Class Summary

Class	Description
AsciiStringInterner	Provides the canonicalization/interning of String instances which contain only ascii characters, keyed by the byte[] representation (in ascii).
AsciiStringInterner.BaseKey
AsciiStringInterner.Key	Instance used for inserting values into the cache.
AsciiStringInterner.TempKey	Only used for lookups, never to actually store entries.
BaseQueryKey	This class is used as a cache key for simple statements that have no "returning columns".
CachedQuery	Stores information on the parsed JDBC query.
CachedQueryCreateAction	Creates an instance of CachedQuery for a given connection.
CallableQueryKey	Serves as a cache key for CallableStatement.
CommandCompleteParser	Parses oid and rows from a CommandComplete (B) message (end of Execute).
ConnectionFactory	Handles protocol-specific connection setup.
Encoding	Representation of a particular character encoding.
EncodingPredictor	Predicts encoding for error messages based on some heuristics.
EncodingPredictor.DecodeResult	In certain cases the encoding is not known for sure (e.g.
EncodingPredictor.Translation
Field
FixedLengthOutputStream	A stream that refuses to write more than a maximum number of bytes.
JdbcCallParseInfo	Contains parse flags from Parser.modifyJdbcCall(String, boolean, int, EscapeSyntaxCallMode).
NativeQuery	Represents a query that is ready for execution by backend.
Notification
Oid	Provides constants for well-known backend OIDs for the types we commonly use.
Parser	Basic query parser infrastructure.
PgMessageType	PostgreSQL protocol message types
PGStream	Wrapper around the raw connection to the server that implements some basic primitives (reading/writing formatted data, doing string encoding, etc).
QueryExecutorBase
QueryExecutorCloseAction	The action performs connection cleanup, so it is properly terminated from the backend point of view.
QueryWithReturningColumnsKey	Cache key for a query that have some returning columns.
ResultHandlerBase	Empty implementation of ResultHandler interface.
ResultHandlerDelegate	Internal to the driver class, please do not use in the application.
SetupQueryRunner	Poor man's Statement & ResultSet, used for initial queries while we're still initializing the system.
SetupQueryRunner.SimpleResultHandler
SocketFactoryFactory	Instantiates SocketFactory based on the PGProperty.SOCKET_FACTORY.
SqlCommand	Data Modification Language inspection support.
Tuple	Class representing a row in a ResultSet.
Utils	Collection of utilities used by the protocol-level code.
VisibleBufferedInputStream	A faster version of BufferedInputStream.

Enum Summary

Enum	Description
JavaVersion
Parser.SqlParseState

ServerVersion	Enumeration for PostgreSQL versions.
SqlCommandType	Type information inspection support.
TransactionState
