##Installation
To use the library, first include it your project using Gradle
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
and:
dependencies {
compile 'com.github.10uroi:OHibernate:1.0.9'
}
##How to use
###Attached into the "MainActivity" class
public class MainActivity extends AppCompatActivity {
//I set the database path and the name
public static final String DATABASE_EXTERNAL = Environment.getExternalStorageDirectory().getPath(); //external
public static final String DATABASE_SUB = "/folderName/";
public static final String DATABASE_DB_PATH = DATABASE_EXTERNAL + DATABASE_SUB;
public static final String DATABASE_DATA_NAME = "databaseName.sqlite";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OHibernateConfig.DB_PATH = DATABASE_DB_PATH; // DATABASE PATH
OHibernateConfig.DB_NAME = DATABASE_DATA_NAME; // DATABASE NAME
}
}
###We are creating the "ExampleBean" class
@Entity(TABLE_NAME = "example", TABLE_OPERATION = Entity.TABLE_OPERATION_TYPE.DROP_AND_CREATE)
public class ExampleBean {
@Id(PRIMARY_KEY_AUTOINCREMENT = true)
private Integer id;
private String name;
private String surname;
private int age;
@Column(NAME = "active") //column customization
private boolean status;
@Column(DATETIME = true) //column customization
private String datetime;
//GETTER - SETTER
}
###We are creating the "ExampleBeanDAO" class
public class ExampleBeanDAO {
//Automatic Transactions
OHibernate<ExampleBean> oHibernate = new OHibernate<>(ExampleBean.class);
public void insert(ExampleBean exampleBean){
try {
oHibernate.insert(exampleBean); // Returns the id of the object
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
}
public void update(ExampleBean exampleBean){
try {
oHibernate.update(exampleBean);
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
}
public void delete(ExampleBean exampleBean){
try {
oHibernate.delete(exampleBean);
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
}
public ExampleBean select(Integer id){
try {
return (ExampleBean) oHibernate.where("id",id).select();
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
return null;
}
public ArrayList<ExampleBean> selectAll(){
try {
return (ArrayList<ExampleBean>) oHibernate.selectAll();
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
return null;
}
public ArrayList<ExampleBean> selectAll(String surname){
try {
return (ArrayList<ExampleBean>) oHibernate.where("surname",surname).limit(5).selectAll(); // custom
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
return null;
}
public ExampleBean selectCustom(String name,String surname){
try {
return (ExampleBean) oHibernate.where("name",name).and().where("surname",surname, LIKE_TYPE.BOTH).select(); // custom
} catch (Exception e) {
e.printStackTrace();
Log.e("Error",e.getMessage());
}
return null;
}
