Method Summary

Modifier and Type	Method	Description
static <T> Recycler<T>	concurrent(Recycler.Factory<T> factory)
static <T> Recycler<T>	concurrent(Recycler.Factory<T> factory, int concurrencyLevel)	Create a concurrent implementation that can support concurrent access from concurrencyLevel threads with little contention.
static <T> Recycler<T>	concurrentDeque(Recycler.C<T> c, int limit)	Return a concurrent recycler based on a deque.
static <T> Recycler<T>	deque(Recycler.C<T> c, int limit)	Return a recycler based on a deque.
static <T> Recycler.Factory<T>	dequeFactory(Recycler.C<T> c, int limit)	Return a recycler based on a deque.
static <T> Recycler<T>	locked(Recycler<T> recycler)	Wrap the provided recycler so that calls to Recycler.obtain() and Releasable.close() are protected by a lock.
static <T> Recycler<T>	none(Recycler.C<T> c)	Return a Recycler that never recycles entries.
static <T> Recycler<T>	sizing(Recycler<T> defaultRecycler, Recycler<T> smallObjectRecycler, int minSize)	Wrap two recyclers and forward to calls to smallObjectRecycler when size < minSize and to defaultRecycler otherwise.
static Recyclers	valueOf(java.lang.String name)	Returns the enum constant of this type with the specified name.
static Recyclers[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static Recyclers[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Recyclers c : Recyclers.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Recyclers valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

none

public static <T> Recycler<T> none(Recycler.C<T> c)

Return a Recycler that never recycles entries.

concurrentDeque

public static <T> Recycler<T> concurrentDeque(Recycler.C<T> c,
                                              int limit)

Return a concurrent recycler based on a deque.

deque

public static <T> Recycler<T> deque(Recycler.C<T> c,
                                    int limit)

Return a recycler based on a deque.

dequeFactory

public static <T> Recycler.Factory<T> dequeFactory(Recycler.C<T> c,
                                                   int limit)

Return a recycler based on a deque.

sizing

public static <T> Recycler<T> sizing(Recycler<T> defaultRecycler,
                                     Recycler<T> smallObjectRecycler,
                                     int minSize)

Wrap two recyclers and forward to calls to smallObjectRecycler when size < minSize and to defaultRecycler otherwise.

locked

public static <T> Recycler<T> locked(Recycler<T> recycler)

Wrap the provided recycler so that calls to Recycler.obtain() and Releasable.close() are protected by a lock.

concurrent

public static <T> Recycler<T> concurrent(Recycler.Factory<T> factory,
                                         int concurrencyLevel)

Create a concurrent implementation that can support concurrent access from concurrencyLevel threads with little contention.
