org.das2.dataset.TableDataSet

A DataSet implementation for 3 dimensional z(x,y) data sets where the data is arranged in a sequence of tables. Each table will have a set of monotonically increasing x tags and y tags. The x tags for all the tables, when taken together in the order that the table are in, will be monotonically increasing over the whole data set. The y tags are constant over the y scans of each table, but may change, either in number or value, from table to table.

getDatum

getDatum( int i, int j ) → Datum

Returns the Z value for the given indices into the x and y tags as a Datum.

Parameters

i - index of the x tag for the requested value.
j - index of the y tag for the requested value.

Returns:

the value at index location (i, j) as a Datum

getDouble

getDouble( int i, int j, Units units ) → double

Returns the Z value for the given indices into the x and y tags as a double with the given units.

Parameters

i - index of the y tag for the requested value.
j - index of the x tag for the requested value.
units - the units the returned value should be converted to.

Returns:

the value at index location (i, j) as a double.
