Single Value

One of eleven property modes, a property of mode Single Value has as its value a single text string of zero or more characters, with no limit on length.

Of all the property modes, Single Value properties are most heavily used, because:

• All user input into HTML forms and most user displays involve only Single Value mode properties (and the pega:reference JSP tag).
• Only Single Value mode properties can be columns in the database schema, and so only string mode properties can be used to select and search in queries.

Single Value mode properties have a Type such as Text, Password, Identifier, Date, and so on. Text type properties can contain newline characters, tab characters, and other control characters without restriction.

On the Explorer display of properties, the icon identifies a Single Value property.

PRPC uses the UNICODE UTF-8 and UTF-16 character sets for property values.

The standard property Rule-Obj-Property.pyPropertyMode holds the mode of a property. The internal value of this property for a Single Value property is String, not Single Value.

Single Value property values correspond to objects of the Java.lang.String class.
