Constructor Detail

### TimeOperator

    public TimeOperator()

Method Detail

### getColumnSetSuffix

    protected abstract java.lang.String getColumnSetSuffix()

  Returns:
    the suffix added to the concept name to get the name of the new column set

### runStoredProcedure

    protected abstract void runStoredProcedure(java.lang.String newColumnSetName)
                                        throws java.sql.SQLException,
                                               M4CompilerError,
                                               TimeOperatorException

  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.

  Parameters:
    `newColumnSetName` - the name of the table to be created for the results
  Throws:
    `java.sql.SQLException`
    `M4CompilerError`
    `TimeOperatorException`

### createJavaColumns

    protected abstract void createJavaColumns(Columnset newColumnSet)
                                       throws java.sql.SQLException,
                                              M4CompilerError

  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.

  Parameters:
    `newColumnSet` - the new column set generated by this operator
  Throws:
    `java.sql.SQLException`
    `M4CompilerError`

### generateSQLDefinition

    public java.lang.String generateSQLDefinition(java.lang.String selectPart)
                                           throws M4CompilerError

  Description copied from class: `SingleCSOperator`
  This method must return the SQL definition of the newly created ColumnSet.

  Specified by:
    `generateSQLDefinition` in class `SingleCSOperator`
  Parameters:
    `selectPart` - The SQL string between "SELECT" and "FROM" for the SQL definition to be returned.
  Returns:
    The SQL definition for the new ColumnSet.
  Throws:
    `M4CompilerError`

### getTypeOfNewColumnSet

    public java.lang.String getTypeOfNewColumnSet()

  Description copied from class: `SingleCSOperator`
  This method must return the entry String for the M4 table "Columnset_t", indicating whether the new Columnset is a view or a table.

  Specified by:
    `getTypeOfNewColumnSet` in class `SingleCSOperator`
  Returns:
    the type of `Columnset`, a table in this case.
  See Also:
    `edu.udo.cs.miningmart.m4.core.operator.ConceptOperator#getTypeOfNewColumnSet`

### mustCopyFeature

    protected boolean mustCopyFeature(java.lang.String nameOfFeature)

  Description copied from class: `ConceptOperator`
  This method is for operators that do not copy all Features of the input concept to the output concept.

  Specified by:
    `mustCopyFeature` in class `ConceptOperator`
  Parameters:
    `nameOfFeature` - Name of the feature in question.
  Returns:
    TRUE if this feature should be copied to the output concept, FALSE if not.

### createSingleColumnSet

    protected Columnset createSingleColumnSet(int index)
                                       throws M4CompilerError

  This method overrides the method in ConceptOperator! This method holds the control structure of the class TimeOperator. It generates the name of the new column set to be created, calls the method for running the stored procedure and registers the new column set linked to the output concept in the JAVA cache for M4 objects.

  Overrides:
    `createSingleColumnSet` in class `ConceptOperator`
  Parameters:
    `index` - Can be ignored as this is a SingleCSOperator.
  Returns:
    The new Columnset for the output concept.
  Throws:
    `M4CompilerError`

### createM4Column

    protected Column createM4Column(BaseAttribute outputBA,
                                    Columnset newCS,
                                    Column columnForType)
                             throws M4CompilerError

  Throws:
    `M4CompilerError`

### executeDbProcedure

    protected void executeDbProcedure(java.lang.String procedureName,
                                      java.lang.String[] parameters)
                               throws M4CompilerError

  Throws:
    `M4CompilerError`

### getQuotedColNameforInpBA

    protected static java.lang.String getQuotedColNameforInpBA(BaseAttribute ba)
                                                        throws M4CompilerError

  Throws:
    `M4CompilerError`

### getQuotedColNameforOutBA

    protected static java.lang.String getQuotedColNameforOutBA(BaseAttribute ba)

### getQuotedColSetNameforCon

    protected static java.lang.String getQuotedColSetNameforCon(Concept c)
                                                         throws M4CompilerError

  Throws:
    `M4CompilerError`

### getUnquotedIntFromValue

    protected static java.lang.String unquote(java.lang.String s)

### valueIsLong

                               java.lang.String name)
                        throws M4CompilerError

  Throws:
    `M4CompilerError`

### valueIsDouble

    protected void valueIsDouble(Value v,
                                 java.lang.String name)
                          throws M4CompilerError

  Throws:
    `M4CompilerError`

### baseattribHasColumns

    protected void baseattribHasColumns(BaseAttribute b,
                                        java.lang.String name)
                                 throws M4CompilerError
