Java Source File NameTypeComment
BaseConnection.javaInterface Driver-internal connection interface.
BaseResultSet.javaInterface Driver-internal resultset interface.
BaseStatement.javaInterface Driver-internal statement interface.
ConnectionFactory.javaClass Handles protocol-specific connection setup.
Encoding.javaClass Representation of a particular character encoding.
Field.javaClass
Logger.javaClass Poor man's logging infrastructure.
Notification.javaClass
Oid.javaClass Provides constants for well-known backend OIDs for the types we commonly use.
ParameterList.javaInterface Abstraction of a list of parameters to be substituted into a Query.
Parser.javaClass Basic query parser infrastructure.
PGBindException.javaClass
PGStream.javaClass Wrapper around the raw connection to the server that implements some basic primitives (reading/writing formatted data, doing string encoding, etc).
ProtocolConnection.javaInterface Provides access to protocol-level connection operations.
Query.javaInterface Abstraction of a generic Query, hiding the details of any protocol-version-specific data needed to execute the query efficiently.
QueryExecutor.javaInterface Abstracts the protocol-specific details of executing a query.

Every connection has a single QueryExecutor implementation associated with it. This object provides:

Query objects may represent a query that has parameter placeholders.

ResultCursor.javaInterface Abstraction of a cursor over a returned resultset.
ResultHandler.javaInterface Callback interface for passing query results from the protocol-specific layer to the protocol-independent JDBC implementation code.

In general, a single query execution will consist of a number of calls to handleResultRows, handleCommandStatus, handleWarning, and handleError, followed by a single call to handleCompletion when query execution is complete.

UTF8Encoding.javaClass
Utils.javaClass Collection of utilities used by the protocol-level code.
