Method Detail

insert

public boolean insert(Envelope envelope,
                      T object)

insert in class QTree<T extends PositionableModel>

Parameters:

envelope - of the object

object - to insert

Returns:

true if the object was inserted, false otherwise.

insert

public boolean insert(T object)

Parameters:

object - to insert

Returns:

true if the object was inserted, false otherwise.

createNode

protected QTModelScene<T> createNode(int son)

Overrides:

createNode in class QTree<T extends PositionableModel>

Parameters:

son - one of QTree.LOWER_LEFT,QTree.LOWER_RIGHT,QTree.UP_LEFT,QTree.UP_RIGHT

Returns:

a new QTree created from the given index.

getObjects

public Set<T> getObjects(ViewParams viewParams)

Parameters:

viewParams - to get the objects for.

Returns:

the objects which intersect with the given view parameters and or it's children, or the empty list.

contains

Parameters:

object -

Returns:

true if this tree contains the given object

getMaxPixelError

public final double getMaxPixelError()

Returns:

the configured max pixel error.
