java.lang.RuntimeException
- on load error
-
toClass
public static java.lang.Class toClass(java.lang.String str, boolean resolve, java.lang.ClassLoader loader)
Return the class for the given string, correctly handling primitive types. If the given class loader is null, the context loader of the current thread will be used.- Throws:

-
parse
public static java.lang.Object parse(java.lang.String val, java.lang.Class type)
Returnval
as the type specified bytype
. Iftype
is a primitive, the primitive wrapper type is created and returned, andnull
s are converted to the Java default for the primitive type.- Parameters:
val
- The string value to parsetype
- The type to parse. This must be a primitive or a primitive wrapper, or one ofBigDecimal
,BigInteger
,String
,Date
.- Throws:
java.lang.IllegalArgumentException
- iftype
is not a supported type, or ifval
