Assert a good practice or not ?
- by rkenshin
Is it a good practice to use Assert for function parameters to enforce their validity. I was going through the source code of Spring Framework and I noticed that they use Assert.notNull a lot. Here's an example
public static ParsedSql parseSqlStatement(String sql) {
Assert.notNull(sql, "SQL must not be null");}
Here's Another one
public NamedParameterJdbcTemplate(DataSource dataSource) {
Assert.notNull(dataSource,
"The [dataSource] argument cannot be null.");
this .classicJdbcTemplate = new JdbcTemplate(dataSource);
}
public NamedParameterJdbcTemplate(JdbcOperations classicJdbcTemplate) {
Assert.notNull(classicJdbcTemplate,
"JdbcTemplate must not be null");
this .classicJdbcTemplate = classicJdbcTemplate;
}
Thank you
