org.apache.poi.hssf.record.aggregates.RecordAggregate

org.apache.poi.hssf.record.aggregates.FormulaRecordAggregate

All Implemented Interfaces:

CellValueRecordInterface

public final class FormulaRecordAggregate
extends RecordAggregate
implements CellValueRecordInterface

The formula record aggregate is used to join together the formula record and it's (optional) string record and (optional) Shared Formula Record (template reads, excel optimization).

Constructor Detail

FormulaRecordAggregate

public FormulaRecordAggregate(FormulaRecord formulaRec,
                              StringRecord stringRec,
                              SharedValueManager svm)

Parameters:

stringRec - may be null if this formula does not have a cached text value.

svm - the SharedValueManager for the current sheet

Method Detail

getFormulaRecord

public FormulaRecord getFormulaRecord()

getStringRecord

public StringRecord getStringRecord()

debug only TODO - encapsulate

getXFIndex

public short getXFIndex()

Specified by:

getXFIndex in interface CellValueRecordInterface

setXFIndex

public void setXFIndex(short xf)

Specified by:

setXFIndex in interface CellValueRecordInterface

setColumn

public void setColumn(short col)

Specified by:

setColumn in interface CellValueRecordInterface

Parameters:

col - the column this cell defines

setRow

public void setRow(int row)

Specified by:

setRow in interface CellValueRecordInterface

Parameters:

row - the row this cell occurs within

getColumn

public short getColumn()

Specified by:

getColumn in interface CellValueRecordInterface

Returns:

the column this cell defines within the row

getRow

public int getRow()

Specified by:

getRow in interface CellValueRecordInterface

Returns:

the row this cell occurs on

toString

public String toString()

Overrides:

toString in class 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 Records being used to manage POI's internal implementation. Callers should not assume either way, and therefore only attempt to modify those Records after cloning

Specified by:

visitContainedRecords in class RecordAggregate

Parameters:

rv - The visitor to use for callbacks while walking this object

getStringValue

public String getStringValue()

setCachedStringResult

public void setCachedStringResult(String value)

setCachedBooleanResult

public void setCachedBooleanResult(boolean value)

setCachedErrorResult

public void setCachedErrorResult(int errorCode)

setCachedErrorResult

public void setCachedErrorResult(FormulaError error)

setCachedDoubleResult

public void setCachedDoubleResult(double value)

getFormulaTokens

public Ptg[] getFormulaTokens()

setParsedExpression

public void setParsedExpression(Ptg[] ptgs)

Also checks for a related shared formula and unlinks it if found

unlinkSharedFormula

public void unlinkSharedFormula()

notifyFormulaChanging

public void notifyFormulaChanging()

Should be called by any code which is either deleting this formula cell, or changing its type. This method gives the aggregate a chance to unlink any shared formula that may be involved with this cell formula.

isPartOfArrayFormula

public boolean isPartOfArrayFormula()

getArrayFormulaRange

public CellRangeAddress getArrayFormulaRange()

setArrayFormula

public void setArrayFormula(CellRangeAddress r,
                            Ptg[] ptgs)

removeArrayFormula

public CellRangeAddress removeArrayFormula(int rowIndex,
                                           int columnIndex)

Removes an array formula

Returns:

the range of the array formula containing the specified cell. Never null
