Detailed Description

A node of the STR tree.

Member Function Documentation

◆ addChildNode()

void geos::index::strtree::SimpleSTRnode::addChildNode ( SimpleSTRnode * childNode)

Adds either an AbstractNode, or if this is a leaf node, a data object (wrapped in an ItemBoundable)

◆ getBounds()

const void * geos::index::strtree::SimpleSTRnode::getBounds ( ) const
inlineoverridevirtual

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.

Returns
an Envelope (for STRtrees), an Interval (for SIRtrees), or other object (for other subclasses of AbstractSTRtree)
See also
AbstractSTRtree::IntersectsOp

Reimplemented from geos::index::strtree::ItemBoundable.

◆ getEnvelope()

const geom::Envelope & geos::index::strtree::SimpleSTRnode::getEnvelope ( ) const
inline

Returns a representation of space that encloses this Node

◆ getLevel()

std::size_t geos::index::strtree::SimpleSTRnode::getLevel ( ) const
inline

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

◆ isLeaf()

bool geos::index::strtree::SimpleSTRnode::isLeaf ( ) const
inlineoverridevirtual
