All Implemented Interfaces:

java.io.Serializable

public class DefaultObjectStringConverter

extends ConvertUtilsObjectStringConverter

Default string <-> object conversion strategy.

This delegates to ConvertUtils except when the type is assignable from java.util.Date but not from java.sql.Date. In this case, the format used is (in SimpleDateFormat terms) EEE MMM dd HH:mm:ss zzz yyyy. This is the same as the output of the toString method on java.util.Date.

This should preserve the existing symantic behaviour whilst allowing round tripping of dates (given the default settings).

Method Detail

objectToString

public java.lang.String objectToString(java.lang.Object object,
                                       java.lang.Class type,
                                       java.lang.String flavour,
                                       Context context)

Converts an object to a string representation using ConvertUtils. If the object is a java.util.Date and the type is java.util.Date but not java.sql.Date then SimpleDateFormat formatting to EEE MMM dd HH:mm:ss zzz yyyy will be used. (This is the same as java.util.Date toString would return.)

Overrides:

objectToString in class ConvertUtilsObjectStringConverter

Parameters:

object - the object to be converted, possibly null

type - the property class of the object, not null

flavour - a string allow symantic differences in formatting to be communicated (ignored)

context - convert against this context not null

Returns:

a String representation, not null

stringToObject

public java.lang.Object stringToObject(java.lang.String value,
                                       java.lang.Class type,
                                       java.lang.String flavour,
                                       Context context)

Converts an object to a string representation using ConvertUtils.

Overrides:

stringToObject in class ConvertUtilsObjectStringConverter

Parameters:

value - the String to be converted, not null

type - the property class to be returned (if possible), not null

flavour - a string allow symantic differences in formatting to be communicated (ignored)

context - not null

Returns:

an Object converted from the String, not null

handleException

protected void handleException(java.lang.Exception e)

Allow subclasses to use a different exception handling strategy. This class throws a org.apache.commons.beanutils.ConversionException when conversion fails.

Parameters:

e - the Exception to be handled

Throws:

org.apache.commons.beanutils.ConversionException - when conversion fails
