Method Detail

isDefined

public static boolean isDefined(Object obj)

Convenience method to find out if a variable is defined (not null). This helps particularly to check if a Boolean variable has been passed to the velocity context, since the #if( $boolean ) construct is only satisfied, if the value both exists and is true.

Parameters:

obj - any object

Returns:

true if the object is not null, false otherwise
