equals

boolean equals(DataObject dataObject)

Compares two DataObjects in respect to their attribute-values

Parameters:

dataObject - The DataObject, that is compared with this.dataObject

Returns:

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

distance

double distance(DataObject dataObject)

Calculates the distance between dataObject and this.dataObject

Parameters:

dataObject - The DataObject, that is used for distance-calculation with this.dataObject

Returns:

double-value The distance between dataObject and this.dataObject

getInstance

Instance getInstance()

Returns the original instance

Returns:

originalInstance

getKey

String getKey()

Returns the key for this DataObject

Returns:

key

setKey

Returns:

clusterID

setProcessed

void setProcessed(boolean processed)

Marks this dataObject as processed

Parameters:

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

isProcessed

boolean isProcessed()

Gives information about the status of a dataObject
