Class DArrayDimension

java.lang.Object

opendap.dap.DAPNode

opendap.dap.DArrayDimension

All Implemented Interfaces:

Serializable, Cloneable

public final class DArrayDimension
extends DAPNode

This class holds information about each dimension in a DArray. Each array dimension carries with it its own projection information, as well as it's name and size.

The projection information takes the form of three integers: the start, stop, and stride values. This is clearest with an example. Consider a one-dimensional array 10 elements long. If the start value of the dimension constraint is 3, then the constrained array appears to be seven elements long. If the stop value is changed to 7, then the array appears to be five elements long. If the stride is changed to two, the array will appear to be 3 elements long. Array constraints are written as [start:stride:stop].

Constructor Detail

DArrayDimension

public DArrayDimension(int size,
                       String name)

Construct a new DArrayDimension.

Parameters:

size - The size of the dimension.

name - The dimension's name, or null if no name.

Method Detail

getSize

public int getSize()

Get the dimension size.

setSize

public void setSize(int size)

Set the dimension size.

getStart

public int getStart()

Get the projection start point for this dimension.

getStride

public int getStride()

Get the projection stride size for this dimension.

getStop

public int getStop()

Get the projection stop point for this dimension.

setContainer

public void setContainer(DArray da)

getContainer

public DArray getContainer()

printConstraint

public void printConstraint(PrintWriter os)

setProjection

public void setProjection(int start,
                          int stride,
                          int stop)
                   throws InvalidDimensionException

Set the projection information for this dimension. The parameters start stride and stop are checked to verify that they make sense relative to each other and to the size of this dimension. If not an Invalid ParameterException is thrown. The general rule is: 0<=start<size, 0<stride, 0<=stop<size, start<=stop.

Parameters:

start - The starting point for the projection of this DArrayDimension.

stride - The size of the stride for the projection of this DArrayDimension.

stop - The stopping point for the projection of this DArrayDimension.

Throws:

InvalidDimensionException

cloneDAG

public DAPNode cloneDAG(DAPNode.CloneMap map)
                 throws CloneNotSupportedException

Returns a clone of this Array. See DAPNode.cloneDag()

Overrides:

cloneDAG in class DAPNode

Parameters:

map - track previously cloned nodes

Returns:

a clone of this object.

Throws:

CloneNotSupportedException
