TypeDefinition contains the prefixed information sets required to run Nexacro and Nexacro Studio. The TypeDefinition file is an actual object that is edited and utilized to run a project. You can add, delete and modify items through the TypeDefinition editors, which take the form of dialogue boxes. The TypeDefinition file is formatted in XML.

To open the pop-up TypeDefinition editors, locate the submenu of TypeDefinition in the Project Explorer first. Then, double-click each item. Otherwise, open a context menu by right-clicking each item and select [Edit].

Objects

The Objects editor manages the libraries used to run Nexacro as well as objects used in a Form.

Edit modules

You must enter a module's name, and the name should be unique. Registered module files are managed with relative paths that are determined according to the location specified at "Base Lib Path" in [Tools > Options]. If a specified module file does not exist, the editing process will be aborted with an alert message popping up.

Change order

Order matters when registering modules, which are loaded before an application. As modules are interdependent, loading a project developed by Nexacro Studio may fail if modules are not registered in the correct order. Accordingly, click the Up/Down button if you want to change the order.

View file source

Selecting a module and clicking the "Show Json" button will display the relevant file code by opening a separate window. The presented code is read-only.

List of objects

	Description
ID	This value is essential and unique.
ClassName	This value is essential and unique.
Image	The image is used as the object's icon displayed on the toolbar.
Width	These are the width and height values that will apply when you do not specify any values. That is, these values will apply when you create a component in the Form by mouse clicking rather than dragging.
Height
PrefixID	This value is used to name the ID of a created object. Object IDs consist of PrefixIDs and following double digit numbers in ascending order. (eg. [PrefixID]+"00", [PrefixID]+"01"...)

The DefaultWidth and DefaultHeight values are meaningless to invisible objects such as a Dataset.

If you enter an invalid value for the Width, Height item, it is treated as 0.

For components that can be placed on the design screen, even if you set the value of the component's Width, Height item to 0 in the TypeDefinition, when you place the component, the value of the width, height property is treated as 100 for screen design convenience.

The default list only includes the frequently-used objects. If you want to add another object, expand the object list of the ComComp, Grid or DeviceAPI module, select the object you want to add and then click the plus (+) button at the end.

Object refactoring

Nexacro Studio will automatically perform code refactoring when object IDs in TypeDefinition are changed. The tool will search the current file and automatically make proper changes in relevant object IDs.

If you change the ID of a button object from Button to Button2, Nexacro Studio will search the entire project, find all the Forms that use Button and list them. If you click the [Rename] button thereafter, the Studio will rename all the found IDs and then open the all the relevant Forms to let you determine whether to save the changes.

PrefixID

You can designate a prefix for naming an ID of each component or other object. For instance, if you designate "Btn" as the PrefixID for Button components, the ID of a Button component will begin with "Btn" (eg. "Btn00") when it is created.

Services

Access the Services tab for managing service definitions, and the folder path or Internet URL.

Use the Add and Delete button to add new services or delete selected services.

The order of items registered in the User Service can be changed by dragging and dropping the icon displayed in front of the item.

Edit services

You must enter the values of PrefixID, Type, and URL. A Prefix ID value must be unique.

Service Definition
Column		Description
Default	PrefixID	PrefixID of Service
	Type	Service Type
	URL	Url of the Service
	CacheLevel	Whether and what type of caching to use
	Version	Service version information
	Communication version	Communication version information
Extension	Include Sub-directory	Whether to display the subdirectory of the URL if the type is "form", "file" or "js". For theme and imagerc and extlib in Resource Service, this option defaults to "true", which is unchangeable.
	FileExtension	List of the extensions of the files that can be managed in the service (This function is applicable when the service type is file. example: js;txt;xfdl,xml)
	ServiceList	Used when Type is bs, metadata
	DataSchema	Enabled if Type is bs, metadata. model
	Search Column	Enabled if Type is metadata You can designate a column that will be searched when you search for a certain date piece through the metadata dialog. If unspecified, all columns will be searched. Commas (,) or semicolons (;) can be used as dividers.

If you set the Include Sub-directory option to "true" for a certain service, [New Folder] will be activated in the context menu opened from the relevant service in the Project Explorer.

The below table presents the file extensions supported for each type.

Service Definition
Type	File extension
none	nothing
form	.xfdl, .xjs, *.js
js	.js, .xjs
file	.
JSP	nothing
ASP	nothing
SAP	nothing
bs	XML
metadata	XML
model	*.xmodel

The below table shows which editor will be launched when you double-click a certain file in the Project Explorer.

Service Definition
Editor	File extension
ADL Editor	*xadl
FDL Editor	*.xfdl
Theme Editor	When a theme is double-clicked
Script Editor	.js, .xjs
XML Editor	*.xml
XCSS Editor	*.xcss
Image Viewer	.bmp, .jpg, .jpeg, .gif, .png, .jfif, .tif, .tiff, *.svg
Text Editor	.txt, .html, .jsp, .asp, .json, .css

If there is no matching editor for a selected file, an alert will pop up, asking you whether you want to open the file with the Text Editor.

Service refactoring

Nexacro Studio will automatically perform code refactoring when you change the PrefixID or URL of a service registered in the TypeDefinition. Code refactoring refers to the process of applying changes automatically.

ProtocolAdaptors

The Protocols editor is designed to register protocol adapters. Nexacro does not convert data for processing. It uses the standard Hypertext Transfer Protocol (HTTP) to deal with requests and responses. Depending on user environments,. however, you may need to convert or encrypt data for transaction.

A protocol adapter is a tool that connects different data structures. You can develop desired features easily through simple settings.

Editing protocols

You can add protocols and apply them differently according to execution environments. You can determine the type of protocol to apply by entering information on modules or classes.

New Protocol Wizard

You can add a new protocol in TypeDefinition through New Protocol Wizard. There are two ways to start the wizard.

In the Project Explorer, right-click TypeDefinition and access [Add > Protocol]
In the Project Explorer, right-click Protocols under TypeDefinition and select Add Protocol.

Take either way you like in order to add a protocol.

Item	Description
Protocol ID	Protocol ID, which is also used as a service URL ([Protocol ID]://)
PrefixID	Service prefix ID
Type	This indicates the type of a service. You can select either JSP or ASP.

You can select the type of systems to which the protocol will apply. Click the checkbox of a system you want select, and then enter necessary information in relation to the system.
