Hi,
here's the relevant code:
public class Inet4AddressType implements ExtendedType {
@Override
public String getClassName() {
return Inet4Address.class.getName();
}
@Override
public void setJdbcObject(PreparedStatement statement, Object
value, int pos, int type, int scale) throws Exception {
if (value == null) {
statement.setNull(pos, type);
} else {
if (type == Types.BIGINT) {
byte[] ip = ((Inet4Address) value).getAddress();
long ipNum = 0;
ipNum += (long) (ip[0] & 0xFF) << 24; //TODO this needs
to be long-cast or it will overflow
ipNum += (ip[1] & 0xFF) << 16;
ipNum += (ip[2] & 0xFF) << 8;
ipNum += (ip[3] & 0xFF);
statement.setLong(pos, ipNum);
} else {
throw new IllegalArgumentException("Only BIGINT can be
mapped as '" + getClassName() + "', got " +
TypesMapping.getSqlNameByType(type));
}
}
}
@Override
public Object materializeObject(ResultSet rs, int index, int type)
throws Exception {
if (type == Types.BIGINT) {
long l = rs.getLong(index);
return InetAddress.getByAddress(new byte[]{(byte) ((l >>
24) & 0xFF),
(byte) ((l >> 16) & 0xFF),
(byte) ((l >> 8) & 0xFF),
(byte) (l)});
} else {
throw new IllegalArgumentException(getClassName() + "' can
only be constructed from BIGINT, got " +
TypesMapping.getSqlNameByType(type));
}
}
}
