction(UIDefinition
		.getScreen("screen4"), false, null);
menu6.setAction(actionList13);
IBOBAction contextAction4 = new SaveMobileDataContextAction(
		cellTable1);
actionList13.addAction(contextAction4);
actionList13.addAction(connectionAction9);
cellTable1.setDefaultAction(actionList13);
