## org.das2.qds.util.DataSetBuilder

allows dataset of unknown length to be built. Presently, this only builds QUBES, but should allow for geometry changes. TODO: consider using WritableDataSet interface. The guessRecCount parameter is the initial number of allocated records, and is also the extension when this number of records is passed. The final physical dataset size is not affected by this, because the data is copied.

## DataSetBuilder( int rank )

Create a new builder for a rank 0 dataset.

## DataSetBuilder( int rank, int guessRecCount )

Create a new builder for a rank 1 dataset. guessRecCount is the guess of dim0 size. Bad guesses will simply result in an extra array copy.

## DataSetBuilder( int rank, int guessRecCount, int dim1 )

Create a new builder for a rank 2 dataset. guessRecCount is the guess of dim0 size. Bad guesses will simply result in an extra array copy.

## DataSetBuilder( int rank, int guessRecCount, int dim1, int dim2 )

Create a new builder for a rank 3 dataset. guessRecCount is the guess of dim0 size. Bad guesses will simply result in an extra array copy.

## DataSetBuilder( int rank, int guessRecCount, int dim1, int dim2, int dim3 )

Create a new builder for a rank 4 dataset. guessRecCount is the guess of dim0 size. Bad guesses will simply result in an extra array copy.

## nextRecord

nextRecord( ) → void

This must be called each time a record is complete. Note this currently advances to the next record and at this point the next record exists. In other words, the last call to nextRecord is not required. This logic may change, so that any fields written would be dropped unless nextRecord is called to commit the record. When -1 is used for the indexes of the streaming dimension, then this will increment the internal counter. TODO: Check for unspecified entries.

### Returns:

void (returns nothing)

### See Also:

nextRecord(java.lang.Object...) which inserts all values at once.
[search for examples] [view on GitHub] [view on old javadoc] [view source]

## nextRecord

nextRecord( double[] values ) → void

In one step, specify all the values of the record and advance the counter. This is intended to reduce the number of lines needed in scripts, and to support Jython where a double array would not be cast to an Object array. Also, columns 1..N-1 are declared dependent on column 0, when column 0 is UT times.

### Parameters

values - the record values.

### Returns:

void (returns nothing)

### See Also:

nextRecord(java.lang.Object...)

## nextRecord

nextRecord( Object[] values ) → void

In one step, specify all the values of the record and advance the counter. This is intended to reduce the number of lines needed in scripts. In Jython:

>     dsb= DataSetBuilder(2,100,2)
>     dsb.nextRecord( [ '2014-001T00:00', 20. ] )
>     dsb.nextRecord( [ '2014-002T00:00', 21. ] )
>     dsb.nextRecord( [ '2014-003T00:00', 21.4 ] )
>     dsb.nextRecord( [ '2014-004T00:00', 19.7 ] )
>     ds= dsb.getDataSet()

Also, columns 1..N-1 are declared dependent on column 0, when column 0 is UT times.

### Parameters

values - the record values, in an String, Datum, Rank 0 QDataSet, or Number.

### Returns:

void (returns nothing)

## nextRecords

nextRecords( QDataSet ds ) → void

add each of the records of ds to the builder. This is somewhat equivalent to:

     for d in ds: dsb.nextRecord(d)

(Note the above only works when ds is rank 1.) Though this is equivalent, this is provided because a future implementation may peek at the dataset to transfer data more efficiently.

### Parameters

ds - dataset with rank N, where N is the rank of this builder.

### Returns:

void (returns nothing)
