Class SwingExecSync

java.lang.Object

eu.bandm.tools.util.SwingExecSync

public abstract class SwingExecSync
extends Object

Worker for transparently executing code which accesses swing resources. The payload code must be defined by overriding code(). A call to run() executes this code immediately iff the thread is already the swing event dispatch thread. Otherwise it is called indirectly/later by SwingUtilities.invokeAndWait(java.lang.Runnable). The payload code can place a calculation result in the buffer result.
