Class SimpleMBR

java.lang.Object

org.khelekore.prtree.SimpleMBR

All Implemented Interfaces:

MBR

public class SimpleMBR
extends Object
implements MBR

An implementation of MBRND that keeps a double array with the max and min values

Please note that you should not normally use this class when PRTree wants a MBR since this will actually use a lot of extra memory.

Constructor Detail

SimpleMBR

public SimpleMBR(double... values)

Create a new SimpleMBR using the given double values for max and min. Note that the values should be stored as min, max, min, max.

Parameters:

values - the min and max values for each dimension.

SimpleMBR

public SimpleMBR(T t,
                 MBRConverter<T> converter)

Create a new SimpleMBR from a given object and a MBRConverter

Parameters:

t - the object to create the bounding box for

converter - the actual MBRConverter to use

public MBR union(MBR mbr)

Description copied from interface: MBR

Return a new MBR that is the union of this mbr and the other

Specified by:

union in interface MBR

Parameters:

mbr - the MBR to create a union with

Returns:

the new MBR

intersects

public boolean intersects(MBR other)

Description copied from interface: MBR

Check if the other MBR intersects this one

Specified by:

intersects in interface MBR

Parameters:

other - the MBR to check against

Returns:

true if the given MBR intersects with this MBR

intersects

public <T> boolean intersects(T t,
                              MBRConverter<T> converter)

Description copied from interface: MBR

Specified by:

intersects in interface MBR

Type Parameters:

T - the object type

Parameters:

t - a rectangular object

converter - the MBRConverter

Returns:

true if the given MBR intersects with the given object
