Examples of com.opensymphony.xwork2.conversion.TypeConverter.convertValue()

com.opensymphony.xwork2.conversion.TypeConverter.convertValue()
Converts the given value to a given type. The OGNL context, target, member and name of property being set are given. This method should be able to handle conversion in general without any context, target, member or property name specified. @param context context under which the conversion is being done @param target target object in which the property is being set @param member member (Constructor, Method or Field) being set @param propertyName property name being set @param value value to be converted @param toType type to which value is converted @return Converted value of type toType or TypeConverter.NoConversionPossible to indicate that theconversion was not possible.
