Deprecated Interfaces

Interface and Description

com.google.common.util.concurrent.CheckedFuture CheckedFuture cannot properly support the chained operations that are the primary goal of ListenableFuture. CheckedFuture also encourages users to rethrow exceptions from one thread in another thread, producing misleading stack traces. Additionally, it has a surprising policy about which exceptions to map and which to leave untouched. Guava users who want a CheckedFuture can fork the classes for their own use, possibly specializing them to the particular exception type they use. We recommend that most people use ListenableFuture and perform any exception wrapping themselves. This class is scheduled for removal from Guava in February 2018.

Deprecated Classes

Class and Description
com.google.common.util.concurrent.AbstractCheckedFuture CheckedFuture cannot properly support the chained operations that are the primary goal of ListenableFuture.
