      edu.unh.sdb.datasource.ISBounds

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

ISBoundsIterator

public class ISBounds
extends Bounds
implements java.lang.Cloneable, java.io.Serializable

The ISBounds class is meant to represent hypercubic subregions in an n-dimensional index space. Typically, a lower and upper corner point are given to the constructor, although it is also possible to just specify the dimensions of the subregion, yielding an ISBounds of the proper size situated at the origin. The dimensionality of an ISBounds is taken from the dimensionality of the corner points, which are assumed to match.

Return the length of the axis specified as an argument.

project

public ISBounds project(int axis)

Returns a new ISBounds which is the projection of this ISBounds onto a plane orthogonal to the specified axis.

Returns a new ISBounds which is a slice of this ISBounds of thickness 1 in a plane orthogonal to the specified axis, having the given coordinate value for that axis. The dimensionality of the result matches the dimensionality of this ISBounds, as long as the axis is valid for this ISBounds. If the specified axis is not valid, then an error is created.

The two argument bounds are set to represent two portions of this ISBounds split by a plane orthogonal to the splitAxis, at the coordinate value contained in splitAxisCoord. This coordinate value must be equal to or greater than the lower bound of this object in the split axis, and less than the upper bound. Otherwise, an error is created.

getVertex

public int[] getVertex(int vertexNumber,
                       int[] coords)

Fills the second argument with the coordinates of the specified vertex. The vertices are stored in a "bitwise" order. That is, vertex 0 consists of all lower coords. Vertex 1 is similar, except that it uses the upper coordinate for axis 0. In summary, the bits in the vertex number determine whether the lower or upper coordinate will be chosen for the vertex location. If the coords array is null, a new array will be created. A reference to the coords array is returned.

getVertex

public IndexSpaceID getVertex(int vertexNumber,
                              IndexSpaceID id)

Vertex 1 is similar, except that it uses the upper coordinate for axis 0. In summary, the bits in the vertex number determine whether the lower or upper coordinate will be chosen for the vertex location. If the IndexSpaceID is null, a new IntegerIndexSpaceID will be created. A reference to the coords array is returned.

public final boolean hasSameShape(ISBounds b)

Returns true if the argument bounds has the same shape as this ISBounds, and false otherwise. No explicit check of dimensionality is done, and shape checking is only done up to and including the highest dimension of this bounds. However, if the argument bounds is of a lower dimensionality than this ISBounds, a DimensionalityError will be created.

Return a new ISBounds that has upper coordinates that are exactly one greater than the upper coordinates of this ISBounds.

increaseByOne

public final void increaseByOne(ISBounds b)

Deprecated. rdb: I find the semantics very confusing. One would expect that the this object would be the one changed, not the argument object. Why do we need this? It is exactly the same as b.increaseByOne(); All other similar methods either change "this" or return a new object (except increaseByOne(ISB)).

Copies coordinates into the argument ISBounds such that the lower coordinates are unchanged, but the upper coordinates are increased by one. A convenience function.

copyScaled

public final ISBounds copyScaled(double[] scales)

Return a new ISBounds with dimensions that have been scaled by the the argument array. The lower bounds are not affected, but each coordinate of the upper bounds is modified to reflect the scaling.

copyScaled

public final ISBounds copyScaled(float[] scales)

Return a new ISBounds with dimensions that have been scaled by the the argument array. The lower bounds are not affected, but each coordinate of the upper bounds is modified to reflect the scaling.

copyScaled

public final ISBounds copyScaled(int[] scales)

Return a new ISBounds with dimensions that have been scaled by the the argument array. The lower bounds are not affected, but each coordinate of the upper bounds is modified to reflect the scaling.

move

public final ISBounds move(IndexSpaceID distance)

Translate the ISBounds object in space by the value of the parameter IndexSpaceID. Each coordinate of the IndexSpaceID is added to the coordinates of the upper and lower bounds of this ISBounds. "this" is returned for convenience of use. This is a *relative* move.

move

public final ISBounds move(int[] distance)

Translate the ISBounds object in space by the coordinates in the integer array argument. Each coordinate is added to the coordinates of the upper and lower bounds of this ISBounds. "this" is returned for convenience of use. This is a *relative* move. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created.

move

public final ISBounds move(int axis,
                           int distance)

Translate the ISBounds object in space along the specified axis by the specified distance. The distance argument is added to the coordinates of the upper and lower bounds of this ISBounds. If the specified axis is not less than the dimensionality of this ISBounds, a dimensionality error is created. "this" is returned for convenience of use. This is a *relative* move.

moveTo

public final ISBounds moveTo(IndexSpaceID location)

Translate the ISBounds object in space so that the lower left corner is moved to the location specified by the parameter IndexSpaceID. This is an *absolute* move. The IndexSpaceID should have the same dimensionality as the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created. "this" is returned for convenience of use.

moveTo

public final ISBounds moveTo(int[] location)

Translate the ISBounds object in space so that the lower left corner is moved to the coordinates specified int the integer array argument. This is an *absolute* move. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will be created. For convenience the object itself is returned as the result of the method.

moveCenterTo

public final ISBounds moveCenterTo(int[] location)

Translate the ISBounds object in space so that the center is moved to the coordinates specified in the integer array argument. This is an *absolute* move. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will be created. For convenience the object itself is returned as the result of the method.

moveCenterTo

public final ISBounds moveCenterTo(IndexSpaceID location)

Translate the ISBounds object in space so that the center is moved to the coordinates specified in the integer array argument. This is an *absolute* move. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will be created. For convenience the object itself is returned as the result of the method.

moveToOrigin

public ISBounds moveToOrigin()

Translate this ISBounds in space so that the lower point is now at the origin. For convenience, this is returned as the value of the method.

makeRelativeTo

public ISBounds makeRelativeTo(IndexSpaceID localOrigin)

Translate this ISBounds in space so it is expressed in the local coordinate system whose origin is at the IndexSpaceId passed as an argument.

makeRelativeTo

public ISBounds makeRelativeTo(int[] localOrigin)

Translate this ISBounds in space so it is expressed in the local coordinate system whose origin is at the IndexSpaceId passed as an argument.

copyAndMoveToOrigin

public static final ISBounds copyAndMoveToOrigin(ISBounds bounds)

Deprecated. Use bounds.copyToOrigin( )

Returns a new ISBounds of the same shape as the argument bounds, but moved to the origin.

boundingVolume

public final ISBounds boundingVolume(ISBounds db)

Deprecated. Use setToBoundingVolume( ISBounds )

Updates this ISBounds object to be the bounding volume of this ISBounds and the parameter ISBounds. If the dimensionality of the parameter ISBounds does not match the dimensionality of this ISBounds, then a DimensionalityException is thrown. "this" is returned for convenience of use.

setToBoundingVolume

public ISBounds setToBoundingVolume(ISBounds db)

Updates this ISBounds object to be the bounding volume of this ISBounds and the parameter ISBounds. If the dimensionality of the parameter ISBounds does not match the dimensionality of this ISBounds, then a DimensionalityException is thrown. "this" is returned for convenience of use.

intersects

public boolean intersects(ISBounds b2)

If the intersection of this with the argument is non-empty, the method returns true, and false otherwise. This object is unchanged.

intersection

public ISBounds intersection(ISBounds b2)

Returns the intersecton of this object with the ISBounds argument. If the intersection doesn't exist, then return null.

intersectWith

public ISBounds intersectWith(ISBounds b2)

Updates this ISBounds to the intersection of itself with the argument. Returns this as a convenience. Throws an exception if the intersection is null.

contains

public boolean contains(ISBounds b2)

Returns true if this Bounds completely contains the argument bounds.

containsExcludeUpper

public boolean containsExcludeUpper(int[] coords)

Returns true if this Bounds contains the coordinates represented in the integer array. Unlike the usual contains method, If the coordinates lie on an upper edge of the bounds, this method will return false. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created.

containsExcludeUpper

public boolean containsExcludeUpper(IndexSpaceID id)

Returns true if this Bounds contains the coordinates represented in the IndexSpaceID. Unlike the usual contains method, If the coordinates lie on an upper edge of the bounds, this method will return false. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created.

contains

public boolean contains(IndexSpaceID id)

Returns true if this Bounds contains the coordinates contained in the integer array. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created.

contains

public boolean contains(int[] coords)

Returns true if this Bounds contains the coordinates contained in the integer array. The array argument should have a length corresponding to the dimensionality of the bounds object. However, if the argument array is too long, the extra elements will be ignored. If it is too short, a DimensionalityError will will be created.

Return a String representing the object.

Specified by:

toString in class Bounds

toString

public java.lang.String toString(java.lang.String indent)

Return a String representing the object indented by the argument string.

main

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

For debugging. Runs basic tests on the ISBounds class.
