Deprecated Classes

Class and Description
com.google.common.collect.ForwardingBlockingDeque This class has moved to com.google.common.util.concurrent. Please use ForwardingBlockingDeque instead.
com.google.common.collect.TreeTraverser Use Traverser instead. All instance methods have their equivalent on the result of Traverser.forTree(tree) where tree implements SuccessorsFunction, which has a similar API as TreeTraverser.children(T) or can be the same lambda function as passed into TreeTraverser.using(Function). This class is scheduled to be removed in October 2019.

Deprecated Exceptions

Exceptions and Description

com.google.common.collect.ComputationException This exception is no longer thrown by com.google.common. Previously, it was thrown by MapMaker computing maps. When support for computing maps was removed from MapMaker, it was added to CacheBuilder, which throws ExecutionException, UncheckedExecutionException, and ExecutionError. Any code that is still catching ComputationException may need to be updated to catch some of those types instead. (Note that this type, though deprecated, is not planned to be removed from Guava.)

For speed: Hashing.goodFastHash(int), though see its docs for caveats.

For speed: Hashing.goodFastHash(int), though see its docs for caveats.
