- Method Detail
  - create
```
static ByteBufAllocatorBuilder create()
```
    Creates a new ByteBufAllocatorBuilder.
  - build
```
ByteBufAllocatorWithOomHandler build()
```
    Finalize the configured ByteBufAllocator.
  - pooledAllocator
```
ByteBufAllocatorBuilder pooledAllocator(io.netty.buffer.ByteBufAllocator pooledAllocator)
```
    Specify a custom allocator where the allocation requests should be forwarded to.
    Default is to use a new instance of PooledByteBufAllocator.
  - unpooledAllocator
```
ByteBufAllocatorBuilder unpooledAllocator(io.netty.buffer.ByteBufAllocator unpooledAllocator)
```
    Specify a custom allocator where the allocation requests should be forwarded to.
    Default is to use UnpooledByteBufAllocator.DEFAULT.
  - poolingPolicy
```
ByteBufAllocatorBuilder poolingPolicy(PoolingPolicy policy)
```
    Define the memory pooling policy.
    Default is PoolingPolicy.PooledDirect
  - poolingConcurrency
```
ByteBufAllocatorBuilder poolingConcurrency(int poolingConcurrency)
```
    Controls the amount of concurrency for the memory pool.
    Default is to have a number of allocator arenas equals to 2 * CPUS.
    Decreasing this number will reduce the amount of memory overhead, at the expense of increased allocation contention.
  - outOfMemoryPolicy
```
ByteBufAllocatorBuilder outOfMemoryPolicy(OutOfMemoryPolicy policy)
```
    Define the OutOfMemory handling policy.
    Default is OutOfMemoryPolicy.FallbackToHeap
  - outOfMemoryListener
```
ByteBufAllocatorBuilder outOfMemoryListener(java.util.function.Consumer<java.lang.OutOfMemoryError> listener)
```
    Add a listener that is triggered whenever there is an allocation failure.
    Application can use this to trigger alerting or process restarting.
  - leakDetectionPolicy
```
ByteBufAllocatorBuilder leakDetectionPolicy(LeakDetectionPolicy leakDetectionPolicy)
```
    Enable the leak detection for the allocator.
    Default is LeakDetectionPolicy.Disabled
