- Method Detail
  - getBytes
```
int getBytes(long address,
             byte[] buffer,
             int offset,
             int length)
      throws MemoryFault
```
    Reads data from the memory range
    
    Parameters:
    
    address - Starting address
    
    buffer - Buffer to read into
    
    offset - Offset in buffer to write to
    
    length - Number of bytes to read
    
    Returns:
    
    Bytes read
    
    Throws:
    
    MemoryFault
  - isBacked
```
boolean isBacked()
```
    Specified by:
    
    isBacked in interface IMemoryRange
    
    Returns:
    
    True if this memory range is backed with data (such that getBytes() won't always throw MemoryFault).
