Class PackedIndexSpaceID

java.lang.Object

edu.unh.sdb.common.SpaceID

edu.unh.sdb.datasource.IndexSpaceID

edu.unh.sdb.datasource.PackedIndexSpaceID

All Implemented Interfaces:

java.lang.Cloneable

public class PackedIndexSpaceID
extends IndexSpaceID
implements java.lang.Cloneable

This class implements the IndexSpaceID class using a single integer to represent the dimensions of the ID. The leftmost 2 bits are used to represent the dimensionality, which can range from 1 to 4.

packedID

protected int packedID

Constructor Detail

PackedIndexSpaceID

public PackedIndexSpaceID(int i)

Constructs a one dimensional PackedIndexSpaceID with axis value set to the argument.

PackedIndexSpaceID

public PackedIndexSpaceID(int i,
                  int j)

Constructs a two dimensional PackedIndexSpaceID with axis values set to the given values.

PackedIndexSpaceID

public PackedIndexSpaceID(int i,
                  int j,
                  int k)

Constructs a three dimensional PackedIndexSpaceID with axis values set to the given values.

PackedIndexSpaceID

public PackedIndexSpaceID(int[] axes)

Constructs a PackedIndexSpaceID with dimensionality matching the length of the parameter array. The axes will be set to the contents of the array.

PackedIndexSpaceID

public PackedIndexSpaceID(IndexSpaceID id)

Constructs a PackedIndexSpaceID from the contents of the IndexSpaceID argument. If the dimensionality of the argument is too large, an exception will be thrown.

Method Detail

copyID

public final IndexSpaceID copyID()

Return a copy of this IndexSpaceID.

Specified by:

copyID in class IndexSpaceID

clone

public java.lang.Object clone()

Return a copy of this IndexSpaceID.

Specified by:

clone in class SpaceID

assign

public final void assign(PackedIndexSpaceID id)

Set the axes of this id to the axes of the parameter id. The assign method may elect to refer to the data in the parameter id, and not make a copy of this information.

getCoord

public int getCoord(int axisnumber)

Get the value corresponding to the specified axis. If the specified axis is too large, a DimensionalityError is created.

Specified by:

getCoord in class IndexSpaceID

getCoords

public int[] getCoords(int[] coords)

Fill the array argument with the coordinate values for this ISID. For convenience, a reference to the argument array is returned.

Specified by:

getCoords in class IndexSpaceID

setCoord

public void setCoord(int axisnumber,
            int value)

Set the specified axis to the specified value. If the specified axis is too large, a DimensionalityError is created.

Overrides:

setCoord in class SpaceID

dim

public int dim()

Returns the dimensionality of this IndexSpaceID.

Specified by:

dim in class SpaceID

toString

public java.lang.String toString()

Return a String representing the object.

Overrides:

toString in class IndexSpaceID

main

public static void main(java.lang.String[] args)
