Primitive Data

Primitive data are characterized by having a simple storage in the audit trail, allowing highly efficient retrieval and usage in queries. Their values are directly stored in the indexed fields string_value or number_value of the data_value table. To specify a primitive data, create a data as described in chapter Specifying Data and set properties in the data properties dialog.

• Setting general Properties
• Specifying the Primitive Type
  • Setting a default Value
  • Wrapper Types
  • Using the Enumeration Type
  • Setting Timestamp Type Values

Setting general Properties

In the General properties section, choose an ID and name for the workflow data. Note that IDs containing hyphens, blanks or dots and IDs starting with digits are not supported. If you select the Visibility Public check box, the data becomes visible and available for reference from any other model.

Figure: Data Properties Dialog for Primitive Data

Specifying the Primitive Type

You can specify the type of a Primitive data in its properties page:

1. Select the Primitive Type entry on the left side of the properties pane.
2. Click the drop-down list for the Type selection.

   

The following primitive types are provided:

• Calendar (deprecated)
• Enumeration
• String
• Timestamp
• boolean
• byte
• char
• double
• float
• int
• long
• short

Note
Please note that the type Calendar is deprecated as it can cause problems in queries. Please use the type Timestamp instead.

Setting a default Value

You can set a default value of the selected type for your Primitive data This default value can be used in In-data paths and can be overwritten by Out-data paths.

Note that an exception are Primitive Data of type Enumeration, please refer to section Using the Enumeration Type for details.

Wrapper Types

Primitive Java types behave in method paths as their class equivalent wrapper types, e.g. type int behaves like a java.lang.Integer.

Using the Enumeration Type

If you select the Enumeration Type, a Structure field opens, where all Enumeration Types defined for the model are available. Refer to section Enumeration Type of chapter Defining Structured Types for details on defining Enumeration type structures.

In the Structure field, select the Enumeration type structure you like to use for your Primitive data.

Figure: Select Enumeration Structure

For Java-based Enumeration types, you can select a default value for your data in the Default Value drop-down list. The list contains all values available for the selected Enumeration type structure. Note that default values can not be selected for primitive Enumeration types that are not Java-based.

Setting Timestamp Type Values

To choose values for Timestamp or Calendar (deprecated) data types, a calendar is provided to select the date from. Click the arrow on the right side of the Default Value entry field to open the calendar dialog and choose the date.

To clear the Default Value entry field, select the Reset button on the right side of the entry field as shown in the following screenshot:
