Constructor Detail

CdsMocBuilder

protected CdsMocBuilder(cds.moc.Moc1D moc)

Constructor.

Parameters:

moc - CDS Moc1d instance

Method Detail

createOrderedUniqIterator

public PrimitiveIterator.OfLong createOrderedUniqIterator()

Description copied from interface: MocBuilder

Returns an iterator over the UNIQ values represented by this MOC in sequence. That means that the lower-order ones come first.

Should only be called after MocBuilder.endTiles() has been called.

Specified by:

createOrderedUniqIterator in interface MocBuilder

getOrderCounts

public long[] getOrderCounts()

Description copied from interface: MocBuilder

Returns an array of the number of tiles present at each order of the normalised MOC. The length of the array gives the number of orders present (the last element may not be zero, unless only one element is returned). The sum of the elements of this array gives the number of values that will be returned by MocBuilder.createOrderedUniqIterator().

Should only be called after MocBuilder.endTiles() has been called.

Specified by:

getOrderCounts in interface MocBuilder

createCdsSMocBuilder

public static MocBuilder createCdsSMocBuilder(int maxOrder,
                                              int batchSize)

Returns a Spatial MOC instance of this class that may or may not use tile batching to affect performance.

Parameters:

maxOrder - maximum HEALPix order of the SMOC

batchSize - if >1, pixels are added in batches per order, which may result in improved performance

createCdsMocBuilder

public static MocBuilder createCdsMocBuilder(cds.moc.Moc1D moc,
                                             int batchSize)

Returns an instance of this class that may or may not use tile batching to affect performance.

Parameters:

moc - CDS Moc1D instance

batchSize - if >1, pixels are added in batches per order, which may result in improved performance
