Method Detail

forEachSegmentEntry

void forEachSegmentEntry(Consumer<? super E> action)

Performs the given action for each present entry in this segment until all entries have been processed or the action throws an Exception. Exceptions thrown by the action are relayed to the caller.

Parameters:

action - the action to be performed for each entry in this segment

forEachSegmentEntryWhile

boolean forEachSegmentEntryWhile(Predicate<? super E> predicate)

Checks the given predicate on each present entry in this segment until all entries have been processed or the predicate returns false for some entry, or throws an Exception. Exceptions thrown by the predicate are relayed to the caller.

If this segment is empty (i. e. size() call returns 0), this method returns true immediately.

Parameters:

predicate - the predicate to be checked for each entry in this segment

Returns:

true if the predicate returned true for all checked entries, false if it returned false for some entry

size

long size()

Returns the number of present entries in this segment.
