AbstractNode class abstract

A node of an {@link AbstractSTRtree}. A node is one of:

A node stores the bounds of its children, and its level within the index tree.

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

bounds ↔ Object?: getter/setter pair
childBoundables ↔ List: getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
level ↔ int: getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

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.
