Class ConversionHelper

com.polarion.core.util.types.ConversionHelper

public class ConversionHelper
extends Object

Helper for type conversions.

The general contract applied for the conversion methods of this class is that

• when object is null, defaultValue is returned
• when object is an instance of the desired type, reference to it is returned
• when the conversion fails, defaultValue is returned
• null is returned only in the case when both object and defaultValue are null
