Constructor Detail

ExponentialMovingFunction

public ExponentialMovingFunction()
Method Detail

getColumnSetSuffix

protected java.lang.String getColumnSetSuffix()
Specified by:
getColumnSetSuffix in class TimeOperator
Returns:
the suffix added to the concept name to get the name of the new column set

getTimeBaIn

public BaseAttribute getTimeBaIn()
                          throws M4CompilerError
Throws:
M4CompilerError

getValueBaIn

public BaseAttribute getValueBaIn()
                           throws M4CompilerError
Throws:
M4CompilerError

getTimeBaOut

public BaseAttribute getTimeBaOut()
                           throws M4CompilerError
Throws:
M4CompilerError

getValueBaOut

public BaseAttribute getValueBaOut()
                            throws M4CompilerError
Throws:
M4CompilerError

getHeadWeight

public Value getHeadWeight()
                    throws M4CompilerError
Throws:
M4CompilerError

getTailWeight

public Value getTailWeight()
                    throws M4CompilerError
Throws:
M4CompilerError

getDistance

public Value getDistance()
                  throws M4CompilerError
Throws:
M4CompilerError

createJavaColumns

protected void createJavaColumns(Columnset newCS)
                          throws java.sql.SQLException,
                                 M4CompilerError
Description copied from class: TimeOperator
This method needs to create the M4 JAVA objects for the new columns and has to link these objects to the base attributes (and vice versa). Additionally the new columns need to be linked to the column set (and vice versa). If an operator creates base attributes by a kind of template mechanism, then the links of these objects to the concept should be set here, as well.

Specified by:
createJavaColumns in class TimeOperator
Parameters:
newCS - the new column set generated by this operator
Throws:
java.sql.SQLException
M4CompilerError

runStoredProcedure

protected void runStoredProcedure(java.lang.String newColumnsetName)
                           throws java.sql.SQLException,
                                  M4CompilerError,
                                  TimeOperatorException
Description copied from class: TimeOperator
This method calls the stored procedure in the database. It passes all the involved table and column names to the stored procedure, which creates a new table for the results.

Specified by:
runStoredProcedure in class TimeOperator
Parameters:
newColumnsetName - the name of the table to be created for the results
Throws:
java.sql.SQLException
M4CompilerError
TimeOperatorException
