Constructor Detail

IndexGenDataSet

public IndexGenDataSet(int length)

Creates a new instance of IndexGenDataSet

Parameters:

length -

Method Detail

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(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.

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

lastindex

public static QDataSet lastindex(QDataSet src)

this is used to create a 0,1,2,... index list when DEPEND_1 is rank 2, but this also works for rank 1.

Parameters:

src -

Returns:
