Class JdbcConverter<T>

java.lang.Object

io.datafx.io.converter.JdbcConverter<T>

Type Parameters:

T - The type of the converted objects.

All Implemented Interfaces:

Converter<java.sql.ResultSet,T>

public abstract class JdbcConverter<T>
extends java.lang.Object
implements Converter<java.sql.ResultSet,T>

A Converter implementation that translates a ResultSet into objects of type T. The convertOneRow(java.sql.ResultSet) method should be implemented by consumers of this class.

Method Detail

initialize

public void initialize(java.sql.ResultSet input)
                throws java.io.IOException

Description copied from interface: Converter

Initialize the raw data. In many cases, some initialization is required on the raw data before the conversion to one or more objects can be performed. In the case of an XmlConverter, for example, the DOM-model is created in this method.

Specified by:

initialize in interface Converter<java.sql.ResultSet,T>

Parameters:

input - the raw input.

Throws:

java.io.IOException - in case the raw input can't be processed by this converter.

get

public T get()

Description copied from interface: Converter

Get the next available data entity in the desired type

Specified by:

get in interface Converter<java.sql.ResultSet,T>

Returns:

the next available data

convertOneRow

public abstract T convertOneRow(java.sql.ResultSet resultSet)

Implementation-specific conversion between a resultSet and a java object of type T.

Parameters:

resultSet - the resultset, obtained by the JDBC call.

Returns:

the converted object of type T

next

public boolean next()

Description copied from interface: Converter

Indicate whether or not more data can be expected from this converter. It is up to the implementation to detect if we can deliver more data entities or not. If this method returns false a call to Converter.get() will fail.

Specified by:

next in interface Converter<java.sql.ResultSet,T>

Returns:

true if more data can be obtained from this converter, false otherwise
