  - isNioRam
```
public boolean isNioRam()

    Return if the journal will use off-heap buffers (NIO RAM) instead of on-heap buffers (byte arrays).
    
    Specified by:
    
    isNioRam in interface RamJournalRM.Dependencies
    
    Returns:
    
    true if the journal is configured to use NIO "direct buffer" RAM

    Set the journal to use direct buffers (NIO RAM) versus on-heap buffers (byte arrays) to store the journal data. The default is that the journal data is kept on heap in byte arrays.
    
    Parameters:
    
    fUseNioRam - pass true to use NIO direct buffers off the heap, or false to use byte arrays on the heap

    this object
  - getMaxPoolSize
```
public long getMaxPoolSize()
```
    Return the maximum size (in bytes) of the buffers that can be held by the pool. This is not a limit of how many buffers can be allocated, since some may be in use at any time, but rather how many will be held by the pool (i.e. recycled) as they are released.
    
    Specified by:

  - setMaxPoolSize
```
public RamJournalRM.DefaultDependencies setMaxPoolSize(long maxPool)
