Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

- Method Detail
  - request
```
WritableMemory request(WritableMemory currentWritableMemory,
                       long capacityBytes)
```
    Request new WritableMemory with the given capacity. The current Writable Memory will be used to determine the byte order of the returned WritableMemory and other checks.
    
    Parameters:
    
    currentWritableMemory - the current writableMemory of the client. It must be non-null.
    
    capacityBytes - The capacity being requested. It must be ≥ 0.
    
    Returns:
    
    new WritableMemory with the given capacity.
  - requestClose
```
void requestClose(WritableMemory memToClose,
                  WritableMemory newMemory)
```
    Request close the AutoCloseable resource. This only applies to resources allocated using WritableMemory.allocateDirect(...). This may be ignored depending on the application implementation.
    
    Parameters:
    
    memToClose - the relevant WritbleMemory to be considered for closing. It must be non-null.
    
    newMemory - the newly allocated WritableMemory. It must be non-null. This is returned from the client to facilitate tracking for the convenience of the resource owner.
