Examples with TableModel org.litepal.tablemanager.model.TableModel used on opensource projects

Example 1 with TableModel

use of org.litepal.tablemanager.model.TableModel in project LitePal by LitePalFramework.

the class LitePalBase method getTableModel.

/**
 * This method is used to get the table model by the class name passed
 * in. The principle to generate table model is that each field in the class
 * with non-static modifier and has a type among int/Integer, long/Long,
 * short/Short, float/Float, double/Double, char/Character, boolean/Boolean
 * or String, would generate a column with same name as corresponding field.
 * If users don't want some of the fields map a column, declare an ignore
 * annotation with {@link Column#ignore()}.
 *
 * @param className
 *            The full name of the class to map in database.
 * @return A table model with table name, class name and the map of column
 *         name and column type.

Example 2 with TableModel

use of org.litepal.tablemanager.model.TableModel in project LitePal by LitePalFramework.

the class AssociationUpdater method getRemoveColumnSQLs.

/**

Example 3 with TableModel

use of org.litepal.tablemanager.model.TableModel in project LitePal by LitePalFramework.

the class TableStructureActivity method analyzeTableStructure.

    mList.addAll(columnModelList);
}

Example 4 with TableModel

use of org.litepal.tablemanager.model.TableModel in project LitePal by LitePalFramework.

the class AssociationUpdater method removeForeignKeyColumns.

/**
 * Analyzing the table models, then remove all the foreign key columns if
 * their association in model classes are no longer exist any more.
 */
private void removeForeignKeyColumns() {
    for (String className : LitePalAttr.getInstance().getClassNames()) {

 * columns of a table.
