Interface SpatialQuery

All Known Implementing Classes:

BasicSpatialQuery

public interface SpatialQuery

Interface defining the operations required for spatial queries performed by a spatial search tree.

Method Summary

boolean	areEqual(SpatialSearchTreeObject queryObj, SpatialSearchTreeObject storedObj) Tests whether the query object and the stored object are equal.
boolean	conditionFulfilled(MBR rect, MBR entryMBR) Tests whether the query rectangle and the MBR of a non-leaf entry fulfill the query condition.
boolean	conditionFulfilled(MBR rect, SpatialSearchTreeEntry entry) Tests whether the query rectangle and an leaf entry fulfill the query condition.
boolean	conditionFulfilled(MBR rect, SpatialSearchTreeObject obj) Tests whether the query rectangle and an object fulfill the query condition.

Method Detail

areEqual

public boolean areEqual(SpatialSearchTreeObject queryObj,
                        SpatialSearchTreeObject storedObj)

Tests whether the query object and the stored object are equal.

Parameters:

queryObj - the query object

storedObj - the stored object

Returns:

true if equal

conditionFulfilled

public boolean conditionFulfilled(MBR rect,
                                  MBR entryMBR)

Tests whether the query rectangle and the MBR of a non-leaf entry fulfill the query condition.

Parameters:

rect - the query rectangle

entryMBR - the minimum bounding rectangle of non-leaf entry

Returns:

true if the condition is fulfilled

conditionFulfilled

public boolean conditionFulfilled(MBR rect,
                                  SpatialSearchTreeEntry entry)

Tests whether the query rectangle and an leaf entry fulfill the query condition.

Parameters:

rect - the query rectangle

entry - the entry of a leaf entry

Returns:

true if the condition is fulfilled

conditionFulfilled

public boolean conditionFulfilled(MBR rect,
                                  SpatialSearchTreeObject obj)

Tests whether the query rectangle and an object fulfill the query condition.

Parameters:

rect - the query rectangle

obj - the object

Returns:

true if the condition fulfilled
