public interface ObjectStringConverter

Interface for classes which can convert Objects to String representations and vice versa

Method Summary

Object	convertToObject(String o, Class asClass) This method takes a String, and tries to interpret it as a String representation of the given classtype, which it will then create.
String	convertToString(Object o, Class asClass) This method takes an object, treats it as an object of the given class type and produces a String representation.

Method Detail

convertToString

public String convertToString(Object o,
                              Class asClass)
                       throws IllegalArgumentException

This method takes an object, treats it as an object of the given class type and produces a String representation.

Throws:

IllegalArgumentException - if this method is not capable of doing the transformation because of illegal arguments

Parameters:

o - the object to convert

asClass - the type which should be used to interpret the object, may be less specific than the actual object's type

Returns:

a string representation of the object

convertToObject

public Object convertToObject(String o,
                              Class asClass)
                       throws IllegalArgumentException

This method takes a String, and tries to interpret it as a String representation of the given classtype, which it will then create.

Throws:

IllegalArgumentException - if this method is not capable of doing the transformation because of illegal arguments

Parameters:

o - the String to convert

asClass - the type which should be generated by this method. the method is free to create a more specific type, but that type must be assignment compatible
