Examples of IValueVariable

org.eclipse.core.variables.IValueVariable
A variable with a value that can be set and retrieved. The context in which a value variable is referenced does not affect the value of the variable. A value variable can be contributed by an extension or created programmatically. A contributor may optionally specify an initial value for a variable, or provide a delegate that will initialize the variable with a value.
Since 3.3, a variable can be specified as a "read only" preventing users from changing the value after it has been initialized. Furthermore, a read only variable that is contributed by an extension will always load the value from the extension.

Example of a value variable contribution with an initial value, the specified variable is created with the initial value "/usr/local/foo".
```
 <extension point="org.eclipse.core.variables.valueVariables"> <variable name="FOO_HOME" initialValue="/usr/local/foo"> </variable> </extension> 
```
Example of a value variable contribution with an initializer class, the class "com.example.FooLocator" will be used to initialize the value the first time it's requested.
```
 <extension point="org.eclipse.core.variables.valueVariables"> <variable name="FOO_HOME" initializerClass="com.example.FooLocator"> </variable> </extension> 
```
