Interface Converter<J,S>

All Superinterfaces:

Serializable

All Known Implementing Classes:

BooleanConverter, CharConverter

public interface Converter<J,S>
extends Serializable

Implementation of a data type converter. Converts on-the-fly from SAP data type to any Java type. The corresponding field in the BAPI class can thus be independent of the SAP type. E .g., a SAP character type which represents a boolean (since ABAP does not have a boolean data type) can be converted to a Java boolean. To utilize a Converter, annotate the BAPI class field using the @Convert annotation.

Method Summary

Modifier and Type	Method and Description
J	convertToJava(S sapValue) Convert the SAP value, as it is returned by the underlying interfacing technology (e.g. the SAP Java Connector, JCo) to the Java data type of the corresponding BAPI class field.
S	convertToSap(J javaValue) Convert the Java value of the corresponding BAPI class field to the data type as it is expected by the underlying interfacing technology (e.g. the SAP Java Connector, JCo).

Method Detail

convertToJava

J convertToJava(S sapValue)
         throws ConversionException

Convert the SAP value, as it is returned by the underlying interfacing technology (e.g. the SAP Java Connector, JCo) to the Java data type of the corresponding BAPI class field. Hibersap will call this method after calling the SAP function and before setting the field in the Java class.

Parameters:

sapValue - The object which is returned by the SAP interface

Returns:

The converted value

Throws:

ConversionException - if the value can not be converted

convertToSap

S convertToSap(J javaValue)
        throws ConversionException

Convert the Java value of the corresponding BAPI class field to the data type as it is expected by the underlying interfacing technology (e.g. the SAP Java Connector, JCo). Hibersap will call this method before calling the SAP function.

Parameters:

javaValue - The value of the BAPI class field

Returns:

The converted value

Throws:

ConversionException - if the value can not be converted
