v1.4.1

Issues 1.4.1

Issues 1.4.0

Csv

• Joda DateTime, LocalDate, LocalTime, LocalDateTime supports
• can provide on CellValueReaderFactory
• can specify CsvColumnDefinition via a predicate

CsvMapperFactory
    .newInstance()
    .addColumnDefinition(
        (k) -> k.getName().endsWith("_date"), 
        CsvColumnDefinition.dateFormatDefinition("yyyyMMdd")
    ).newMapper(MyObject.class)

• add convenience method to override the headers

CsvParser
    .mapTo(String.class, String.class)
    .overrideWithDefaultHeaders()
    .iterate(new StringReader("key,value\nvalue1,value2"));

CsvParser.mapTo(String.class, String.class)
    .defaultHeaders()
    .iterate(new StringReader("value1,value2"));

JdbcMapper

• Joda DateTime, LocalDate, LocalTime, LocalDateTime supports
• can specify CsvColumnDefinition via a predicate

JdbcMapperFactory
    .newInstance()
    .addColumnDefinition(
        (k) -> k.getName().endsWith("_date"), 
        columnDefinition)
    ).newMapper(MyObject.class)

v1.3.0

Issues

CsvMapper

• allow for field customisation date format or custom reader

CsvMapperFactory
    .newInstance()
    .addColumnDefinition("date", CsvColumnDefinition.dateFormatDefinition("yyyyMMdd")
    .newMapper(MyClass.class);

CsvMapperFactory.newInstance()
    .newBuilder(MyClass.class)
    .addMapping("date", CsvColumnDefinition.dateFormatDefinition("yyyyMMdd")
    .mapper();

• support tuple on the csv dsl

CsvParser.mapTo(String.class, Date.class).stream(reader);

JdbcMapper

• allow for getter customisation

JdbcMapperFactory.newInstance().addCustomGetter("id", getter).newMapper(MyClass.class);

Mapping

• support java lang type as root object

CsvParser.mapTo(String.class).stream(reader);

Sql2o integration

Query query = sql2o.open().createQuery("select * from table");
query.setResultSetHandlerFactoryBuilder(new SfmResultSetHandlerFactoryBuilder());
List<DbObject> dbObjects = query.executeAndFetch(DbObject.class);

v1.2.0

Issues

CsvMapper

• replace non fluent call with fluent dsl see CsvParser How-to-parse-a-csv-file-in-java

Reflection

• detect class loader visibility issues automatically
• fix issue with instantiator cache

Osgi

• remove osgi services and activator as now class loader issue automatically detected
• disable asm in osgi as classloader issue of bundles being refresh it's not worth it for now

JdbcMapper

• allow change of row handler error handler
