Interface Spatial

All Known Implementing Classes:

SpatialKey

public interface Spatial

Interface Spatial represents boxes in 2+ dimensional space, where total ordering is not that straight-forward. They can be used as keys for MVRTree.

Method Summary

Modifier and Type	Method and Description
Spatial	clone(long id) Creates a copy of this Spatial object with different id.
boolean	equalsIgnoringId(Spatial o) Check whether two objects are equals, but do not compare the id fields.
long	getId() Get id of this Spatial object
boolean	isNull() Test whether this object has no value
float	max(int dim) Get the maximum value for the given dimension.
float	min(int dim) Get the minimum value for the given dimension.
void	setMax(int dim, float x) Set the maximum value for the given dimension.
void	setMin(int dim, float x) Set the minimum value for the given dimension.

Method Detail

min

float min(int dim)

Parameters:

dim - the dimension

Returns:

the value

setMax

void setMax(int dim,
            float x)

Set the maximum value for the given dimension.

Parameters:

dim - the dimension

x - the value

clone

Spatial clone(long id)

Creates a copy of this Spatial object with different id.

Parameters:

id - for the new Spatial object

Returns:

a clone

getId

long getId()

Get id of this Spatial object

Returns:

id

isNull

boolean isNull()

Test whether this object has no value

Returns:

true if it is NULL, false otherwise

equalsIgnoringId

boolean equalsIgnoringId(Spatial o)

Check whether two objects are equals, but do not compare the id fields.

Parameters:

o - the other key

Returns:

true if the contents are the same
