                                   Units u)

create

public static DRank0DataSet create(Datum d)

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.

value

public double value()

Description copied from interface: QDataSet

rank 0 accessor.

Specified by:

value in interface QDataSet

Specified by:

value in interface RankZeroDataSet

Overrides:

value in class AbstractDataSet

Returns:

the value, see the property UNITS to interpret this.

toString

public java.lang.String toString()

Description copied from class: AbstractDataSet

return a human-readable string representation of this QDataSet.

Overrides:

toString in class AbstractDataSet

Returns:

a human-readable string representation of this QDataSet.

See Also:

DataSetUtil.toString(org.das2.qds.QDataSet)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

implement the equals method to at least return true for two DRank0DataSets. This was motivated by cadence parameter being dropped because they were not equal.

Overrides:

equals in class java.lang.Object

Parameters:

obj -

Returns:
