Constructor Detail

HyperBoundingBox

public HyperBoundingBox()

Empty constructor for Externalizable interface.

HyperBoundingBox

public HyperBoundingBox(double[] min,
                double[] max)

Creates a HyperBoundingBox for the given hyper points.

Parameters:

min - - the coordinates of the minimum hyper point

max - - the coordinates of the maximum hyper point

HyperBoundingBox

public HyperBoundingBox(SpatialComparable other)

Constructor, cloning an existing spatial object.

Parameters:

other - Object to clone

Method Detail

getMin

public double getMin(int dimension)

Returns the coordinate at the specified dimension of the minimum hyper point.

Specified by:

getMin in interface SpatialComparable

Parameters:

dimension - the dimension for which the coordinate should be returned, where 0 ≤ dimension < this.getDimensionality()

Returns:

the coordinate at the specified dimension of the minimum hyper point

getMax

public double getMax(int dimension)

Returns the coordinate at the specified dimension of the maximum hyper point.

Specified by:

getMax in interface SpatialComparable

Parameters:

dimension - the dimension for which the coordinate should be returned, where 0 ≤ dimension < this.getDimensionality()

Returns:

the coordinate at the specified dimension of the maximum hyper point

getDimensionality

public int getDimensionality()

Returns the dimensionality of this HyperBoundingBox.

Specified by:

getDimensionality in interface SpatialComparable

Returns:

the dimensionality of this HyperBoundingBox

toString

public String toString()

Returns a String representation of the HyperBoundingBox.

Overrides:

toString in class Object

Returns:

a string representation of this hyper bounding box

toString

public String toString(String pre,
              NumberFormat nf)

Returns a String representation of the HyperBoundingBox.

Parameters:

nf - number format for output accuracy

pre - the prefix of each line

Returns:

a string representation of this hyper bounding box

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - the stream to write the object to

Throws:

IOException - Includes any I/O exceptions that may occur

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

Specified by:

readExternal in interface Externalizable

Parameters:

in - the stream to read data from in order to restore the object

Throws:

IOException - if I/O errors occur

ClassNotFoundException - If the class for an object being restored cannot be found.
