| Bytes |
Utility class that handles byte arrays, conversions to/from other types,
comparisons, hash code generation, manufacturing keys for HashMaps or
HashSets, etc. |
| Bytes.ByteArrayComparator |
Byte array comparator class. |
| Classes |
Utilities for class manipulation. |
| ClassSize |
Class for determining the "size" of a class, an attempt to calculate the
actual bytes that an object of this class will occupy in memory
The core of this class is taken from the Derby project |
| CollectionUtils |
Utility methods for dealing with Collections, including treating null collections as empty. |
| DefaultEnvironmentEdge |
