Class Summary
Class	Description
AppRequester	AppRequester stores information about the application requester.
CcsidManager
CharacterEncodings
ClientThread
CodePoint
CodePointNameTable	This class has a hashtable of CodePoint values.
ConsistencyToken	Class which represents an RDB Package Consistency Token.
Database	Database stores information about the current database It is used so that a session may have more than one database
DDMReader	The DDMReader is used to read DRDA protocol.
DDMWriter	The DDMWriter is used to write DRDA protocol.
DecryptionManager	This class is used to decrypt password and/or userid.
DRDAConnThread	This class translates DRDA protocol from an application requester to JDBC for Derby and then translates the results from Derby to DRDA for return to the application requester.
DRDAConnThread.PublicBufferOutputStream
DRDAProtocolExceptionInfo
DRDAResultSet	DRDAResultSet holds result set information
DRDAStatement	DRDAStatement stores information about the statement being executed
DRDAStatement.DrdaParamState	This class is used to keep track of the statement's parameters as they are received from the client.
DRDAString	This class provides functionality for reusing buffers and strings when parsing DRDA packets.
DRDAXAProtocol	This class translates DRDA XA protocol from an application requester to XA calls for Derby and then translates the results from Derby to DRDA for return to the application requester.
DRDAXid
DssConstants	This class defines DSS constants that are shared in the classes implementing the DRDA protocol.
DssTrace
EbcdicCcsidManager	A concrete implementation of a CcsidMgr used to convert between Java UCS2 and Ebcdic as needed to handle character DDM Parameters.
EXTDTAInputStream	EXTDTAObjectHolder provides Externalized Large Object representation that does not hold locks until the end of the transaction (DERBY-255) It serves as a holder for lob data and is only valid as long as the original result set from which it came is on the same row.
EXTDTAReaderInputStream	Implementation of InputStream which get EXTDTA from the DDMReader.
FailingEXTDTAInputStream	A stream class that throws an exception on the first read request.
FdocaConstants
LayerBStreamedEXTDTAReaderInputStream	Implementation of InputStream which get EXTDTA from the DDMReader.
memCheck
NaiveTrustManager	This is a naive trust manager we use when we don't want server authentication.
NetworkServerControlImpl	NetworkServerControlImpl does all the work for NetworkServerControl
NetworkServerMBeanImpl	This is an implementation of the `org.apache.derby.mbeans.drda.NetworkServerMBean`, providing management and monitoring capabilities related to the Network Server through JMX.
PiggyBackedSessionData	Tracks the most recently piggy-backed session attributes, and provides methods to determine if they have been modified and need to be re-sent to the client.
Pkgnamcsn	Class representing a PKGNAMCSN object (RDB Package Name, Consistency Token, and Section Number).
ProtocolTestAdapter	Adapter written to allow for protocol testing from the test package.
ReEncodedInputStream	ReEncodedInputStream passes stream from Reader, which is stream of decoded style, to user of this subclass of InputStream, which is stream of encoded style.
ReEncodedInputStream.PublicBufferOutputStream
Session	Session stores information about the current session It is used so that a DRDAConnThread can work on any session.
SignedBinary	Converters from signed binary bytes to Java `short`, `int`, or `long`.
SQLTypes
StandardEXTDTAReaderInputStream	Implementation of InputStream which get EXTDTA from the DDMReader.
Utf8CcsidManager
XADatabase	This class contains database state specific to XA, specifically the XAResource that will be used for XA commands.

Exception Summary
Exception	Description
DRDAProtocolException
DRDASocketTimeoutException	Class used to transport that fact that we had a timeout and should NOT disconnect the connection.
