This extension point provides a mechanism for defining variables used for string substitution. A value variable has a static value.
a fully qualified identifier of the target extension point
an optional identifier of the extension instance
an optional name of the extension instance
specifies a unique name for this variable.
specifies the initial value for this variable. When specified, an <code>initializerClass</code> attribute must not be specified.
specifies the fully qualified name of the Java class that implements <code>org.eclipse.core.variables.IValueVariableInitializer</code>. When specified, an <code>initialValue</code> attribute must not be specified.
specifies a human-readable description of this variable.
3.0
The following is an example of a value variable contribution with an initial value:
<p>
<pre>
<extension point="org.eclipse.core.variables.valueVariables">
<variable
name="FOO_HOME"
initialValue="/usr/local/foo">
</variable>
</extension>
</pre>
</p>
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:
<p>
<pre>
<extension point="org.eclipse.core.variables.valueVariables">
<variable
name="FOO_HOME"
initializerClass="com.example.FooLocator">
</variable>
</extension>
</pre>
</p>
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.
Value of the attribute <b>initializerClass</b> must be a fully qualified name of a Java class that implements the interface <b>org.eclipse.core.variables.IValueVariableInitializer</b>.
