Configuration Markup:

<!ELEMENT extension (variable*)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED>


<!ELEMENT variable EMPTY>

<!ATTLIST variable

name             CDATA #REQUIRED

readOnly         (true | false)

initialValue     CDATA #IMPLIED

initializerClass CDATA #IMPLIED

description      CDATA #IMPLIED>


Examples:
The following is an example of a value variable contribution with an initial value:


 <extension point="org.eclipse.core.variables.valueVariables">
  <variable
   name="FOO_HOME"
   initialValue="/usr/local/foo">
  </variable>
 </extension>

In the example above, the specified variable is created with the initial value "/usr/local/foo". The following is an example of a value variable contribution with an initializer class:


 <extension point="org.eclipse.core.variables.valueVariables">
  <variable
   name="FOO_HOME"
   initializerClass="com.example.FooLocator">
  </variable>
 </extension>

In the example above, the variable FOO_HOME is created and the class "com.example.FooLocator" will be used to initialize the value the first time it's requested.

API Information:
Value of the attribute initializerClass must be a fully qualified name of a Java class that implements the interface org.eclipse.core.variables.IValueVariableInitializer.
