Method Detail

getConsolidationFunction

public CFType getConsolidationFunction()

Gets the consolidation function.

Returns:

the consolidation function

setConsolidationFunction

public void setConsolidationFunction(CFType consolidationFunction)

Sets the consolidation function.

Parameters:

consolidationFunction - the new consolidation function

setConsolidationFunction

public void setConsolidationFunction(String consolidationFunction)

Sets the consolidation function.

Parameters:

consolidationFunction - the new consolidation function

getDataSources

public List<RRADS> getDataSources()

Gets the data sources.

Returns:

the data sources

setDataSources

public void setDataSources(List<RRADS> dataSources)

Sets the data sources.

Parameters:

dataSources - the new data sources

getXff

public Double getXff()

Gets the XFF.

XFF The xfiles factor defines what part of a consolidation interval may be made up from *UNKNOWN* data while the consolidated value is still regarded as known. It is given as the ratio of allowed *UNKNOWN* PDPs to the number of PDPs in the interval. Thus, it ranges from 0 to 1 (exclusive).

Returns:

the XFF

setXff

public void setXff(Double xff)

Sets the XFF.

Parameters:

xff - the new XFF

formatEquals

public boolean formatEquals(RRA rra)

Format equals.

Parameters:

rra - the RRA object

Returns:

true, if successful
