Method Detail

convert

public static <T> T convert(Object fromInstance,
                            Class<T> toType)

Turn the passed in value to the class indicated. This will allow, for example, a String value to be passed in and have it coerced to a Long.

     Examples:
     Long x = convert("35", Long.class);
     Date d = convert("2015/01/01", Date.class)
     int y = convert(45.0, int.class)
     String date = convert(date, String.class)
     String date = convert(calendar, String.class)
     Short t = convert(true, short.class);     // returns (short) 1 or  (short) 0
     Long date = convert(calendar, long.class); // get calendar's time into long
 

Parameters:

fromInstance - A value used to create the targetType, even though it may not (most likely will not) be the same data type as the targetType

toType - Class which indicates the targeted (final) data type. Please note that in addition to the 8 Java primitives, the targeted class can also be Date.class, String.class, BigInteger.class, and BigDecimal.class. The primitive class can be either primitive class or primitive wrapper class, however, the returned value will always [obviously] be a primitive wrapper.

Returns:

An instanceof targetType class, based upon the value passed in.
