| <p><b><i>Identifier: </i></b>org.eclipse.debug.core.launchConfigurationComparators</p> |
| |
| <p><b><i>Description: </i></b>This extension point provides a configurable |
| mechanism for comparing specific attributes of a launch configuration. In general, |
| launch configuration attributes can be compared for equality via the default |
| implementation of <code>java.lang.Object.equals(Object)</code>. However, attributes |
| that require special handling should implement this extension point. For example, |
| when an attribute is stored as XML, it is possible that two strings representing |
| an equivalent attribute have different whitespace formatting.</p> |
| |
| <p><b><i>Configuration Markup:</i></b> </p> |
| |
| <pre> |
| <tt> <!ELEMENT launchConfigurationComparator</tt>> |
| <tt> <!ATTLIST launchConfigurationComparator</tt> |
| <br><tt> id CDATA #REQUIRED</tt> |
| <br><tt> attribute CDATA #REQUIRED</tt> |
| <br><tt> class CDATA #REQUIRED</tt> |
| </pre> |
| |
| <ul> |
| <li><code>id</code> specifies a unique identifier for this extension.</li> |
| <li><code>attribute</code> specifies the launch configuration attribute name that this comparator |
| compares</li> |
| <li><code>class</code> specifies a fully qualified name of a class that |
| implements <code>java.util.Comparator</code></li> |
| </ul> |
| |
| <p><b><i>Examples:</i></b> </p> |
| |
| <p>The following is an example of a launch configuration comparator extension point: </p> |
| |
| <pre> |
| <extension point="org.eclipse.debug.core.launchConfigurationComparators"> |
| <launchConfigurationComparator |
| id="com.example.ExampleIdentifier" |
| attribute="com.example.ExampleAttributeName" |
| class="com.example.ComapartorImplementation"> |
| </launchConfigurationComparator> |
| </extension> |
| </pre> |
| |
| <p>In the example above, the specified type of launch configuration comparator will be |
| consulted when comparing the equality of attributes keyed with the name |
| <code>com.example.ExampleAttributeName</code>. |
| </p> |
| |
| <p><b><i>API Information: </i></b>Value of the attribute <b>class</b> must be a fully |
| qualified name of a Java class that implements the interface <b> |
| java.util.Comparator</b>. |
