Method Summary

abstract java.lang.String	getExtension()
abstract java.lang.String	getFormat()
java.util.List<ParameterType>	getParameterTypes() Returns a list of ParameterTypes describing the parameters of this operator.
java.sql.ResultSet	getResultSet() Returns a ResultSet.
void	setNominalValues(java.util.List attributeList, java.sql.ResultSet resultSet, Attribute label) Since the ResultSet does not provide information about possible values of nominal attributes, subclasses must set these by implementing this method.

Method Detail

getFormat

public abstract java.lang.String getFormat()

getExtension

public abstract java.lang.String getExtension()

getResultSet

public java.sql.ResultSet getResultSet()
                                throws UndefinedParameterError

Description copied from class: ResultSetExampleSource

Returns a ResultSet.

Specified by:

getResultSet in class ResultSetExampleSource

Throws:

UndefinedParameterError

setNominalValues

public void setNominalValues(java.util.List attributeList,
                             java.sql.ResultSet resultSet,
                             Attribute label)
                      throws OperatorException

Description copied from class: ResultSetExampleSource

Since the ResultSet does not provide information about possible values of nominal attributes, subclasses must set these by implementing this method.

Specified by:

setNominalValues in class ResultSetExampleSource

Parameters:

attributeList - List of Attribute

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Overrides:
