Number Converter - Sun Java Studio Creator 2

See Also | Tutorials

Converts between java.lang.String values in your component properties and data types of java.lang.Number. The conversion usually applies to the property a component uses to display values and to pick up values entered by users. For example, the Text Field component uses the text property for this purpose.

Note: The Number Converter returns a Long if possible (within the range [Long.MIN_VALUE, Long.MAX_VALUE] and with no decimals), otherwise a Double. If you need the converter to return a numerical type other than Long or Double, or you need to narrow the choice to a specific type, choose a converter that specifically returns that type, such as Integer Converter, Long Converter, or Double Converter.

When you bind a component, the IDE normally identifies the data type for you and sets the appropriate converter when you establish a binding to the value property. However, you can also add a converter manually by setting the component's converter property.
