| <b><i>Identifier: </i></b>org.eclipse.debug.core.simpleLaunchVariables<p> |
| <b><i>Since: </i></b>3.0<p> |
| <b><i>Description: </i></b>This extension point provides a mechanism for defining simple launch configuration variables. A simple launch variable is a key/value pair (of strings) that can be used as an attribute value in a launch configuration which supports variable expansion.<p><b><i>Configuration Markup:</i></b><p> |
| <p><samp><font color="#800000"> <!ELEMENT <a name="e.extension">extension</a> (<a href="#e.variable">variable</a>*)></font></samp> |
| <br><br><samp><font color="#800000"> <!ATTLIST extension</samp> |
| <br><samp> point CDATA #REQUIRED</samp> |
| <br><samp> id CDATA #IMPLIED</samp> |
| <br><samp> name CDATA #IMPLIED</samp> |
| <br><samp> ></font></samp> |
| <ul> |
| <li><b>point</b> - a fully qualified identifier of the target extension point</li> |
| <li><b>id</b> - an optional identifier of the extension instance</li> |
| <li><b>name</b> - an optional name of the extension instance</li> |
| </ul> |

| <br><br><samp><font color="#800000"> <!ATTLIST variable</samp> |
| <br><samp> name CDATA #REQUIRED</samp> |
| <br><samp> initialValue CDATA #IMPLIED</samp> |
| <br><samp> initializerClass CDATA #IMPLIED</samp> |
| <br><samp> description CDATA #IMPLIED</samp> |
| <br><samp> ></font></samp> |
| <ul> |
| <li><b>name</b> - specifies a unique name for this variable.</li> |
| <li><b>initialValue</b> - specifies the initial value for this variable. When specified, an <samp>initializerClass</samp> attribute must not be specified.</li> |
| <li><b>initializerClass</b> - specifies the fully qualified name of the Java class that implements <samp>org.eclipse.debug.core.variables.ILaunchVariableInitializer</samp>. When specified, an <samp>initialValue</samp> attribute must not be specified.</li> |
| <li><b>description</b> - specifies a human-readable description of this variable</li> |
| </ul> |
| <b><i>Examples: </i></b>The following is an example of a launch configuration variable extension point with an initial value: |
| |
| <p> |
| <pre> |
| <font color="#000080"><extension point=<font color="#008000">"org.eclipse.debug.core.simpleLaunchVariables"</font>></font> |
| <font color="#000080"><variable |
| name=<font color="#008000">"FOO_HOME"</font> |
| initialValue=<font color="#008000">"/usr/local/foo"</font>></font> |
| <font color="#000080"></variable></font> |
| <font color="#000080"></extension></font> |
| </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 launch configuration variable extension point with an initializer class: |
| <p> |
| <pre> |
| <font color="#000080"><extension point=<font color="#008000">"org.eclipse.debug.core.simpleLaunchVariables"</font>></font> |
| <font color="#000080"><variable |
| name=<font color="#008000">"FOO_HOME"</font> |
| initializerClass=<font color="#008000">"com.example.FooLocator"</font>></font> |
| <font color="#000080"></variable></font> |
| <font color="#000080"></extension></font> |
| </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.<p> |
| <b><i>API Information: </i></b>Value of the attribute <b>initializerClass</b> must be a fully qualified name of a Java class that implements the interface <b>org.eclipse.debug.core.variables.IVariableInitializer</b>.<p> |
