类 DefaultContextCache

构造器详细资料

• DefaultContextCache

  public DefaultContextCache()

  Create a new DefaultContextCache using the maximum cache size obtained via ContextCacheUtils.retrieveMaxCacheSize().

  从以下版本开始:

  4.3

  DefaultContextCache(int), ContextCacheUtils.retrieveMaxCacheSize()

• DefaultContextCache

  public DefaultContextCache​(int maxSize)

  Create a new DefaultContextCache using the supplied maximum cache size.

  参数:

  maxSize - the maximum cache size

  抛出:

  IllegalArgumentException - if the supplied maxSize value is not positive

  从以下版本开始:

  4.3

方法详细资料

• contains

  public boolean contains​(MergedContextConfiguration key)

  Determine whether there is a cached context for the given key.

  指定者:

  contains 在接口中 ContextCache

  参数:

  key - the context key (never null)

  返回:

  true if the cache contains a context with the given key

• get

  @Nullable
  public ApplicationContext get​(MergedContextConfiguration key)

  Obtain a cached ApplicationContext for the given key.

  The hit and miss counts must be updated accordingly.

  指定者:

  get 在接口中 ContextCache

  参数:

  key - the context key (never null)

  返回:

  the corresponding ApplicationContext instance, or null if not found in the cache

  另请参阅:

  ContextCache.remove(org.springframework.test.context.MergedContextConfiguration, org.springframework.test.annotation.DirtiesContext.HierarchyMode)

• put

  public void put​(MergedContextConfiguration key,
                  ApplicationContext context)

  Explicitly add an ApplicationContext instance to the cache under the given key, potentially honoring a custom eviction policy.

  指定者:

  put 在接口中 ContextCache

  参数:

  key - the context key (never null)

  context - the ApplicationContext instance (never null)

• remove

  public void remove​(MergedContextConfiguration key,
                     @Nullable
                     DirtiesContext.HierarchyMode hierarchyMode)

  Remove the context with the given key from the cache and explicitly close it if it is an instance of ConfigurableApplicationContext.

  Generally speaking, this method should be called to properly evict a context from the cache (e.g., due to a custom eviction policy) or if the state of a singleton bean has been modified, potentially affecting future interaction with the context.

  In addition, the semantics of the supplied HierarchyMode must be honored. See the Javadoc for DirtiesContext.HierarchyMode for details.

  指定者:

  remove 在接口中 ContextCache

  参数:

  key - the context key; never null

  hierarchyMode - the hierarchy mode; may be null if the context is not part of a hierarchy

• size

  public int size()

  Determine the number of contexts currently stored in the cache.

  If the cache contains more than Integer.MAX_VALUE elements, this method must return Integer.MAX_VALUE.

  指定者:

  size 在接口中 ContextCache

• getMaxSize

  public int getMaxSize()

  Get the maximum size of this cache.

• getParentContextCount

  public int getParentContextCount()

  Determine the number of parent contexts currently tracked within the cache.

  指定者:

  getParentContextCount 在接口中 ContextCache

• getHitCount

  public int getHitCount()

  Get the overall hit count for this cache.

  A hit is any access to the cache that returns a non-null context for the queried key.

  指定者:

  getHitCount 在接口中 ContextCache

• getMissCount

  public int getMissCount()

  Get the overall miss count for this cache.

  A miss is any access to the cache that returns a null context for the queried key.

  指定者:

  getMissCount 在接口中 ContextCache

• reset

  public void reset()

  Reset all state maintained by this cache including statistics.

  指定者:

  reset 在接口中 ContextCache

  另请参阅:

  ContextCache.clear(), ContextCache.clearStatistics()

• clear

  public void clear()

  Clear all contexts from the cache, clearing context hierarchy information as well.

  指定者:

  clear 在接口中 ContextCache

• clearStatistics

  public void clearStatistics()

  Clear hit and miss count statistics for the cache (i.e., reset counters to zero).

  指定者:

  clearStatistics 在接口中 ContextCache

• logStatistics

  public void logStatistics()

  Log the statistics for this ContextCache at DEBUG level using the "org.springframework.test.context.cache" logging category.

  The following information should be logged.

  • name of the concrete ContextCache implementation
  • ContextCache.size()
  • parent context count
  • hit count
  • miss count
  • any other information useful for monitoring the state of this cache

  指定者:

  logStatistics 在接口中 ContextCache

• toString

  public String toString()

  Generate a text string containing the implementation type of this cache and its statistics.

  The string returned by this method contains all information required for compliance with the contract for logStatistics().

  覆盖:

  toString 在类中 Object

  返回:

  a string representation of this cache, including statistics
