Class AutoModel

java.lang.Object
  com.zentense.step2.model.ResultSetModel
      com.zentense.step2.model.AutoModel

Direct Known Subclasses:

AutoI18NModel

public class AutoModel
extends ResultSetModel

An AutoModel is a ResultSetModel defined in the application model file, and automatically created and initialized by 2step. Instances of this object are obtained when using keyword model on 2step. For instance if you define a model called Customer in the application model file, the expression model.Customer returns an AutoModel.

AutoModels extends ResultSetModel by adding finders, which are defined in the application model file, and support compound primary keys. Finders are parametrized SQL queries (similar to prepared statements) that can be easily invoked from 2step: model.<name>::findById(<pk1>, ... , <pkn>) or a model.<name>::deleteById(<pk1>, ... , <pkn>). These two finders (findById and deleteById) are automatically generated by 2step (application model when compiled generates a file called ModelInit.java where all the AutoModels used in the application are initialized), but more finders can be defined in the application model file. From Java findById finder may be also invoked this way: find(vm, "findById", new Object[]{pk1, ... pkn})

Any AutoModel also includes a prepared statement for inserting (called insert) and updating (called update) all the rows (auto incremental identifiers are excluded from inserts). For instance insert prepared statement can be invoked from 2step with model.<name>::insert(<col1>, ... , <coln>) or from Java wit prepare(vm, "insert", new Object[]{<col1>, ... , <coln>})
