Constructor Summary
`Repeat()`

Method Summary
`java.lang.String` | `generateConditionForOp(int columnSetIndex)` Not needed because method `generateSQLDefinition` is overridden.
`java.lang.String` | `generateSQLDefinition(java.lang.String selectPart, int index)` Overrides the method from Segmentation.java because no where-clause is needed.
`int` | `numberOfSegments()` Getter method for parameter "HowOften".
`void` | `setCSSegmentInfo(java.lang.String inputMultiStepBranch, Columnset cs, int index)` Abstract method to be implemented by all Segmentation operators.

Constructor Detail

### Repeat

    public Repeat()

Method Detail

### generateConditionForOp

    public java.lang.String generateConditionForOp(int columnSetIndex)
                                            throws M4CompilerError

  Not needed because method `generateSQLDefinition` is overridden.

  Specified by:
    `generateConditionForOp` in class `Segmentation`
  Parameters:
    `columnSetIndex` - The number of the columnset for which the condition is to be generated
  Returns:
    the SQL condition as a String
  Throws:
    `M4CompilerError`
  See Also:
    `Segmentation.generateConditionForOp(int)`

### generateSQLDefinition

    public java.lang.String generateSQLDefinition(java.lang.String selectPart,
                                                  int index)
                                           throws M4CompilerError

  Overrides the method from Segmentation.java because no where-clause is needed.

  Overrides:
    `generateSQLDefinition` in class `Segmentation`
  Throws:
    `M4CompilerError`
  See Also:
    `edu.udo.cs.miningmart.m4.core.operator.ConceptOperator#generateSQLDefinition(String, int)`

### numberOfSegments

    public int numberOfSegments()
                         throws M4CompilerError

  Getter method for parameter "HowOften".

  Specified by:
    `numberOfSegments` in class `Segmentation`
  Returns:
    the parameter "HowOften" as an integer
  Throws:
    `M4CompilerError`
  See Also:
    `edu.udo.cs.miningmart.m4.core.operator.Segmentation#numberOfSegments`

### setCSSegmentInfo

    public void setCSSegmentInfo(java.lang.String inputMultiStepBranch,
                                 Columnset cs,
                                 int index)
                          throws M4CompilerError

  Description copied from class: `Segmentation`
  Abstract method to be implemented by all Segmentation operators. The multistep information about how the segmentation was done is set into the newly created columnset.

  Specified by:
    `setCSSegmentInfo` in class `Segmentation`
  Parameters:
    `inputMultiStepBranch` - the multistep information of the input columnset
    `cs` - the current output columnset
    `index` - the index of the output columnset
  Throws:
    `M4CompilerError`
  See Also:
    `edu.udo.cs.miningmart.m4.core.operator.Segmentation#setCSSegmentInfo(String, Columnset, int)`
