```
public class MemoryLimits
extends java.lang.Object
```
A last resort hardening against memory overuse. This is used to stop the propagation of obviously abnormal data sizes that would indicate an obvious denial of service attack. This class can be reimplemented to be platform sensitive, eg. by checking the sizes against remaining free memory. The different checks are to differentiate for likely maximum memory usage patterns for the different use cases, but they should be kept reasonably high and they should not do any validation or check beyond simple size limits, those checks are to be done elsewhere.
