|
| BufferAllocator |
Wrapper class to deal with byte buffer allocation.

|
| ArrowByteBufAllocator |

|
| BaseAllocator | |
| BoundsChecking | |
| LowCostIdentityHashMap<K,V extends ValueWithKeyIncluded<K>> |

Map APIs
It incurs low initial cost (just two elements by default)
It assumes Value includes the Key - Implements @ValueWithKeyIncluded iface
that provides "getKey" method
|
