GraphContainerProvider (OpenNMS 28.0.0-SNAPSHOT API)

All Known Implementing Classes:

GraphmlGraphContainerProvider, PersistenceGraphContainerProvider, SingleGraphContainerProvider
```
public interface GraphContainerProvider
```
A GraphContainerProvider is responsible for providing an ImmutableGraphContainer as well as the meta information of that container. If possible the implementators should not load the full container when getContainerInfo() is invoked.

Method Summary

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

- Method Detail
  - loadGraphContainer
```
ImmutableGraphContainer loadGraphContainer()
```
    Returns a fully loaded ImmutableGraphContainer object, containing ALL vertices and edges. May be slow.
    
    Returns:
    
    The populated container
  - getContainerInfo
```
GraphContainerInfo getContainerInfo()
```
    Invoking 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 getContainerInfo() should return very quickly with the meta data of the container and its graphs.
    
    Returns:
    
    The container's meta data
