Package com.polarion.core.util

Class RunnableWEx<T>

java.lang.Object

com.polarion.core.util.RunnableWEx<T>

All Implemented Interfaces:

Runnable

public abstract class RunnableWEx<T>
extends Object
implements Runnable

Runnable which permits the execution of a set of operations that can throw exceptions and/or return a result.
It is used in many Polarion API calls, for example: com.polarion.platform.persistence.IDataService#doInBaseline(String, RunnableWEx)
When the run() method is used, the exceptions are handled, when the runWEx()("run with exception") method is used, the exceptions are propagated and can additionally return the results of the operations.
