Interface OutputStreamTaskListener

All Superinterfaces:

Serializable, org.jenkinsci.remoting.SerializableOnlyOverRemoting, TaskListener

All Known Implementing Classes:

OutputStreamTaskListener.Default

@Restricted(org.kohsuke.accmod.restrictions.Beta.class)
public interface OutputStreamTaskListener
extends TaskListener

TaskListener which can directly return an OutputStream not wrapped in a PrintStream. This is important for logging since the error-swallowing behavior of PrintStream is unwanted, and PrintStream.checkError() is useless.

Method Summary

Modifier and Type	Method	Description
OutputStream	getOutputStream()	Returns the OutputStream from which TaskListener.getLogger() was constructed.
static OutputStream	getOutputStream(TaskListener listener)	Tries to call getOutputStream() and otherwise falls back to reflective access to FilterOutputStream.out when possible, at worst returning the PrintStream itself.
