Class DataQueryModel

java.lang.Object

org.licas.data.DataQueryModel

Direct Known Subclasses:

ComparisonQueryModel

public class DataQueryModel
extends java.lang.Object

Query object for defining what an evaluator should evaluate. This version stores a method description and an object to evaluate. Typically, the parent service is invoked with the method details using Reflection and the data object as the target.

Constructor Detail

DataQueryModel

public DataQueryModel()

Create a new instance of DataQueryModel

Method Detail

distanceFunction

public org.ai_heuristic.functs.Function distanceFunction()
                                                  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 distance query, the function should implement the FunctionMetricDef interface, so that its method list is known.

Parameters:

functionClassname - the evaluator class name.

getFunctionClass

public java.lang.String getFunctionClass()

Get the class name of the math evaluator.

Returns:

the value of mathCompare.

setDataType

public void setDataType(java.lang.String thisDataType)

Set the data type.

Parameters:

thisDataType - the data type.

getDataType

public java.lang.String getDataType()

Get the data type for the data object to be evaluated.

Returns:

the value of dataType.

setDataset

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

Set the dataset object.

Parameters:

thisDataSet - the dataset object.

getDataset

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

Get the dataset object.

Returns:

the value of dataSet.

setParams

public void setParams(java.util.LinkedHashMap<java.lang.String,java.lang.Object> theParams)

Set the additional parameters list.

Parameters:

theParams - the additional parameters as key-value pairs.

getParams

public java.util.LinkedHashMap<java.lang.String,java.lang.Object> getParams()

Get the additional parameters list.

Returns:

the value of params.

isDataQuery

public static boolean isDataQuery(java.lang.Object dataObj)

Return true if the data object is an instance of a known data query type.

Parameters:

dataObj - the data object.

Returns:

true if a DataQueryModel or a ComparisonQueryModel.

clone

public java.lang.Object clone()

Return a deep clone this object.

Overrides:

clone in class java.lang.Object

Returns:

a copy of this object.
