`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.

- 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<? extends K, ? extends V>), 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
