Method Details

removeOneOrNop

default boolean removeOneOrNop(T value)

Description copied from interface: IMemory

Removes one occurrence of the given value from the memory, if possible.

Memory is unchanged and false is returned if IMultiset or ISetMemory and value had no occurrences in the memory

Specified by:

removeOneOrNop in interface IMemory<T>

Returns:

true if this was the the last occurrence of the value, or (in case of IDeltaBag) is the first negative occurrence of the value
