I have been doing some performance tuning and looking a heap dumps.
The number of Integer objects in memory is staggering. Looking at the
1.5 java docs, using Integer.valueOf should help.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Integer.html#valueOf(int)
This could be extended to most of the number type TypeHandlers in the
2.3.4 code base as it requires Java 1.5. How is this handled in 3.0?
IntegerTypeHandler (version 2.3.4 )
public Object getResult(ResultSet rs, String columnName)
throws SQLException {
int i = rs.getInt(columnName);
if (rs.wasNull()) {
return null;
} else {
return new Integer(i);
}
}
