import org.springframework.core.MethodParameter;

 Interface that defines type conversion methods. Typically (but not necessarily)
 implemented in conjunction with the PropertyEditorRegistry interface.

public interface TypeConverter {

	
 Convert the value to the required type (if necessary from a String).
 Conversions from String to any type will typically use the setAsText
 method of the PropertyEditor class. Note that a PropertyEditor must be registered
 for the given class for this to work; this is a standard JavaBeans API.
 A number of PropertyEditors are automatically registered.
 
 Parameters:value the value to convertrequiredType the type we must convert to
 (or null if not known, for example in case of a collection element) Returns:the new value, possibly the result of type conversion Throws:TypeMismatchException if type conversion failed See also:java.beans.PropertyEditor.setAsText(java.lang.String)java.beans.PropertyEditor.getValue()
