Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`cacheNodes(List<NodeRef> nodeRefs)`	Pre-cache data relevant to the given nodes.
`void`	`cacheNodesById(List<Long> nodeIds)`	Pre-cache data relevant to the given nodes.
`void`	`clear()`	FOR TESTING ONLY: Clears out node cache data
`Set<Long>`	`getCachedAncestors(List<Long> nodeIds)`	Gets the current set of cached ancestors of the given list of nodes.
`void`	`setCheckNodeConsistency()`	Transaction-scope setting to make the Node loader to guarantee the validity of all caches: some cache data will be reloaded; some cache data will be considered safe.

- Method Detail
  - getCachedAncestors
```
Set<Long> getCachedAncestors(List<Long> nodeIds)
```
    Gets the current set of cached ancestors of the given list of nodes.
    
    Parameters:
    
    nodeIds - a list of node IDs to visit
    
    Returns:
    
    the current set of cached ancestors of the given list of nodes, including the nodes themselves.
  - setCheckNodeConsistency
```
void setCheckNodeConsistency()
```
    Transaction-scope setting to make the Node loader to guarantee the validity of all caches: some cache data will be reloaded; some cache data will be considered safe.
  - cacheNodes
```
void cacheNodes(List<NodeRef> nodeRefs)
```
    Pre-cache data relevant to the given nodes. There is no need to split the collection up before calling this method; it is up to the implementations to ensure that batching is done where necessary.
    
    Parameters:
    
    nodeRefs - the nodes that will be cached.
  - cacheNodesById
```
void cacheNodesById(List<Long> nodeIds)
```
    Pre-cache data relevant to the given nodes. There is no need to split the collection up before calling this method; it is up to the implementations to ensure that batching is done where necessary.
    
    Parameters:
    
    nodeIds - the nodes that will be cached.
  - clear
```
void clear()
```
    FOR TESTING ONLY: Clears out node cache data
