Method Detail

isValid

public static boolean isValid(Object param,
                              Class paramType)

Checks whether the parameter passed in is of the required type and is not null.

Parameters

param - Paramerter to be checked for validity.

paramType - Type the above parameter should be to pass the test.

Returns

true if parameter is of required type and not null

isNotNull

public static boolean isNotNull(Object param)

Checks whether the parameter passed in is null.

Parameters

param - Paramerter to be checked for nullness

Returns

false if parameter is null

isInRange
