Class Summary

Assert	Class for checking program invariants.
Database	This class emulates relational database on top of Perst storage It maintain class extends, associated indices, prepare queries.
IterableIterator<T>	Interface combining both Iterable and Iterator functionality
Key	Class for specifying key value (needed to access obejct by key usig index)
L2List	Double linked list.
L2ListElem	Double linked list element.
MappedFile	Class using NIO mapping file on virtual mapping.
MemoryUsage	Information about memory usage for the correspondent class.
NullFile	This implementation of IFile interface can be used to make Perst an main-memory database.
PatriciaTrieKey	Convert different type of keys to 64-bit long value used in PATRICIA trie (Practical Algorithm To Retrieve Information Coded In Alphanumeric)
Persistent	Base class for all persistent capable objects
PersistentCollection<T>
PersistentComparator<T extends IPersistent>	Base class for persistent comparator used in SortedCollection class
PersistentResource	Base class for persistent capable objects supporting locking
PersistentString	Class encapsulating native Java string. java.lang.String is not persistent object so it can not be stored in Perst as independent persistent object.
Projection<From extends IPersistent,To extends IPersistent>	Class use to project selected objects using relation field.
Rectangle	R2 rectangle class.
RectangleR2	R2 rectangle class.
Relation<M extends IPersistent,O extends IPersistent>	Class representing relation between owner and members
StorageFactory	Storage factory
StorageListener	Listener of database events.
TimeSeries.Block	Abstract base class for time series block.
Version	Base class for version of versioned object.
VersionHistory<V extends Version>	Collection of version of versioned object.

Exception Summary

CompileError	Exception thrown by compiler
JSQLArithmeticException	Exception thown in case of incorect operands for integer operations
JSQLNoSuchFieldException	Exception thown when field is not found during runtime lookup
JSQLNullPointerException	Exception thown when null reference field is dereferenced
JSQLRuntimeException	Exception thown by JSQL at runtime which should be ignored and boolean expression caused this exption should be treated as false
StorageError	Exception throw by storage implementation
XMLImportException	Exception thrown during import of data from XML file in database
