AbstractNode class abstract
A node of an {@link AbstractSTRtree}. A node is one of:
- empty
- an interior node containing child {@link AbstractNode}s
- a leaf node containing data items ({@link ItemBoundable}s).
@version 1.7

Constructors
- AbstractNode()
- Default constructor required for serialization.
- AbstractNode.withLevel(int level)
- Constructs an AbstractNode at the given level in the tree @param level 0 if this node is a leaf, 1 if a parent of a leaf, and so on; the root node will have the highest level

Methods
-
addChildBoundable(
Boundable childBoundable) → void - Adds either an AbstractNode, or if this is a leaf node, a data object (wrapped in an ItemBoundable)
-
computeBounds(
) → Object - Returns a representation of space that encloses this Boundable, preferably not much bigger than this Boundable's boundary yet fast to test for intersection with the bounds of other Boundables. The class of object returned depends on the subclass of AbstractSTRtree.
-
getBounds(
) → Object -
Gets the bounds of this node
override
-
getChildBoundables(
) → List - Returns either child {@link AbstractNode}s, or if this is a leaf node, real data (wrapped in {@link ItemBoundable}s).
-
getLevel(
) → int - Returns 0 if this node is a leaf, 1 if a parent of a leaf, and so on; the root node will have the highest level
-
isEmpty(
) → bool - Tests whether there are any {@link Boundable}s at this node.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
size(
) → int - Gets the count of the {@link Boundable}s at this node.
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
