    public enum RemovalCause

extends Enum<RemovalCause>

The reason why a cached entry was removed.

  10.0

Enum Constant Summary
`COLLECTED` The entry was removed automatically because its key or value was garbage-collected.
`EXPIRED` The entry's expiration timestamp has passed.
`EXPLICIT` The entry was manually removed by the user.
`REPLACED` The entry itself was not actually removed, but its value was replaced by the user.
`SIZE` The entry was evicted due to size constraints.

Method Summary
`static RemovalCause` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
`static RemovalCause[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

### EXPLICIT

    public static final RemovalCause EXPLICIT

  The entry was manually removed by the user. This can result from the user invoking `Cache.invalidate(java.lang.Object)`, `Cache.invalidateAll(Iterable)`, `Cache.invalidateAll()`, `Map.remove(java.lang.Object)`, `ConcurrentMap.remove(java.lang.Object, java.lang.Object)`, or `Iterator.remove()`.

### REPLACED

    public static final RemovalCause REPLACED

  The entry itself was not actually removed, but its value was replaced by the user. This can result from the user invoking `Cache.put(K, V)`, `LoadingCache.refresh(K)`, `Map.put(K, V)`, `Map.putAll(java.util.Map)`, `ConcurrentMap.replace(Object, Object)`, or `ConcurrentMap.replace(Object, Object, Object)`.

### COLLECTED

    public static final RemovalCause COLLECTED

  The entry was removed automatically because its key or value was garbage-collected. This can occur when using `CacheBuilder.weakKeys()`, `CacheBuilder.weakValues()`, or `CacheBuilder.softValues()`.

### EXPIRED

    public static final RemovalCause EXPIRED

  The entry's expiration timestamp has passed. This can occur when using `CacheBuilder.expireAfterWrite(long, java.util.concurrent.TimeUnit)` or `CacheBuilder.expireAfterAccess(long, java.util.concurrent.TimeUnit)`.

### SIZE

    public static final RemovalCause SIZE

  The entry was evicted due to size constraints. This can occur when using `CacheBuilder.maximumSize` or `CacheBuilder.maximumWeight`.

Method Detail

### values

    public static RemovalCause[] 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 (RemovalCause c : RemovalCause.values())
          System.out.println(c);

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

### valueOf

    public static RemovalCause valueOf(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:
    `IllegalArgumentException` - if this enum type has no constant with the specified name
    `NullPointerException` - if the argument is null
