Property value

Table 10–2 identifies the value types you can use with the mergeprop utility to manage property files. These property files allow you to:

Use the value of another existing property by reference.
Specify a list of any number of syntactically valid values. The list entries are evaluated sequentially, and the first to be successfully resolved is the value of the property.
Specify a hexadecimal value.

In addition, two special value types can be included in the delta file specified with the mergeprop utility. (See the "Delta file" section.) These value types are valid only in the context of a delta file:

A value formed by appending a specified string to a current value.
A system-generated globally unique identifier (UUID, or universally unique ID).
