  - isStoreByValue
```
boolean isStoreByValue()
```
    Whether storeByValue true or storeByReference false. When true, both keys and values are stored by value.
    When false, both keys and values are stored by reference. Caches stored by reference are capable of mutation by any threads holding the reference. The effects are:
    - if the key is mutated, then the key may not be retrievable or removable
    - if the value is mutated, then all threads in the JVM can potentially observe those mutations, subject to the normal Java Memory Model rules.
    Storage by reference only applies to the local heap. If an entry is moved off heap it will need to be transformed into a representation. Any mutations that occur after transformation may not be reflected in the cache.
    When a cache is storeByValue, any mutation to the key or value does not affect the key of value stored in the cache.
    The default value is true.
    Returns:
