Interface LongProcedure

public interface LongProcedure

Interface that represents a procedure object: a procedure that takes a single argument and does not return a value.

apply

public boolean apply(long 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.
