A global definition defines a constant value, including data type, for the application. This value can be referenced throughout the application, both by the attributes of other definition types and for use in synchronization components. A global value cannot be changed on the Client at run-time but can be overridden during synchronization.
A global’s value is constant and cannot be modified on the Agentry Client. It can be overridden at run time during synchronization.
- Boolean: A value that may be either true or false.
- Date: A value representing a calendar date.
- Date and Time: A value containing a calendar date and time of day.
- Decimal Number: A numeric value that contains a fractional portion and that may be positive or negative.
- Duration: A value containing a duration of time in hours, minutes, and seconds.
- Identifier: A numeric value that is primarily used to represent an identifying value. Can contain whole, positive numeric values.
- Integral Number: A numeric value containing whole numbers that may be positive or negative.
- Selection: A special data type for a global definition that represents an attribute setting that is selected from a list. This data type cannot be selected when defining a global, but rather is the automatic data type of the global when it is created specifically for an attribute whose setting is selected from a drop-down list in the Editor. Valid values for this type of global are those found in the specific list for the attribute.
- String: A value containing alphanumeric or other printable characters.
- Time: A value containing a time of day.
The data type of a global is important as it will determine where in the application the Global can be used. The data type of the attribute and the global definition used to set it must be the same. For example, string properties contain attributes for their size, i.e., the number of characters they can contain. This size attribute is an integral number. This then requires the user of a global with a data type of integral number.
A global definition may be added to the application project from either the list of globals for the application, or at the point where it will be referenced by another attribute that may be set via a global. In the latter case, the data type of the global is set automatically based on the data type for that attribute.
- Global Type: The data type of the global, selected when the global is added to the application, or set automatically by the Editor based on the attribute to use the global for its setting.
- Group: The group into which the global definition will be organized. Unlike the group setting for other definitions, a global’s group is a required attribute. References to the global definition throughout the application must include its group as well as its name.
- Name: The unique identifier for the global definition. This value must be unique among all global definitions within the same group.
- Value: The value of the global definition returned when the global is referenced. Valid values for a global depend on its defined Global Type.
