`EXCEPTION` Strategy where the cache will block new entries from being written if they would exceed the configured size
`FIFO` Deprecated.
`LIRS` Deprecated.
`LRU` Deprecated.
`MANUAL` Strategy where the cache does nothing but the user is assumed to manually invoke evict method
`NONE` Eviction Strategy where nothing is done by the cache and the user is probably not going to use eviction manually

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`boolean`	`isEnabled()` Whether or not the cache will do something due to the strategy
`boolean`	`isExceptionBased()` The cache will throw exceptions to prevent memory growth
`boolean`	`isRemovalBased()` The cache will remove other entries to make room to limit memory growth
`static EvictionStrategy`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static EvictionStrategy[]`	`values()` Returns an array containing the constants of this enum type, in the order they are declared.

- Method Detail
  - values
```
public static EvictionStrategy[] 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 (EvictionStrategy c : EvictionStrategy.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static EvictionStrategy 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
  - isEnabled
```
public boolean isEnabled()
```
    Whether or not the cache will do something due to the strategy
    
    Returns:
  - isExceptionBased
```
public boolean isExceptionBased()
```
    The cache will throw exceptions to prevent memory growth
    
    Returns:
  - isRemovalBased
```
public boolean isRemovalBased()
```
    The cache will remove other entries to make room to limit memory growth
    
    Returns:
