Method Detail

getFormat

public abstract java.lang.String getFormat()

getExtension

public abstract java.lang.String getExtension()

tearDown

public void tearDown()

Does nothing.

Specified by:

tearDown in class ResultSetExampleSource

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.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class ResultSetExampleSource
