Constant Field Values

ExternSheetRecord

public ExternSheetRecord()

ExternSheetRecord

public ExternSheetRecord(RecordInputStream in)

getNumOfRefs

public int getNumOfRefs()

Returns:

number of REF structures

addREFRecord

public void addREFRecord(org.apache.poi.hssf.record.ExternSheetRecord.RefSubRecord rec)

adds REF struct (ExternSheetSubRecord)

Parameters:

rec - REF struct

getNumOfREFRecords

public int getNumOfREFRecords()

returns the number of REF Records, which is in model

Returns:

number of REF records

toString

public java.lang.String toString()

Description copied from class: Record

get a string representation of the record (for biffview/debugging)

Overrides:

toString in class Record

getDataSize

protected int getDataSize()

Specified by:

getDataSize in class StandardRecord

serialize

public void serialize(LittleEndianOutput out)

Description copied from class: StandardRecord

Write the data content of this BIFF record. The 'ushort sid' and 'ushort size' header fields have already been written by the superclass.

The number of bytes written must equal the record size reported by RecordBase.getRecordSize()} minus four ( record header consisting of a 'ushort sid' and 'ushort reclength' has already been written by their superclass).

Specified by:

serialize in class StandardRecord

Parameters:

out - the output object

removeSheet

public void removeSheet(int sheetIdx)

getSid

public short getSid()

return the non static version of the id for this record.

Specified by:

getSid in class Record

Returns:

he id for this record

getExtbookIndexFromRefIndex

public int getExtbookIndexFromRefIndex(int refIndex)

Parameters:

refIndex - specifies the n-th refIndex

Returns:

the index of the SupBookRecord for this index

findRefIndexFromExtBookIndex

public int findRefIndexFromExtBookIndex(int extBookIndex)

Parameters:

extBookIndex - external sheet reference index

Returns:

-1 if not found

getFirstSheetIndexFromRefIndex

public int getFirstSheetIndexFromRefIndex(int extRefIndex)

Returns the first sheet that the reference applies to, or -1 if the referenced sheet can't be found, or -2 if the reference is workbook scoped.

Parameters:

extRefIndex - external sheet reference index

Returns:

the first sheet that the reference applies to, or -1 if the referenced sheet can't be found, or -2 if the reference is workbook scoped

getLastSheetIndexFromRefIndex

public int getLastSheetIndexFromRefIndex(int extRefIndex)

Returns the last sheet that the reference applies to, or -1 if the referenced sheet can't be found, or -2 if the reference is workbook scoped. For a single sheet reference, the first and last should be the same.

Parameters:

extRefIndex - external sheet reference index

Returns:

the last sheet that the reference applies to, or -1 if the referenced sheet can't be found, or -2 if the reference is workbook scoped.

addRef

public int addRef(int extBookIndex,
                  int firstSheetIndex,
                  int lastSheetIndex)

Add a zero-based reference to a SupBookRecord.

If the type of the SupBook record is same-sheet referencing, Add-In referencing, DDE data source referencing, or OLE data source referencing, then no scope is specified and this value MUST be -2. Otherwise, the scope must be set as follows:

1. -2 Workbook-level reference that applies to the entire workbook.
2. -1 Sheet-level reference.
3. >=0 Sheet-level reference. This specifies the first sheet in the reference.

   If the SupBook type is unused or external workbook referencing, then this value specifies the zero-based index of an external sheet name, see SupBookRecord.getSheetNames(). This referenced string specifies the name of the first sheet within the external workbook that is in scope. This sheet MUST be a worksheet or macro sheet.

   If the supporting link type is self-referencing, then this value specifies the zero-based index of a BoundSheetRecord record in the workbook stream that specifies the first sheet within the scope of this reference. This sheet MUST be a worksheet or a macro sheet.

Parameters:

extBookIndex - the external book block index

firstSheetIndex - the scope, must be -2 for add-in references

lastSheetIndex - the scope, must be -2 for add-in references

Returns:

index of newly added ref

getRefIxForSheet

public int getRefIxForSheet(int externalBookIndex,
                            int firstSheetIndex,
                            int lastSheetIndex)

combine
