Method Detail

getSheets

public abstract WritableSheet[] getSheets()
Gets the sheets within this workbook. Use of this method for large worksheets can cause performance problems.

Returns:
an array of the individual sheets

public abstract java.lang.String[] getSheetNames()
Gets the sheet names

Returns:
an array of strings containing the sheet names

index - the zero based index of the reQuired sheet
Returns:
The sheet specified by the index

public abstract WritableSheet getSheet(java.lang.String name)
Gets the sheet with the specified name from within this workbook

Parameters:
name - the sheet name
Returns:
The sheet with the specified name, or null if it is not found

getWritableCell

public abstract WritableCell getWritableCell(java.lang.String loc)
Returns the cell for the specified location eg. "Sheet1!A4". This is identical to using the CellReferenceHelper with its associated performance overheads, consequently it should be use sparingly

loc - the cell to retrieve
Returns:
the cell at the specified location
