  +--org.sourceforge.jxdbcon.postgresql.PGTypes

Direct Known Subclasses:

PGArrayTypes, PGDateTimeTypes, PGNumericTypes, PGStructTypes

public class PGTypes

extends Object

The types used in the PostgreSQL database system. These are type handlers for the different types used in PostgreSQL. All types need to implement both a binary and a text mode conversion. All types except bytea in text mode will return the raw bytes transmitted by the backend as the result of getBytes.

Method Detail

doEscape

public static byte[] doEscape(byte[] input)

Escape byte data for use in a literal.

• all characters > 127 need to be escaped.
• double-escape 92 too
• make sure we only grab the right bits when converting

genericGetBytes

public static final byte[] genericGetBytes(Object row,
                                           ConversionContext ctx)

genericSetBytes

public static final void genericSetBytes(Object row,
                                         byte[] x,
                                         ConversionContext ctx)

genericSetNull

public static final void genericSetNull(Object row,
                                        ConversionContext ctx)
