Method Detail

pop

java.util.Map<K,V> pop()

Do a 'pop' of the single tail dictionary. The caller is responsible for iterating it.

Returns:

null if no tail map present, otherwise a map with at least one item.

isIteratingActive

boolean isIteratingActive()

Reports if this dictionary has the "being iterated" flag.

Returns:

true if this dictionary is being iterated.

flagIterating

java.lang.AutoCloseable flagIterating()

The caller is responsible for setting the iterating active flag, by implementing a try(AutoCloseable obj = dict.FlagIterating()) block.

Returns:

A new AutoClosable object.
