Method Detail

getNodeById

Node getNodeById(Long id)

Package method to find a node in the node pool by its id.

Parameters:

id - The id of the node to search for.

Returns:

The node referred to by the id, null if not found.

getNodeIdByString

Long getNodeIdByString(String str)

Package method to find a node id based on its string representation.

Parameters:

str - The string representation of a node.

Returns:

The id of the node with the given string.

getNodePoolValues

List<Map<Long,String>> getNodePoolValues()

Returns all the nodes in the node pool.

Returns:

The node pool.

getNewNodeId

Long getNewNodeId()

Returns a new node id.

Returns:

a new node id

clear

void clear()

Removes all entries from the nodepool.

registerNodePoolValues

void registerNodePoolValues(List<Map<Long,String>> values)

Registers a large number of nodes in ones go.

Parameters:

values - the map contains a list of longs to serialized nodes (as strings).

removeNode

Remove a node from the node pool.

Parameters:

value - the value to remove.

Returns:

null if not delete or the value.
