Context to invoke an extension from
DynamicMap.
When the plugin extension is invoked a logging tag with the plugin name is set. This way any
errors that are triggered by the plugin extension (even if they happen in Gerrit code which is
called by the plugin extension) can be easily attributed to the plugin.
The run* methods execute the extension but don't deliver a result back to the caller.
Exceptions can be caught and logged.
The call* methods execute the extension and deliver a result back to the caller.
Map results = new HashMap<>();
fooPluginMapEntryContext.run(
extension -> results.put(extension.getExportName(), extension.get().getFoo());
Example if all exceptions, but one, should be caught and logged:
Map results = new HashMap<>();
try {
fooPluginMapEntryContext.run(
extension -> results.put(extension.getExportName(), extension.get().getFoo(),
MyException.class);
} catch (MyException e) {
// handle the exception
}
Example if return values should be handled:
Object result = fooPluginMapEntryContext.call(extension -> extension.get().getFoo());
Example if return values and a single exception should be handled:
Object result;
try {
result = fooPluginMapEntryContext.call(extension -> extension.get().getFoo(), MyException.class);
} catch (MyException e) {
// handle the exception
}
Example if several exceptions should be handled:
for (Extension fooExtension : fooDynamicMap) {
try (TraceContext traceContext = PluginContext.newTrace(fooExtension)) {
fooExtension.get().doFoo();
} catch (MyException1 | MyException2 | MyException3 e) {
// handle the exception
}
}
