public class PGConversionContext

extends ConversionContext

A ConversionContext suitable to describe the data returned by the backend. PostgreSQL has 3 different contexts.

1. query result in text form
2. query result in binary form
3. function parameter pass-by-value

Adittionally two encodings are in use. Unformatted binary data is encoded in the database's encoding, formatted text data is encoded using the connections client encoding.

Field Summary

(package private) PGConnection	conn
(package private) String	encoding Which encoding is in use.
(package private) boolean	isBigEndian Is the data using Big Endian semantics.
(package private) boolean	isBinary Is the data in binary form.
(package private) boolean	isFuncCall Are we in a function call?.
