Class DataSetBuilder

java.lang.Object
  org.virbo.dsutil.DataSetBuilder

public class DataSetBuilder
extends java.lang.Object

allows dataset of unknown length to be built. Presently, this only builds QUBES, but should allow for geometry changes. TODO: consider using WritableDataSet interface.

Constructor Detail

DataSetBuilder

public DataSetBuilder(int rank,
                      int recCount)

recCount is the guess of dim0 size. Bad guesses will result in an extra copy.

Parameters:

recCount - initial allocation for the first dimension.

DataSetBuilder

public DataSetBuilder(int rank,
                      int recCount,
                      int dim1)

recCount is the guess of dim0 size. Bad guesses will result in an extra copy.

Parameters:

recCount - initial allocation for the first dimension.

dim1 - when rank 2 or greater is used.

public DataSetBuilder(int rank,
                      int recCount,
                      int dim1,
                      int dim2)

recCount is the guess of dim0 size. Bad guesses may result in an extra copy.

Parameters:

recCount - initial allocation for the first dimension.

dim1 - when rank 2 or greater is used.

dim2 - when rank 3 or greater is used.

Method Detail

putValue

public void putValue(int index0,
                     double d)

index0 is ignored!!!

putValue

public void putValue(int index0,
                     int index1,
                     double d)

index0 is ignored!!!

putValue

public void putValue(int index0,
                     int index1,
                     int index2,
                     double d)

index0 is ignored!!!

putValues

public void putValues(int index0,
                      DDataSet values,
                      int count)

copy the elements from one DDataSet into the builder (which can be done with a system call), ignoring dataset geometry. TODO: since the element count allows for putting multiple records in at once, an index out of bounds may occur after the last record of current is written.

Parameters:

index0 -

values -

count - the number of elements to copy

nextRecord

public void nextRecord()

This must be called each time a record is complete. TODO: I always forget to call this, find another way to do this. Check for unspecified entries.

getRecordElements

public int getRecordElements()

return the number of elements in each record.

Returns:

getDataSet

public DDataSet getDataSet()

returns the result dataset, concatenating all the datasets it's built thus far.

putProperty

get a map of all the properties set thus far.

Returns:

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener l)

Adds a PropertyChangeListener to the listener list.

Parameters:

l - The listener to add.

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener l)
