java.lang.Object adapt(java.lang.Object source, java.lang.Class<T> target)
Adapt object to target type. Try to get an adapter for an object.
adapted object or null
void executeCommand(java.lang.String commandId, [java.util.Map<K, V> parameters])
Execute a command from the command framework. As we have no UI available, we do not pass a control to the command. Hence HandlerUtil.getActive... commands will very likely fail.
java.lang.Object getService(java.lang.Class<T> type)
Get a platform service.
service instance or null
java.lang.String getSystemProperty(java.lang.String key)
Get a system property value
system property for key
void postEvent(java.lang.String topic, [java.lang.Object data], [long delay])
Post an event on the event broker. If delay is set, the event will be posted after the given amount of time asynchronously. In any case this method returns immediately.
java.lang.Object readPreferences(java.lang.String node, java.lang.String key, [java.lang.Object defaultValue])
Read a preferences value. The defaultValue is optional, but contains type information if used. Provide instances of Boolean, Integer, Double, Float, Long, byte[], or String to get the appropriate return value of same type.
org.eclipse.ease.modules.platform.Future runProcess(java.lang.String name, [java.lang.String args])
Run an external process. The process is started in the background and a Future object is returned. Query the result for finished state, output and error streams of the executed process.
Future object tracking the program
org.osgi.service.event.Event waitForEvent(java.lang.String topic, [long timeout])
Wait for a given event on the event bus.
posted event or null
in case of a timeout
void writePreferences(java.lang.String node, java.lang.String key, java.lang.Object value)
Set a preferences value. Valid types for value are: Boolean, Integer, Double, Float, Long, byte[], and String.
