All Implemented Interfaces:

public abstract class AbstractDataSink
extends PropertyBundles
implements DataSink

A skeleton implementation of a data sink. acceptsData(java.lang.String) and metaData(java.util.Map) return true, setData(java.util.List) calls DataSink.clearData() and addData(java.util.List), thus only those two methods have to be implemented.

Constructor Summary

AbstractDataSink(Map<String,String> prop) Constructs a new data sink.

Method Summary

boolean	acceptsData(String any) Returns true.
boolean	addData(List<VectorG> data) For small data sets this method suffices to deviate to the DataSink.addData(Map) method.
static List<Object>	getOutliers(Map<Object,VectorG> data, DataModel fit, VectorG solution, double dev) From the user data and a data model we extract those keys that have a residual that is higher than the stated maximum discrepancy.
static Map<Object,VectorG>	mapConvert(List<VectorG> d) Converts a list of vectors to a mapping of index-to-vector.
boolean	metaData(Map<String,? extends Serializable> m) Returns true.
boolean	setData(List<VectorG> data) Sets the data by calling clear and add with the vector list.
boolean	setData(Map<Object,VectorG> d) Sets the data by calling clear and then adding the data map.
static List<VectorG>	vectorConvert(double[][] matrix) Converts a two-dimensional double array into a list of vectors.
static List<VectorG>	vectorConvert(double[] chain, int vecdim) Converts a one-dimensional double array with implicit indexing along the dimension of the vector passed over.

Constructor Detail

AbstractDataSink

protected AbstractDataSink(Map<String,String> prop)

Constructs a new data sink.

Method Detail

acceptsData

public boolean acceptsData(String any)

Returns true.

Specified by:

acceptsData in interface DataSink

Returns:

True, if this sink might use thi type of data.

metaData

public boolean metaData(Map<String,? extends Serializable> m)

Returns true.

Specified by:

metaData in interface DataSink

Returns:

False, if we cannot interprete data with the information available.

setData

public boolean setData(List<VectorG> data)

Sets the data by calling clear and add with the vector list.

Specified by:

setData in interface DataSink

Returns:

True, if we can interprete this data.

addData

public boolean addData(List<VectorG> data)

For small data sets this method suffices to deviate to the DataSink.addData(Map) method. On huge data set, you may override this to increase performance.

Specified by:

addData in interface DataSink

Returns:

True, if we can interprete this data.

setData

public boolean setData(Map<Object,VectorG> d)

Sets the data by calling clear and then adding the data map.

Specified by:

setData in interface DataSink

mapConvert

public static Map<Object,VectorG> mapConvert(List<VectorG> d)

Converts a list of vectors to a mapping of index-to-vector. We retain the order in the list

vectorConvert

public static List<VectorG> vectorConvert(double[][] matrix)

Converts a two-dimensional double array into a list of vectors. First index corresponds to the index in the list, second to the vector elements

vectorConvert

public static List<VectorG> vectorConvert(double[] chain,
                                          int vecdim)

Converts a one-dimensional double array with implicit indexing along the dimension of the vector passed over. The array is organized as v0.x v0.y v0.z [...] v1.x v1.y [...] , i.e. the vecor elements are all stitched together as on a chain.

getOutliers

public static List<Object> getOutliers(Map<Object,VectorG> data,
                                       DataModel fit,
                                       VectorG solution,
                                       double dev)

From the user data and a data model we extract those keys that have a residual that is higher than the stated maximum discrepancy. Iterating over the values in the data map must retain the order of measures in the data model
