Class ReverseDataSet

java.lang.Object

org.das2.qds.AbstractDataSet

org.das2.qds.ReverseDataSet

All Implemented Interfaces:

MutablePropertyDataSet, QDataSet

public class ReverseDataSet
extends AbstractDataSet

reverses the order of the elements of the rank 1 dataset. If there is a DEPEND_0, this is reversed as well.

ReverseDataSet

public ReverseDataSet(QDataSet source)

Method Detail

length

public int length()

Description copied from interface: QDataSet

return the length of the first dimension

Specified by:

length in interface QDataSet

Overrides:

length in class AbstractDataSet

Returns:

the length of the first dimension

value

public double value(int i)

Description copied from interface: QDataSet

rank 1 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i - the index

Returns:

the value, see the property UNITS to interpret this.

rank

public int rank()

Description copied from interface: QDataSet

returns the rank of the dataset, which is the number of indeces used to access data. Only rank 0, 1, 2, 3, and 4 datasets are supported in the interface. When a dataset's rank is 5 or greater, it should implement the HighRankDataSet interface which affords a slice operation to reduce rank.

Specified by:

rank in interface QDataSet

Specified by:

rank in class AbstractDataSet

Returns:

the rank, or number of indeces used to access data.

property

public java.lang.Object property(java.lang.String name)

Description copied from interface: QDataSet

accessor for properties attached to the dataset. See final static members for example properties.

Specified by:

property in interface QDataSet

Overrides:

property in class AbstractDataSet

Parameters:

name - property name, such as "DEPEND_0" or "UNITS"

Returns:

the value
