public class JxnParameterCheck
extends Object

Collection of static methods to test ...
... the result type of an expression: whatIs(expression) calls the matching of overloaded methods.
... if an argument value of given type matches a method parameter of type T : testT(value).
... the transfer of an argument value to a method parameter of type T : asT(value) (with possible implicit cast on method invocation).

Examples of use in JXN:

  
   #import static JxnParameterCheck
   
   i4 = 12345
    = 12345 (int)
   whatIs i4
    = int:12345 (java.lang.String)
   testDouble i4
    = double:12345.0 (java.lang.String)
   testLong i4
    = long:12345 (java.lang.String)
   testInt i4
    = int:12345 (java.lang.String)
   testShort i4  ! int:12345 fits into short
    = short:12345 (java.lang.String)
   testByte i4  ! int:12345 does not fit into byte
   ?          ^
   ? invokeMethod: identifier testByte( int ) undefined, wrong number of parameters or not public
   ! but:
   i4 = 123
    = 123 (int)
   testByte i4  ! int:123 fits into byte
    = byte:123 (java.lang.String)
   ! and:
   testInt 1.0  ! double:1.0 is not implicitly cast to int
   ?          ^
   ? invokeMethod: identifier testInt( double ) undefined, wrong number of parameters or not public
