DxTimer.Cancellable	The result is triggered by the DxTimer, used only to cancel the scheduled task.
SymbolObjectVisitor<T>	Visitor interface for SymbolObjectMap entries.

Class Summary

Class	Description
ByteArrayBuffer	Deprecated No replacement
ByteArrayDataInput	Deprecated Use ByteArrayInput class instead.
ByteArrayDataOutput	Deprecated Use ByteArrayOutput class instead.
CompactChar	Deprecated Use IOUtil class instead.
CompactInt	Deprecated Use IOUtil class instead.

SymbolObjectMap<T>	Specialized hash map that maps (cipher, symbol) pair that denote symbol to an arbitrary Object of type T.
SymbolSet	Specialized hash set that contains (cipher, symbol) pair that denote symbol.
SymbolSet.ListSet
TimeFormat	Deprecated Use TimeFormat
TimeMarkUtil
TimePeriod	Deprecated Use TimePeriod
TimeSequenceUtil	Conversion methods between long time millis and time sequence.
