In POI, the HSSFFormulaEvaluator Evaluates every cell in each reference argument before calling the function. This means that functions using fixed references do not need access to the rest of the workbook to execute.

See OOO excelfileformat.pdf sec 4.18.2 'Sheet Protection in a Workbook (BIFF5-BIFF8)' @author Josh Micich Creates an empty WorksheetProtectionBlock @return true if the specified Record sid is one belonging to the 'Page Settings Block'. This method Reads {@link WorksheetProtectionBlock} records from the supplied RecordStream until the first non-WorksheetProtectionBlock record is encountered. As each record is Read, it is incorporated into this WorksheetProtectionBlock.

As per the OOO documentation, the protection block records can be expected to be written toGether (with no intervening records), but earlier versions of POI (prior to Jun 2009) didn't do this. Workbooks with sheet protection Created by those earlier POI versions seemed to be valid (Excel opens them OK). So PO allows continues to support Reading of files with non continuous worksheet protection blocks.

Note - when POI Writes out this WorksheetProtectionBlock, the records will always be written in one consolidated block (in the standard ordering) regardless of how scattered the records were when they were originally Read.

Description: Unicode String - just standard fields that are in several records. It is considered more desirable then repeating it in all of them.

This is often called a XLUnicodeRichExtendedString in MS documentation.

Most records construct themselves from {@link RecordInputStream}. This class assumes that a {@link ContinueRecord} record break always occurs at the type boundary, however, it is not always so.

{@link RecordInputStream} greedily requests the bytes to be read and stumbles on such files with a "Not enough data (1) to read requested (2) bytes" exception. The ContinuableRecordInput class circumvents this "type boundary" rule and Reads data byte-by-byte rolling over CONTINUE if necessary.

Some streams are usable After reaching EOF (typically those that return true for markSupported()). In the unlikely case that the caller has such a stream and needs to use it After this constructor completes, a work around is to wrap the stream in order to trap the close() call. A convenience method ( CreateNonClosingInputStream()) has been provided for this purpose:

             InputStream wrappedStream = POIFSFileSystem.CreateNonClosingInputStream(is);
             HSSFWorkbook wb = new HSSFWorkbook(wrappedStream);
             is.Reset();

             HSSFWorkbook wb = new HSSFWorkbook(bais); // calls bais.Close() !
             bais.Reset(); // no problem
             doSomethingElse(bais);
             

For a date, this is "mm/d/y". Objects of this class represent a single part of a cell format expression. Each cell can have up to four of these for positive, zero, negative, and text values.

Each format part can contain a color, a condition, and will always contain a format specification. For example "[Red][>=10]#" has a color ([Red]), a condition (>=10) and a format specification (#).

This class also Contains patterns for matching the subparts of format specification. These are used internally, but are made public in case other code has use for them. @author Ken Arnold, Industrious Media LLC Pattern for the color part of a cell format part.

For a date, this is "mm/d/y". Format a value according to the standard Excel behavior. This "standard" is not explicitly documented by Microsoft, so the behavior is determined by experimentation; see the tests. An Excel format has up to four parts, Separated by semicolons. Each part specifies what to do with particular kinds of values, depending on the number of parts given: - One part (example: [Green]#.##) If the value is a number, display according to this one part (example: green text, with up to two decimal points). If the value is text, display it as is. - Two parts (example: [Green]#.##;[Red]#.##) If the value is a positive number or zero, display according to the first part (example: green text, with up to two decimal points); if it is a negative number, display according to the second part (example: red text, with up to two decimal points). If the value is text, display it as is. - Three parts (example: [Green]#.##;[Black]#.##;[Red]#.##) If the value is a positive number, display according to the first part (example: green text, with up to two decimal points); if it is zero, display according to the second part (example: black text, with up to two decimal points); if it is a negative number, display according to the third part (example: red text, with up to two decimal points). If the value is text, display it as is. - Four parts (example: [Green]#.##;[Black]#.##;[Red]#.##;[@]) If the value is a positive number, display according to the first part (example: green text, with up to two decimal points); if it is zero, display according to the second part (example: black text, with up to two decimal points); if it is a negative number, display according to the third part (example: red text, with up to two decimal points). If the value is text, display according to the fourth part (example: text in the cell's usual color, with the text value surround by brackets). In Addition to these, there is a general format that is used when no format is specified. This formatting is presented by the {@link #GENERAL_FORMAT} object. @author Ken Arnold, Industrious Media LLC Maps a format string to its Parsed version for efficiencies sake. Returns a {@link CellFormat} that applies the given format. Two calls with the same format may or may not return the same object. @param format The format. @return A {@link CellFormat} that applies the given format. Creates a new object. @param format The format. Returns the result of Applying the format to the given value. If the value is a number (a type of {@link Number} object), the correct number format type is chosen; otherwise it is considered a text object. @param value The value @return The result, in a {@link CellFormatResult}. Returns the result of applying the format to the given date. @param date The date. @param numericValue The numeric value for the date. @return The result, in a {@link CellFormatResult}. Fetches the appropriate value from the cell, and returns the result of Applying it to the appropriate format. For formula cells, the computed value is what is used. @param c The cell. @return The result, in a {@link CellFormatResult}. Uses the result of Applying this format to the value, Setting the text and color of a label before returning the result. @param label The label to apply to. @param value The value to Process. @return The result, in a {@link CellFormatResult}.

• The 'ushort Length' field is assumed to have been explicitly written earlier. Hence, there may be an intervening {@link ContinueRecord}

• ushort Length
• byte optionFlags
• ushort numberOfRichTextRuns (optional)
• ushort extendedDataSize (optional)
• encoded character data (in "ISO-8859-1" or "UTF-16LE" encoding)

• The value of the 'is16bitEncoded' flag is determined by the actual character data of text
• The string header fields are never separated (by a {@link ContinueRecord}) from the first chunk of character data (i.e. the first character is always encoded in the same record as the string header).

This Is necessary due to the bizare way in which these records are Serialized. What happens Is that you Get a combination of MSODRAWING -> OBJ -> MSODRAWING -> OBJ records but the escher records are Serialized _across_ the MSODRAWING records. It Gets even worse when you start looking at TXO records. So what we do with this class Is aggregate lazily. That Is we don't aggregate the MSODRAWING -> OBJ records Unless we need to modify them. At first document contains 4 types of records which belong to drawing layer. There are can be such sequence of record:

DrawingRecord ContinueRecord ... ContinueRecord ObjRecord | TextObjectRecord ..... ContinueRecord ... ContinueRecord ObjRecord | TextObjectRecord NoteRecord ... NoteRecord

To work with shapes we have to read data from Drawing and Continue records into single array of bytes and build escher(office art) records tree from this array. Each shape in drawing layer matches corresponding ObjRecord Each textbox matches corresponding TextObjectRecord

ObjRecord contains information about shape. Thus each ObjRecord corresponds EscherContainerRecord(SPGR)

For POI internal use only @author Josh Micich @return null if there is no cell at the specified coordinates Only cells which have been split are Put in this map. (This has been done to conserve memory). Represents a workbook being used for forked Evaluation. Most operations are delegated to the shared master workbook, except those that potentially involve cell values that may have been updated After a call to {@link #getOrCreateUpdatableCell(String, int, int)}. @author Josh Micich Abstracts a workbook for the purpose of formula evaluation.

With standard formula Evaluation, around 90% of memory consumption is due to loading of the {@link HSSFWorkbook} or {@link NPOI.xssf.usermodel.XSSFWorkbook}. This class enables a 'master workbook' to be loaded just once and shared between many Evaluation clients. Each Evaluation client Creates its own {@link ForkedEvaluator} and can Set cell values that will be used for local Evaluations (and don't disturb Evaluations on other Evaluators). @author Josh Micich @deprecated (Sep 2009) (reduce overloading) use {@link #Create(Workbook, IStabilityClassifier, UDFFinder)} @param udfFinder pass null for default (AnalysisToolPak only) Sets the specified cell to the supplied value @param sheetName the name of the sheet Containing the cell @param rowIndex zero based @param columnIndex zero based Copies the values of all updated cells (modified by calls to {@link #updateCell(String, int, int, ValueEval)}) to the supplied workbook.
Typically, the supplied workbook is a writable copy of the 'master workbook', but at the very least it must contain sheets with the same names. If cell Contains a formula, the formula is Evaluated and returned, else the CellValue simply copies the appropriate cell value from the cell and also its cell type.
