Constructor Detail

SpatialKey

public SpatialKey(long id,
                  float... minMax)

Create a new key.

Parameters:

id - the id

minMax - min x, max x, min y, max y, and so on

SpatialKey

public SpatialKey(long id,
                  SpatialKey other)

Method Detail

min

public float min(int dim)

Description copied from interface: Spatial

Get the minimum value for the given dimension.

Specified by:

min in interface Spatial

Parameters:

dim - the dimension

Returns:

the value

setMin

public void setMin(int dim,
                   float x)

Description copied from interface: Spatial

Set the minimum value for the given dimension.

Specified by:

setMin in interface Spatial

Parameters:

dim - the dimension

x - the value

max

public float max(int dim)

Description copied from interface: Spatial

Get the maximum value for the given dimension.

Specified by:

max in interface Spatial

Parameters:

dim - the dimension

Returns:

the value

setMax

public void setMax(int dim,
                   float x)

Description copied from interface: Spatial

Set the maximum value for the given dimension.

Specified by:

setMax in interface Spatial

Parameters:

dim - the dimension

x - the value

clone

public Spatial clone(long id)

Description copied from interface: Spatial

Creates a copy of this Spatial object with different id.

Specified by:

clone in interface Spatial

Parameters:

id - for the new Spatial object

Returns:

a clone

getId

public long getId()

Description copied from interface: Spatial

Get id of this Spatial object

Specified by:

getId in interface Spatial

Returns:

id

isNull

public boolean isNull()

Description copied from interface: Spatial

Test whether this object has no value

Specified by:

isNull in interface Spatial

Returns:

true if it is NULL, false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class Value

hashCode

public int hashCode()

Specified by:

hashCode in class Value

equals

public boolean equals(java.lang.Object other)

Description copied from class: Value

Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.

Specified by:

equals in class Value

Parameters:

other - the other value

Returns:

true if they are equal

compareTypeSafe

public int compareTypeSafe(Value v,
                           CompareMode mode,
                           CastDataProvider provider)

Description copied from class: Value

Compare this value against another value given that the values are of the same data type.

Specified by:

compareTypeSafe in class Value

Parameters:

v - the other value

mode - the compare mode

provider - the cast information provider

Returns:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

equalsIgnoringId

public boolean equalsIgnoringId(Spatial o)

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

Specified by:

equalsIgnoringId in interface Spatial

Parameters:

o - the other key

Returns:

true if the contents are the same
