Class Summary

Modifier and Type	Class and Description
pack-priv class	Absent<T> Implementation of an `Optional` not containing a reference.
pack-priv abstract class	AbstractIterator<T extends @Nullable Object> Note this class is a copy of `com.google.common.collect.AbstractIterator` (for dependency reasons).
public class	Ascii Static methods pertaining to ASCII characters (those in the range of values `0x00` through `0x7F`), and to strings containing such characters.
public abstract class	CharMatcher Determines a true or false value for any Java `char` value, just as `Predicate` does for any `Object`.
public class	Charsets Contains constant definitions for the six standard `Charset` instances, which are guaranteed to be supported by all Java platform implementations.
pack-priv abstract class	CommonMatcher The subset of the `java.util.regex.Matcher` API which is used by this package, and also shared with the `re2j` library.
pack-priv abstract class	CommonPattern The subset of the `java.util.regex.Pattern` API which is used by this package, and also shared with the `re2j` library.
public abstract class	Converter<A, B> A function from `A` to `B` with an associated reverse function from `B` to `A`; used for converting back and forth between different representations of the same information.
public class	Defaults This class provides default values for all Java types, as defined by the JLS.
public class	Enums Utility methods for working with `Enum` instances.
public abstract class	Equivalence<T> A strategy for determining whether two instances are considered equivalent, and for computing hash codes in a manner consistent with that equivalence.
pack-priv abstract class	ExtraObjectsMethodsForWeb Holder for extra methods of `Objects` only in web.
public abstract class	FinalizablePhantomReference<T> Phantom reference with a `finalizeReferent()` method which a background thread invokes after the garbage collector reclaims the referent.
public class	FinalizableReferenceQueue A reference queue with an associated background thread that dequeues references and invokes `FinalizableReference#finalizeReferent()` on them.
public abstract class	FinalizableSoftReference<T> Soft reference with a `finalizeReferent()` method which a background thread invokes after the garbage collector reclaims the referent.
public abstract class	FinalizableWeakReference<T> Weak reference with a `finalizeReferent()` method which a background thread invokes after the garbage collector reclaims the referent.
pack-priv class	FunctionalEquivalence<F, T> Equivalence applied on functional result.
public class	Functions Static utility methods pertaining to `com.google.common.base.Function` instances; see that class for information about migrating to `java.util.function`.
pack-priv class	Internal This class is for `com.google.common.base` use only!
pack-priv class	Java8Compatibility Wrappers around `Buffer` methods that are covariantly overridden in Java 9+.
pack-priv class	JdkPattern A regex pattern implementation which is backed by the `Pattern`.
public class	Joiner An object which joins pieces of text (specified as an array, `Iterable`, varargs or even a `Map`) with a separator.
public class	MoreObjects Helper functions that operate on any `Object`, and are not already provided in `java.util.Objects`.
pack-priv class	NullnessCasts A utility method to perform unchecked casts to suppress errors produced by nullness analyses.
public class	Objects Helper functions that can operate on any `Object`.
public abstract class	Optional< the type of instance that can be contained. `Optional` is naturally covariant on this type, so it is safe to cast an `Optional<T>` to `Optional<S>` for any supertype `S` of `T`. T> An immutable object that may contain a non-null reference to another object.
pack-priv class	PairwiseEquivalence<E, T extends @Nullable E>
pack-priv class	Platform Methods factored out so that they can be emulated differently in GWT.
public class	Preconditions Static convenience methods that help a method or constructor check whether it was invoked correctly (that is, whether its preconditions were met).
public class	Predicates Static utility methods pertaining to `Predicate` instances.
pack-priv class	Present<T> Implementation of an `Optional` containing a reference.
pack-priv class	SmallCharMatcher An immutable version of CharMatcher for smallish sets of characters that uses a hash table with linear probing to check for matches.
public class	Splitter Extracts non-overlapping substrings from an input string, typically by recognizing appearances of a separator sequence.
public class	Stopwatch An object that accurately measures elapsed time: the measured duration between two successive readings of "now" in the same process.
public class	Strings Static utility methods pertaining to `String` or `CharSequence` instances.
public class	Suppliers Useful suppliers.
public class	Throwables Static utility methods pertaining to instances of `Throwable`.
public abstract class	Ticker A time source; returns a time value representing the number of nanoseconds elapsed since some fixed but arbitrary point in time.
public class	Utf8 Low-level, high-performance utility methods related to the UTF-8 character encoding.
public class	Verify Static convenience methods that serve the same purpose as Java language assertions, except that they are always enabled.
public class	VerifyException Exception thrown upon the failure of a verification check, including those performed by the convenience methods of the `Verify` class.

Modifier and Type	Enum and Description
public enum	CaseFormat Utility class for converting between various ASCII case formats.
public enum	StandardSystemProperty Represents a standard system property.
