Constructor Detail

SQLTimestampFieldHandler

public SQLTimestampFieldHandler()
Creates a new SQLTimestampFieldHandler

Method Detail

convertUponGet

public java.lang.Object convertUponGet(java.lang.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.

convertUponSet

public java.lang.Object convertUponSet(java.lang.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.

getFieldType

public java.lang.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

newInstance

public java.lang.Object newInstance(java.lang.Object parent)
                             throws java.lang.IllegalStateException
Creates a new instance of the object described by this field.

Specified by:
newInstance in interface FieldHandler
Overrides:
newInstance in class GeneralizedFieldHandler
Parameters:
parent - The object for which the field is created
Returns:
A new instance of the field's value
Throws:
java.lang.IllegalStateException - This field is a simple type and cannot be instantiated
