## Detailed Description

The fundamental unit of text within an output file containing code.

## Constructor & Destructor Documentation

## ◆ TextBlock()

TextBlock::TextBlock | ( | CodeDocument * | parent,
|  | const QString & | text = `QString()`
| ) |  |

explicit

Constructor.

## ◆ ~TextBlock()

TextBlock::~TextBlock | ( |  | ) |

virtual

Destructor.

## Member Function Documentation

## ◆ appendText()

void TextBlock::appendText | ( | const QString & | text | ) |

Add text to this object.

Parameters

  text | the text to add

## ◆ canDelete()

bool TextBlock::canDelete | ( |  | ) | const

Determine if its OK to delete this textblock from the document. Used by the text editor to know if deletion could cause a crash of the program.

Returns
  the value of m_canDelete

## ◆ decodeText()

QString TextBlock::decodeText | ( | const QString & | text,
|  | const QString & | endLine
| ) |  |

static

Decode text from XML storage. We simply convert all newLine entity &#010; to chosen line ending.

Parameters

  text | the not yet decoded text
  endLine | the chars at the end of each line

Returns
  the decoded text

## ◆ encodeText()

QString TextBlock::encodeText | ( | const QString & | text,
|  | const QString & | endLine
| ) |  |

static

Encode text for XML storage. We simply convert all types of newLines to the "\n" or &#010; entity.

Parameters

  text | the not yet encoded text
  endLine | the chars at the end of each line

Returns
  the encoded text

## ◆ firstEditableLine()

int TextBlock::firstEditableLine | ( |  | ) |

virtual

TODO: Ush. These are terrifically bad and must one day go away. Both methods indicate the range of lines in this textblock which may be edited by the codeeditor (assuming that any are actually editable). The default case is no lines are editable. The line numbering starts with '0' and a '-1' means no line qualifies.

Returns
  line number

Reimplemented in CPPCodeDocumentation, DCodeDocumentation, JavaCodeDocumentation, and RubyCodeDocumentation.

## ◆ formatMultiLineText()

QString TextBlock::formatMultiLineText | ( | const QString & | work,
|  | const QString & | linePrefix,
|  | const QString & | breakStr,
|  | bool | addBreak = `true`,
|  | bool | lastLineHasBreak = `true`
| ) |  |

static

Format a long text string to be more readable.

Parameters

  work | the original text for formatting
  linePrefix | a line prefix
  breakStr | a break string
  addBreak | control to add always a break string
  lastLineHasBreak | control to add a break string to the last line

Returns
  the new formatted text

## ◆ getIndentation()

QString TextBlock::getIndentation | ( |  | ) |

static

Get how much a single "level" of indentation will actually indent.

Returns
  the unit of indentation (for one level)

## ◆ getIndentationLevel()

int TextBlock::getIndentationLevel | ( |  | ) | const

Get how many times to indent this text block. The amount of each indentation is determined from the parent codedocument codegeneration policy.

Returns
  the indentation level

## ◆ getIndentationString()

QString TextBlock::getIndentationString | ( | int | level = `0` | ) | const

Get the actual amount of indentation for a given level of indentation.

Parameters

  level | the level of interest

Returns
  the indentation string

## ◆ getNewEditorLine()

QString TextBlock::getNewEditorLine | ( | int | amount = `0` | ) |

virtual

Used by the CodeEditor. It provides it with an appropriate starting string for a new line of text within the given textblock (for example a string with the proper indentation). If the indentation amount is '0' the current indentation string will be used.

TODO: Can be refactored away and replaced with getIndentationString.

Parameters

  amount | the number of indent steps to use

Returns
  the new line

Reimplemented in CPPCodeComment, CPPCodeDocumentation, DCodeComment, DCodeDocumentation, JavaCodeComment, JavaCodeDocumentation, RubyCodeComment, and RubyCodeDocumentation.

Returns
  the ending chars for new line

  the value of m_parentDoc

## ◆ getTag()

QString TextBlock::getTag | ( |  | ) | const

Get the tag of this text block. This tag may be used to find this text block in the code document to which it belongs.

Returns
  the tag

## ◆ getText()

QString TextBlock::getText | ( |  | ) | const

Get the value of m_text The actual text of this code block.

Returns
  the value of m_text

## ◆ getWriteOutText()

bool TextBlock::getWriteOutText | ( |  | ) | const

Get the value of m_writeOutText Whether or not to include the text of this TextBlock into a file.
