Detailed Description

A static index on a set of 1-dimensional intervals, using an R-Tree packed based on the order of the interval midpoints.

It supports range searching, where the range is an interval of the real line (which may be a single point). A common use is to index 1-dimensional intervals which are the projection of 2-D objects onto an axis of the coordinate system.

This index structure is static

void geos::index::intervalrtree::SortedPackedIntervalRTree::insert ( double  min,
double  max,
void *  item 
)

Adds an item to the index which is associated with the given interval

Parameters:
min the lower bound of the item interval
max the upper bound of the item interval
item the item to insert, ownership left to caller
Exceptions:
IllegalStateException if the index has already been queried
void geos::index::intervalrtree::SortedPackedIntervalRTree::query ( double  min,
double  max,
index::ItemVisitor visitor 
)

Search for intervals in the index which intersect the given closed interval and apply the visitor to them.

Parameters:
min the lower bound of the query interval
max the upper bound of the query interval
visitor the visitor to pass any matched items to
