Class GenericColumn<TYPE>

java.lang.Object

org.hrorm.GenericColumn<TYPE>

Type Parameters:

TYPE - The Java type represented by the column.

public class GenericColumn<TYPE>
extends Object

A column that represents a particular Java type.

This can be used if none of the types Hrorm has built in meet the needs. The user must provide mechanisms for setting the type's value onto a java.sql.PreparedStatement and for reading a value from a java.sql.ResultSet.

For example, to create a column for Integer, do the following:

 GenericColumn<Integer> integerColumn = new GenericColumn<>(
     PreparedStatement::setInt,
     ResultSet::getInt,
     java.sql.Types.Integer);
