Constructor Detail

ToStringFieldHandler

public ToStringFieldHandler(Class type)

Creates a new ToStringFieldHandler.

Parameters:

type - the class type to create the FieldHandler for

ToStringFieldHandler

public ToStringFieldHandler(Class type,
                            FieldHandler handler)

Creates a new ToStringFieldHandler.

Parameters:

type - the class type to create the FieldHandler for

handler - the FieldHandler to wrap

Method Detail

convertUponGet

public Object convertUponGet(Object value)

This method is used to convert the value when the getValue method is called. The getValue method will obtain the actual field value from given 'parent' object. This convert method is then invoked with the field's value. The value returned from this method will be the actual value returned by getValue method.

Specified by:

convertUponGet in class GeneralizedFieldHandler

Parameters:

value - the object value to convert after performing a get operation

Returns:

the converted value.

See Also:

GeneralizedFieldHandler.convertUponGet(java.lang.Object)

convertUponSet

public Object convertUponSet(Object value)

This method is used to convert the value when the setValue method is called. The setValue method will call this method to obtain the converted value. The converted value will then be used as the value to set for the field.

Specified by:

convertUponSet in class GeneralizedFieldHandler

Parameters:

value - the object value to convert before performing a set operation

Returns:

the converted value.

See Also:

GeneralizedFieldHandler.convertUponSet(java.lang.Object)

getFieldType

public Class getFieldType()

Returns the class type for the field that this GeneralizedFieldHandler converts to and from. This should be the type that is used in the object model.

Specified by:

getFieldType in class GeneralizedFieldHandler

Returns:

the class type of of the field

GeneralizedFieldHandler.getFieldType()
