create
public static SharedValueManager create(SharedFormulaRecord[] sharedFormulaRecords,
ArrayRecord[] arrayRecords,
TableRecord[] tableRecords)
- Parameters:
recs
- list of sheet records (possibly contains records for other parts of the Excel file)startIx
- index of first row/cell record for current sheetendIx
- one past index of last row/cell record for current sheet. It is important
that this code does not inadvertently collect SharedFormulaRecords from any other
sheet (which could happen if endIx is chosen poorly). (see bug 44449)
linkSharedFormulaRecord
public SharedFormulaRecord linkSharedFormulaRecord(CellReference firstCell,
FormulaRecordAggregate agg)
- Parameters:
firstCell
- as extracted from the ExpPtg
from the cell's formula.
- Returns:
- never
null
getRecordForFirstCell
public SharedValueRecordBase getRecordForFirstCell(CellReference firstCell,
FormulaRecordAggregate agg)
- The
SharedValueRecordBase
record returned by this method
- Parameters:
firstCell
- the cell coordinates as read from the ExpPtg
or TblPtg
of the current formula. Note - this is usually not the same as the cell coordinates
of the formula's cell.
- Returns:
- the SHRFMLA, TABLE or ARRAY record for this formula cell, if it is the first cell of a
table or array region.
null
if
unlink
public void unlink(SharedFormulaRecord sharedFormulaRecord)
- Converts all
FormulaRecord
s handled by sharedFormulaRecord
to plain unshared formulas
