BackgroundMemoryList

Type Parameters:

V - Value type of the measurements to be stored. Most often used values are Double or Long

Q - Quantity to be stored, see Quantity

All Superinterfaces:

BinaryMeasurementsList<V,Q>, Collection<javax.measure.Measure<V,Q>>, Iterable<javax.measure.Measure<V,Q>>, List<javax.measure.Measure<V,Q>>

All Known Implementing Classes:

BackgroundMemoryListImpl
```
public interface BackgroundMemoryList<V,Q extends javax.measure.quantity.Quantity>
extends BinaryMeasurementsList<V,Q>
```
Interface of a @link BinaryMeasurementsList list, which uses a file on a drive as efficient background storage, i.e., it consumes constant main memory so that it can store huge amounts of list entries.

  - open
```
void open()
   throws IOException
```
    Opens the link to the file on background storage. Only allowed if there is no open link.
    
    Throws:
    
    IOException - Thrown if file IO fails.
  - close
```
void close()
    throws IOException
```
    Closes the link to the file on background storage. There are no further add or get operations allowed after closing.
    
    Throws:
    
    IOException
  - isClosed
```
boolean isClosed()
```
    Get the status of the link to the attached file. Any read or write operation is only allowed in open state.
    
    Returns:
    
    true if the link to the attached file is closed.
  - flush
```
void flush()
    throws IOException
```
    Throws:
    
    IOException
