方法详细资料

build

public <K1 extends K,V1 extends V> ExpiringMap<K1,V1> build()

Builds and returns an expiring map.

类型参数:

K1 - Key type

V1 - Value type

返回:

K1,V1

expiration

public ExpiringMap.Builder<K,V> expiration(long duration,
                                           java.util.concurrent.TimeUnit timeUnit)

Sets the default map entry expiration.

参数:

duration - the length of time after an entry is created that it should be removed

timeUnit - the unit that duration is expressed in

返回:

Builder

抛出:

java.lang.NullPointerException - if timeUnit is null

maxSize

public ExpiringMap.Builder<K,V> maxSize(int maxSize)

Sets the maximum size of the map. Once this size has been reached, adding an additional entry will expire the first entry in line for expiration based on the expiration policy.

参数:

maxSize - The maximum size of the map.

返回:

Builder

entryLoader

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> entryLoader(EntryLoader<? super K1,? super V1> loader)

Sets the EntryLoader to use when loading entries. Either an EntryLoader or ExpiringEntryLoader may be set, not both.

类型参数:

K1 - K1

V1 - V1

参数:

loader - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if loader is null

java.lang.IllegalStateException - if an ExpiringEntryLoader is set

expiringEntryLoader

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> expiringEntryLoader(ExpiringEntryLoader<? super K1,? super V1> loader)

Sets the ExpiringEntryLoader to use when loading entries and configures variable expiration. Either an EntryLoader or ExpiringEntryLoader may be set, not both.

类型参数:

K1 - K1

V1 - V1

参数:

loader - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if loader is null

java.lang.IllegalStateException - if an EntryLoader is set

expirationListener

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> expirationListener(ExpirationListener<? super K1,? super V1> listener)

Configures the expiration listener that will receive notifications upon each map entry's expiration. Notifications are delivered synchronously and block map write operations.

类型参数:

K1 - K1

V1 - V1

参数:

listener - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if listener is null

expirationListeners

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> expirationListeners(java.util.List<ExpirationListener<? super K1,? super V1>> listeners)

Configures the expiration listeners which will receive notifications upon each map entry's expiration. Notifications are delivered synchronously and block map write operations.

类型参数:

K1 - K1

V1 - V1

参数:

listeners - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if listener is null

asyncExpirationListener

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> asyncExpirationListener(ExpirationListener<? super K1,? super V1> listener)

Configures the expiration listener which will receive asynchronous notifications upon each map entry's expiration.

类型参数:

K1 - K1

V1 - V1

参数:

listener - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if listener is null

asyncExpirationListeners

public <K1 extends K,V1 extends V> ExpiringMap.Builder<K1,V1> asyncExpirationListeners(java.util.List<ExpirationListener<? super K1,? super V1>> listeners)

Configures the expiration listeners which will receive asynchronous notifications upon each map entry's expiration.

类型参数:

K1 - K1

V1 - V1

参数:

listeners - to set

返回:

K1,V1

抛出:

java.lang.NullPointerException - if listener is null

expirationPolicy

public ExpiringMap.Builder<K,V> expirationPolicy(ExpirationPolicy expirationPolicy)

Configures the map entry expiration policy.

参数:

expirationPolicy - ExpirationPolicy

返回:

Builder

抛出:

java.lang.NullPointerException - if expirationPolicy is null

variableExpiration

public ExpiringMap.Builder<K,V> variableExpiration()

Allows for map entries to have individual expirations and for expirations to be changed.

返回:

Builder
