Interface ComputeStatisticsTask

All Superinterfaces:

MiningObject, Task

public interface ComputeStatisticsTask

extends Task

ComputeStatisticsTask is a task that computes statistics on the specified data.

If no LogicalData is specified, the task computes statistics as if the LogicalData were created directly from the PhysicalData.

If LogicalData is specified, it indicates which attributes have statistics computed and provides directives as to how data should be interpreted.

It is implementation defined as to which statistics are computed for each attribute type.

Method Summary

java.lang.String	getLogicalDataName() Returns the name of the LogicalData object.
java.lang.String	getPhysicalDataName() Returns the name of the PhysicalDataSet from which statistics are to be computed.
void	setLogicalDataName(java.lang.String logicalDataName) Sets the name of the LogicalData to be used as a reference for more detailed attribute information that can direct statistics computation.
void	setPhysicalDataName(java.lang.String name) Sets the name of the PhysicalDataSet from which statistics are computed.
VerificationReport	verify() Determines whether the specification of the compute statistics task is correct.

setLogicalDataName

public void setLogicalDataName(java.lang.String logicalDataName)
                        throws JDMException

Sets the name of the LogicalData to be used as a reference for more detailed attribute information that can direct statistics computation.

Parameters:

logicalDataName -

Returns:

void

Throws:

JDMException

setPhysicalDataName

public void setPhysicalDataName(java.lang.String name)
                         throws JDMException

verify

public VerificationReport verify()

Determines whether the specification of the compute statistics task is correct. This includes a check if the physical data name is valid, and the logical data name is valid, if present.

Returns:

VerificationReport
