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>.
