ReportGenerator (net.sf.nervalreports:core 1.1 API)

java.lang.Object
- net.sf.nervalreports.core.ReportGenerator

```
public abstract class ReportGenerator
extends Object
```
Basic class for all generator's implementations.

A generator is a state machine of styles and commands, where each style affects all command calls after its definition (for those familiarized with fixed-pipelined OpenGL, it should be easy to get the general idea).

For example, when defined setBold(boolean) with true value, all texts added thereafter to the report will be rendered bold, until another call to setBold(boolean) is made with false value.

Also, each report element usually is added with sequential begin-end calls. For example, to add a table, one should call beginTable(int, int...), add any valid elements to it (with each specific command call) and then call endTable.

Although it's somewhat verbose, it's the best way to keep the creation easily portable to any kind of report format (html, tex, csv, ods) without any changes to the report code and, as much important, feasible to only iterate through the data once for most of the use cases (ideally, one should only iterate a single time through the report data. For example, when using a relational database, it should iterate to generate the report exactly at the same time it iterate through the ResultSet).

Page Footer and Header are defined with three elements: left, center and right, representing each one a corner of the page or its element center.

After a report is generated and no longer necessary, a call to release() is highly recommended.

To generator creators: All sanity validations to the state machine are made here with EmptyStackException and IllegalStateException.

The ReportGenerator class isn't thread-safe, but obviously each instance of a ReportGenerator should be (and in fact they are) independent, allowing the existence of multiple instances without interference between them.

                  throws ReportGenerationException
```
    Same of addTableCell(String), but defining its spans.
    
    Note: Must be inner a table row.
    
    Parameters:
    
    element - cell's text.
    
    colspan - number of columns occupied by the cell.

```
public void addTableCell(String element)

    Note: Must be inner a table row.
    
    Parameters:
    
    element - cell's text.
    
    Throws:
    
    ReportGenerationException

    Note: Should only be used inside page's headers or footers.

  - addImage
```
public void addImage(byte[] img,
                     String imgName,
                     int width)
              throws ReportGenerationException
```
    Add an image defined by a byte array of its format (usually it's safe to consider that all ReportGenerator's who support images will support PNG and JPG images formats here).
    
    Note: When using TeXReportGenerator, you must avoid using this function inside headers or footers.
    
    Parameters:
    
    img - image represented by a byte array.
    
    imgName - image name: must be unique per document and without spaces.
    
    width - width (in pixels) to display the image.
    
    Throws:
    
    ReportGenerationException
  - addLinkedImage
```
public void addLinkedImage(String imgLink,
                           int width)
                    throws ReportGenerationException
```
    Add an image to the document by its link. If the link is for a jar or URL and supportImagesOfJarFilesOrURLs() is false, it's recommended to insert it - if not at header or footer - via addImage(byte[], String, int), or to extract it to a file and insert via the path as link.
    
    Parameters:
    
    imgLink - path to the image.
    
    width - width (in pixels) to display the image.
    
    Throws:
    
    ReportGenerationException
  - addLineSpaces
```
public void addLineSpaces(int n)
                   throws ReportGenerationException
```
    Add n blank lines to the report.
    
    Parameters:
    
    n - Number of blank lines to add.
    
    Throws:
    
    ReportGenerationException
  - addLineBreak
```
public void addLineBreak()
                  throws ReportGenerationException
```
    Add a line break to the document. Not all documents support line breaks inner tables, so use with parsimony.
    Note: Current font size will affect the height (and so line space) of the line break.
    
    Throws:
    
    ReportGenerationException
  - addTextWithNullSupport
```
public void addTextWithNullSupport(String text)
                            throws ReportGenerationException
```
    Add (or better, append) a contiguous text to the report, replacing null and empty values with '-'.
    
    Parameters:
    
    text - String with the text to append or null.
    
    Throws:
    
    ReportGenerationException
  - addText
```
public void addText(String text)
             throws ReportGenerationException
```
    Add (or better, append) a contiguous text to the report.
    
    Note: The text should not be empty. For potential empty texts, use addTextWithNullSupport(String).
    
    Parameters:
    
    text - String with the text to append.
    
    Throws:
    
    ReportGenerationException
  - addTextLine
```
public void addTextLine(String line)
                 throws ReportGenerationException
```
    Add text to the report with a line break at end.
    
    Parameters:
    
    line - String with text to add.
    
    Throws:
    
    ReportGenerationException
  - addSeparatorLine
```
public void addSeparatorLine()
                      throws ReportGenerationException
```
    Add an horizontal line (-----) separator to the report.
    
    Throws:
    
    ReportGenerationException
  - checkDocumentNotFinished
```
protected void checkDocumentNotFinished()
```
    Check if document is inited and not yet finished.
  - checkNotOpenedFooterOrHeader
```
protected void checkNotOpenedFooterOrHeader()
```
    Check if no footer or header block is currently opened.
    
    Throws:
    
    IllegalStateException - if the top isn't one of those expected or null.
  - checkStackState
```
protected void checkStackState(boolean pop,
                               net.sf.nervalreports.core.ReportGenerator.ReportBlockToken... expected)
```
    Verify the top of currently opened commands, expecting at last one type.
    
    Parameters:
    
    pop - if will pop (true) or peek (false) the stack top to check.
    
    expected - valid expected types.
    
    Throws:
    
    IllegalStateException - if the top isn't one of those expected or null.
    
    EmptyStackException - if the command stack is empty.
