Example 1 with BindStatementMethod

use of com.coredata.compiler.method.BindStatementMethod in project CoreData by FangCloud-Android.

the class EntityProcessor method createEntityDao.

    // 1、找出tableName,PrimaryKeyName ok
    // 2、找出所有的PropertyConverter,并生成局部变量,类似 __TagListConverter ok
    // 3、找出所有关联对象 @Relation,并生成对应的dao 类似 __AuthorCoreDao ok
    // 4、onCreate方法,初始化 关联对象对应的 dao ok
    // 5、getInsertSql, 返回插入的sql语句 ok
    // 6、getCreateTableSql,返回建表语句
