Method Detail

getLayerIds

public java.util.List<ObjectId> getLayerIds()

Get all the layer ids contained by this container node and all sub-nodes.

Returns:

getObjectId

public ObjectId getObjectId()

getParentId

public ObjectId getParentId()

getNumNodes

public int getNumNodes()

addNode

public void addNode(HRPlusNode node)

removeNode

getNodes

public java.util.List<HRPlusNode> getNodes()

allNodesContainLayerId

public boolean allNodesContainLayerId(ObjectId layerId)

Parameters:

layerId -

Returns:

true if every node in this container and below contains @param layerId

Parameters:

env -

getMBR

public Envelope getMBR()

Compute the minimum bounding rectangle for nodes in this tree.

Returns:

query

public void query(Envelope env,
         java.util.List<HRPlusNode> matches)

Search this container for nodes within the envelope @param env and recurse into their containers.

Parameters:

env -

matches - list of nodes across the entire tree that fit in this envelope

getType

public TYPE getType()

getId

public ObjectId getId()
