Significant API additions and changes

common.base

  • MoreObjects
    • Methods in Objects which do not have equivalents in java.util.Objects have been moved to MoreObjects to allow importing of both classes. Those methods have been deprecated in our Objects class. Methods which do have equivalents in java.util.Objects will remain (undeprecated) in our Objects class as long as Guava continues to support JDK 6.
  • Enums- removed deprecatedvalueOfFunction` method.

common.collect

  • FluentIterable.of(E[])
  • FluentIterable.append(E...)
  • FluentIterable.append(Iterable<? extends E>)
  • FluentIterable.join(Joiner)

common.hash

  • Hashing.crc32c()

BloomFilter no longer recognizes the system property com.google.common.hash.BloomFilter.useMitz32 (see Release 17 - A note on BloomFilter for more information).

common.io

Methods which took an InputSupplier or OutputSupplier parameter or which returned an InputSupplier or OutputSupplier (all of which were deprecated in Guava 15.0) have been removed. Additionally, ByteSource, ByteSink, CharSource and CharSink no longer implement InputSupplier or OutputSupplier.

The InputSupplier and OutputSupplier interfaces, which no longer have any usages in Guava, will be deleted in December 2015.

common.net

  • InetAddresses.decrement(InetAddress)

common.reflect

  • Parameter.getAnnotationsByType(Class<A>)
  • Parameter.getDeclaredAnnotation(Class<A>)
  • Parameter.getDeclaredAnnotationsByType(Class<A>)

common.util.concurrent

  • MoreExecutors.directExecutor() - lightweight, simple Executor that runs tasks on the thread that invokes execute.
  • MoreExecutors.newDirectExecutorService() - heavier ListeningExecutorService implementation of the same thing; equivalent to sameThreadExecutor(), which has been deprecated.
