Exception Summary

AssertionViolatedException
BlockNotGuidVerifiableException	The BlockNotGuidVerifiableException is thrown when an attempt is made to compute or verify the guid of a block that that has not yet been archived.
InvalidConfigFileException	An exception caused by incorrect or incomplete config files.
QSException	An exception class thrown during decode when it becomes clear that the encoded data does not represent an object of the type it is trying to be decoded to.
TypeTable.DuplicateTypeCode	An exception class thrown when a given type code is passed to TypeTable.register_type(java.lang.String) for the second time with a different Java type than the original call.
TypeTable.NoSuchTypeCode	An exception class thrown when a request to TypeTable.new_object(ostore.util.InputBuffer) passes in an un-registered type code.
TypeTable.NotQuickSerializable	An exception class thrown when the object named by the parameter name to TypeTable.register_type(java.lang.String) does not refer to a class which implements QuickSerializable.
