Method Detail

apply

boolean apply(ObjectMatrix2D element)
Applies a procedure to an argument. Optionally can return a boolean flag to inform the object calling the procedure.

Example: forEach() methods often use procedure objects. To signal to a forEach() method whether iteration should continue normally or terminate (because for example a matching element has been found), a procedure can return false to indicate termination and true to indicate continuation.

Parameters:
element - element passed to the procedure.
Returns:
a flag to inform the object calling the procedure.
