Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected static GraphContainerInfo`	`createContainerInfo()`
`GraphContainerInfo`	`getContainerInfo()`	Invoking `GraphContainerProvider.loadGraphContainer()` may take some time, so it is not feasible to invoke it, if only the meta data of the container is requested.
`void`	`init()`
`ImmutableGraphContainer`	`loadGraphContainer()`	Returns a fully loaded `ImmutableGraphContainer` object, containing ALL vertices and edges.

  - loadGraphContainer
```
public ImmutableGraphContainer loadGraphContainer()
```
    Description copied from interface: GraphContainerProvider
    
    Returns a fully loaded ImmutableGraphContainer object, containing ALL vertices and edges. May be slow.
    
    Specified by:
    
    loadGraphContainer in interface GraphContainerProvider
    
    Returns:
    
    The populated container
  - getContainerInfo
```
public GraphContainerInfo getContainerInfo()
```
    Description copied from interface: GraphContainerProvider
    
    Invoking GraphContainerProvider.loadGraphContainer() may take some time, so it is not feasible to invoke it, if only the meta data of the container is requested. Therefore the GraphContainerProvider.getContainerInfo() should return very quickly with the meta data of the container and its graphs.
    
    Specified by:
    
    getContainerInfo in interface GraphContainerProvider
    
    Returns:
    
    The container's meta data
  - init
```
public void init()
```
  - createContainerInfo
```
protected static GraphContainerInfo createContainerInfo()
```
