  +--oracle.cabo.ui.data.bind.MessageFormatBoundValue

All Implemented Interfaces:

BoundValue

public class MessageFormatBoundValue

extends java.lang.Object

implements BoundValue

BoundValue implementation that will automatically format a series of objects into a string based on a format mask. All of the values, as well as the format mask, are retrieved dynamically.

MessageFormatBoundValue, by default, runs in a "fast" mode, using the FastMessageFormat class. This mode offers a limited syntax, but is much more efficient. Developers can explicitly use the full java.text.MessageFormat syntax if they wish.
