Method Detail

convertToObject

public java.lang.Object convertToObject(int phase,
                                        java.lang.String newString,
                                        java.lang.Object previousValue)
                                 throws DataTypeConversionException
Convert the input string to a date. Throw an exception on error.
Parameters:
phase - int The current validation phase. The phase can be one of the following:
	FORM_NOTIFICATION_IMMEADIATE : Typically no validation is performed in this case the input string is returned as is.
	FORM_NOTIFICATION_ON_FOCUS_CHANGE 	 
 	FORM_NOTIFICATION_ON_REQUEST
	
newString - The String to convert.
Returns:
An object representing the converted String or null.
Overrides:
convertToObject in class UIDataType
See Also:
IDataType.convertToObject(int, String, Object)

convertToString

public java.lang.String convertToString(java.lang.Object object,
                                        boolean forEditing)
Return the String represenation of the object or the empty string if object is null. The default implementation calls the toString() to return a string representation of the object. Subclasses should override this method to return the formatted data type as a String.
Overrides:
convertToString in class UIDataType
See Also:
IDataType.convertToString(Object, boolean)

filterInput

public java.lang.String filterInput(java.lang.String newString)
The default implementation returns original string without modification.
Overrides:
filterInput in class UIDataType
See Also:
IDataType.filterInput(String)

free

public void free()
The receiver is being destroyed. Release all the associated resources.
Overrides:
free in class com.ibm.ulc.ui.UIProxy

handleRequest

public void handleRequest(ORBConnection conn,
                          java.lang.String request,
                          Anything args)
The ULC application has sent a request to this object. Do all processing necessary. If this object does not handle this request call super.handleRequest.
Parameters:
conn - ORBConnection The connection on which the reply should be sent.
request - String The string that identifies this request.
args - Anything The arguments associated with this request.
Overrides:
handleRequest in class com.ibm.ulc.ui.UIProxy

hasValidCharacters

public boolean hasValidCharacters(java.lang.String s)

restoreState

public void restoreState(ORBConnection conn,
                         Anything args)
This method is the first method called after this widget is instantiated. All widget specific initialization must take place in this method. All the parameters necessary to initialize this widget are specified in the arguments. Subclasses implementing this method must call the superclass implementation as well.
Parameters:
conn - the UlcConnection in which this operation is performed
args - the Anything containing the optional initialization parameters
Overrides:
restoreState in class com.ibm.ulc.ui.UIProxy

setFormatString

public void setFormatString(java.lang.String formatString)
