Identifier: org.eclipse.debug.core.launchConfigurationComparators
Description: 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 java.lang.Object.equals(Object)
. 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.
Configuration Markup:
<!ELEMENT launchConfigurationComparator> <!ATTLIST launchConfigurationComparator
id CDATA #REQUIRED
attribute CDATA #REQUIRED
class CDATA #REQUIRED
id
specifies a unique identifier for this extension.attribute
specifies the launch configuration attribute name that this comparator
comparesclass
specifies a fully qualified name of a class that
implements java.util.Comparator
Examples:
The following is an example of a launch configuration comparator extension point:
<extension point="org.eclipse.debug.core.launchConfigurationComparators"> <launchConfigurationComparator id="com.example.ExampleIdentifier" attribute="com.example.ExampleAttributeName" class="com.example.ComapartorImplementation"> </launchConfigurationComparator> </extension>
In the example above, the specified type of launch configuration comparator will be
consulted when comparing the equality of attributes keyed with the name
com.example.ExampleAttributeName
.
API Information: Value of the attribute class must be a fully qualified name of a Java class that implements the interface java.util.Comparator.
