This framework method must be implemented by concrete subclasses. Any
subclass returning a Composite
object whose Layout
has default margins (for example, a GridLayout
) are expected to
set the margins of this Layout
to 0 pixels.

This is a framework hook method for subclasses to do special things when
the Defaults button has been pressed.
Subclasses may override, but should call super.performDefaults
.

public void setInitializationData(IConfigurationElement config, String propertyName, Object data)
IExecutableExtension
IConfigurationElement.createExecutableExtension
on a newly constructed extension, passing it its relevant configuration
information. Most executable extensions only make use of the first
two call arguments.
Regular executable extensions specify their Java implementation class name as an attribute of the configuration element for the extension. For example
<action run="com.example.BaseAction"/>In the above example, this method would be called with a reference to the
<action>
element (first argument), and
"run"
as the name of the attribute that defined
this executable extension (second argument).
The last parameter is for the specific use of extension adapters and is typically not used by regular executable extensions.
There are two supported ways of associating additional adapter-specific data with the configuration in a way that is transparent to the extension point implementor:
(1) by specifying adapter data as part of the implementation
class attribute value. The Java class name can be followed
by a ":" separator, followed by any adapter data in string
form. For example, if the extension point specifies an attribute
"run"
to contain the name of the extension implementation,
an adapter can be configured as
<action run="com.example.ExternalAdapter:./cmds/util.exe -opt 3"/>
(2) by converting the attribute used to specify the executable extension to a child element of the original configuration element, and specifying the adapter data in the form of xml markup. Using this form, the example above would become
<action> <run class="com.xyz.ExternalAdapter"> <parameter name="exec" value="./cmds/util.exe"/> <parameter name="opt" value="3"/> </run > </action>
Form (2) will typically only be used for extension points that anticipate the majority of extensions configured into it will in fact be in the form of adapters.
In either case, the specified adapter class is instantiated using its 0-argument public constructor. The adapter data is passed as the last argument of this method. The data argument is defined as Object. It can have the following values:
null

call. This

is used to define multiple executable extensions.data
