## org.apache.poi.hssf.record.aggregates
Class CFRecordsAggregate

    java.lang.Object
      org.apache.poi.hssf.record.RecordBase
          org.apache.poi.hssf.record.aggregates.RecordAggregate
              org.apache.poi.hssf.record.aggregates.CFRecordsAggregate

    public final class CFRecordsAggregate

extends RecordAggregate

CFRecordsAggregate - aggregates Conditional Formatting records CFHeaderRecord and number of up CFRuleRecord records together to simplify access to them.

Note that Excel versions before 2007 can only cope with a maximum of 3 Conditional Formatting rules per sheet. Excel 2007 or newer can cope with unlimited numbers, as can Apache OpenOffice. This is an Excel limitation, not a file format one.

Constructor Detail

### CFRecordsAggregate

    public CFRecordsAggregate(CellRangeAddress[] regions,
                              CFRuleBase[] rules)

Method Detail

### createCFAggregate

    public static CFRecordsAggregate createCFAggregate(RecordStream rs)

  Create CFRecordsAggregate from a list of CF Records

  Parameters:
    `rs` - - the stream to read from
  Returns:
    CFRecordsAggregate object

### cloneCFAggregate

    public CFRecordsAggregate cloneCFAggregate()

  Create a deep clone of the record

### getHeader

    public CFHeaderBase getHeader()

  Returns:
    the header. Never `null`.

### getRule

    public CFRuleBase getRule(int idx)

### setRule

    public void setRule(int idx,
                        CFRuleBase r)

### addRule

    public void addRule(CFRuleBase r)

### getNumberOfRules

    public int getNumberOfRules()

### toString

    public java.lang.String toString()

  String representation of CFRecordsAggregate

  Overrides:
    `toString` in class `java.lang.Object`

### visitContainedRecords

    public void visitContainedRecords(RecordAggregate.RecordVisitor rv)

  Description copied from class: `RecordAggregate`
  Visit each of the atomic BIFF records contained in this `RecordAggregate` in the order that they should be written to file. Implementors may or may not return the actual `Record`s being used to manage POI's internal implementation. Callers should not assume either way, and therefore only attempt to modify those `Record`s after cloning

  Specified by:
    `visitContainedRecords` in class `RecordAggregate`

### updateFormulasAfterCellShift

    public boolean updateFormulasAfterCellShift(FormulaShifter shifter,
                                                int currentExternSheetIx)

  Returns:
    `false` if this whole `CFHeaderRecord` / `CFRuleRecord`s should be deleted
