Class ComparisonQueryModel

java.lang.Object

org.licas.data.DataQueryModel

org.licas.data.ComparisonQueryModel

public class ComparisonQueryModel
extends DataQueryModel

Query object for defining what an evaluator should evaluate. This version creates a math comparison operator from its class name and invokes the method on that operator. It therefore requires the two datasets that are being compared and the comparison operator. It should also implement the EvaluateMathDef interface.

Method Detail

compareFunction

public org.ai_heuristic.def.EvaluateMathDef compareFunction()
                                                     throws java.lang.Exception

Create the math comparison object from the stored class name.

Returns:

the math comparison object, created using LoadObject, with an empty constructor.

Throws:

java.lang.Exception - any error.

setFunctionClass

public void setFunctionClass(java.lang.String functionClassname)

Set the class name of the evaluator. For a comparison query, the function should implement the EvaluateMathDef interface, so that its method list is known.

Overrides:

setFunctionClass in class DataQueryModel

Parameters:

functionClassname - the evaluator class name.

setOperator

public void setOperator(java.lang.String thisOperator)

Set the comparison operator. Null for evaluation on single object.

Parameters:

thisOperator - the comparison operator.

getOperator

public java.lang.String getOperator()

Get the comparison operator. Null for single evaluation.

Returns:

the value of operator.

setCompareWith

public void setCompareWith(org.ai_heuristic.eval.metric.MetricDataset thisDataSet)

Set the dataset object to compare with. Null for a single evaluation.

Parameters:

thisDataSet - the dataset object.

getCompareWith

public org.ai_heuristic.eval.metric.MetricDataset getCompareWith()

Get the dataset object to compare with.

Returns:

the value of compareWith.
