void	close() Closes the connection and other JDBC related objects.
MiningRule	getNextRule() Returns the next mining rule in the rule set.
MiningRule[]	getNextRules(int numRules) Returns the specified number of mining rules from the rule set.
int	getNumberOfRules() Returns the number of rules in the rule set.

Method Detail

getNumberOfRules

public int getNumberOfRules()

Returns the number of rules in the rule set.

Returns:

int - The number of rules

getNextRule

public MiningRule getNextRule()
                                           throws java.sql.SQLException,
MiningObjectException,
ODMException

Returns the next mining rule in the rule set.

Returns:

MiningRule - The retrieved mining rule

Throws:

java.sql.SQLException - when an error occurs during execution of rules retrieval.

MiningObjectException - when a retrieved rule is invalid.

ODMException - when an unknown error occurs during rules retrieval.

getRules

public MiningRule[] getRules()
                                          throws java.sql.SQLException,
MiningObjectException,
ODMException

Returns all mining rules in the rule set. In case of AssociationRules model, this method returns only the all the next rules from the current rule position.

Returns:

MiningRule[] - An array of mining rules

Throws:

java.sql.SQLException - when an error occurs during execution of rules retrieval.

MiningObjectException

ODMException

close

public void close()
           throws java.sql.SQLException

Closes the connection and other JDBC related objects. This method must be invoked when the rules in the rule set are retrieved.

Throws:

java.sql.SQLException - when an error occurs while closing the connection and JDBC related objects.

getNextRules

public MiningRule[] getNextRules(int numRules)
                                              throws java.sql.SQLException,
InvalidArgumentException,
MiningObjectException,
ODMException

Returns the specified number of mining rules from the rule set.

Parameters:

numRules - The number of rules to be retrieved

Returns:

MiningRule[] - An array of retrieved mining rules

Throws:

java.sql.SQLException - when an error occurs during execution of rules retrieval.

MiningObjectException - when a retrieved rule is invalid.

ODMException - when an unknown error occurs during rules retrieval.

InvalidArgumentException
