extends java.lang.Object

Field Summary

Fields

Modifier and Type	Field and Description
static boolean	atHome prints more stack traces
static boolean	checkSychronization checks monitor conditions to make sure only the thread with the global monitor is allowed entry to the core
static boolean	configureAllClasses makes sure a configuration entry is generated for each persistent class
static boolean	configureAllFields makes sure a configuration entry is generated for each persistent field
static boolean	freespace turns freespace debuggin on
static boolean	indexAllFields indexes all fields
static boolean	lockFile allows overriding the file locking mechanism to turn it off
static boolean	longTimeOuts makes C/S timeouts longer, so C/S does not time out in the debugger
static boolean	messages prints all communicated messages to the console
static boolean	nio allows turning NIO off on Java
static boolean	queries prints query graph information to the console
static boolean	staticIdentity allows faking the Db4oDatabase identity object, so the first stored object in the debugger is the actually persisted object Changing this setting to true will fail some tests that expect database files to have identity
static boolean	weakReferences allows turning weak references off
static boolean	xbytes fills deleted slots with 'X' and overrides any configured freespace filler
