Constructor Detail

ManhattanDataObject

public ManhattanDataObject(Instance originalInstance,
                           java.lang.String key,
                           Database database)

Constructs a new DataObject. The original instance is kept as instance-variable

Parameters:

originalInstance - the original instance

Method Detail

equals

public boolean equals(DataObject dataObject)

Compares two DataObjects in respect to their attribute-values

Specified by:

equals in interface DataObject

Parameters:

dataObject - The DataObject, that is compared with this.dataObject; now assumed to be of the same type and with the same structure

Returns:

Returns true, if the DataObjects correspond in each value, else returns false

distance

public double distance(DataObject dataObject)

Calculates the manhattan-distance between dataObject and this.dataObject

Specified by:

distance in interface DataObject

Parameters:

dataObject - The DataObject, that is used for distance-calculation with this.dataObject now assumed to be of the same type and with the same structure

Returns:

double-value The manhattan-distance between dataObject and this.dataObject NaN, if the computation could not be performed

getInstance

public Instance getInstance()

Returns the original instance

Specified by:

getInstance in interface DataObject

Returns:

originalInstance

getKey

Returns the key for this DataObject

Specified by:

getKey in interface DataObject

Returns:

key

setKey

public void setKey(java.lang.String key)

Sets the key for this DataObject

Specified by:

setKey in interface DataObject

Parameters:

key - The key is represented as string

setClusterLabel

public void setClusterLabel(int clusterID)

Sets the clusterID (cluster), to which this DataObject belongs to

Specified by:

setClusterLabel in interface DataObject

Parameters:

clusterID - Number of the Cluster

getClusterLabel

public int getClusterLabel()

Returns the clusterID, to which this DataObject belongs to

Specified by:

getClusterLabel in interface DataObject

Returns:

clusterID

setProcessed

public void setProcessed(boolean processed)

Marks this dataObject as processed

Specified by:

setProcessed in interface DataObject

Parameters:

processed - True, if the DataObject has been already processed, false else

isProcessed
