ImageSingletons, using this interface as the key, at Feature.duringSetup() time:
class LogHandlerFeature implements Feature {
@Override
public void duringSetup(DuringSetupAccess access) {
ImageSingletons.add(LogHandler.class, new CustomLogHandler());
}
}
If no custom log handler is installed, a default is installed
Feature.beforeAnalysis() before the static analysis. The default handler prints log
messages to the standard output. Installing a custom log handler at a later time, after the
default one has been installed, results in an error.
The methods defined in this interface are called from places where Java object allocation is not possible, e.g., during a garbage collection or before the heap is set up. If an implementation of the interface allocates a Java object or array, an error is reported during image generation.

| public void |
| fatalError | back to summary |
|---|---|
| public void fatalError() Exit the VM because a fatal, non-recoverable error situation has been detected. The implementation of this method must not return, and it must not throw a Java exception. A valid implementation is, e.g., to ask the OS to kill the process. The methods defined in this interface are called from places where Java object allocation is not possible, e.g., during a garbage collection or before the heap is set up. If an implementation of the interface allocates a Java object or array, an error is reported during image generation.

| flush | back to summary |
|---|---|
| public void flush() Flush the log to its destination. The methods defined in this interface are called from places where Java object allocation is not possible, e.g., during a garbage collection or before the heap is set up. If an implementation of the interface allocates a Java object or array, an error is reported during image generation.

| log | back to summary |
|---|---|
| public void log(CCharPointer bytes, UnsignedWord length) Write raw bytes to the log. The methods defined in this interface are called from places where Java object allocation is not possible, e.g., during a garbage collection or before the heap is set up. If an implementation of the interface allocates a Java object or array, an error is reported during image generation.
