Descrizione dei metodi

export

()

metodo

public static function export(textFlow:flashx.textLayout.elements:TextFlow):XML

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Exports a TextFlow into the markup language used by the Text Layout Framework, in the form of XML.

The root tag of the exported XML will be

      <TextFlow xmlns="http://ns.adobe.com/textLayout/2008" ...>

Parametri

textFlow:flashx.textLayout.elements:TextFlow — The TextFlow to be exported in Text Layout Framework markup language.

Restituisce

XML — XML containing Text Layout Framework markup language.

importFromString

()

metodo

 public static function importFromString(markup:String, whiteSpaceCollapse:String = "collapse"):flashx.textLayout.elements:TextFlow

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Creates a TextFlow by importing (i.e., parsing) a String containing the markup language used by the Text Layout Framework.

An example of a markup string is

      "<TextFlow xmlns='http://ns.adobe.com/textLayout/2008'>
      Hello, World!</TextFlow>"

However, you can use terser markup such as

"Hello, World!"

. It will get wrapped with a TextFlow tag in the proper namespace, and span and paragraph tags will get automatically inserted where needed to comply with the structure of a TextFlow.

If you specify the TextFlow tag yourself, it must be in the correct XML namespace for runtime Text Layout Framework markup, which is "http://ns.adobe.com/textLayout/2008".

Incorrect markup will cause this method to throw various exceptions. The error message will contain information about why it could not be parsed.

Parametri

	`markup:String` — The markup String to be imported.

	`whiteSpaceCollapse:String` (default = "`collapse`") — A String indicating whether the whitespace in the markup should be collapsed or preserved. The possible values are `WhiteSpaceCollapse.COLLAPSE` and `WhiteSpaceCollapse.PRESERVE` in the flashx.textLayout.formats.WhiteSpaceCollapse class. The default value is `WhiteSpaceCollapse.COLLAPSE`.

Restituisce

flashx.textLayout.elements:TextFlow — A new TextFlow instance created from the markup.

importFromXML

()

metodo

 public static function importFromXML(markup:XML, whiteSpaceCollapse:String = "collapse"):flashx.textLayout.elements:TextFlow

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4

Versioni runtime:

Flash Player 10, AIR 1.5

Creates a TextFlow by importing (parsing) XML that contains the markup language used by the Text Layout Framework.

An example of markup XML is

      <TextFlow xmlns='http://ns.adobe.com/textLayout/2008'>
        Hello, World!
      </TextFlow>

You can also use terser markup such as the following:

      "Hello, <span fontWeight='bold'>World!</span>"

The parser wraps the markup with a <TextFlow> tag in the proper namespace. The parser also inserts <span> and <paragraph> tags where needed to comply with the structure of a TextFlow object.

If you specify the TextFlow tag yourself, it must be in the correct XML namespace for runtime Text Layout Framework markup, which is "http://ns.adobe.com/textLayout/2008".

Incorrect markup causes this method to throw various exceptions. The error message contains information about why it could not be parsed.

Parametri

	`markup:XML` — The markup XML to be imported.

	`whiteSpaceCollapse:String` (default = "`collapse`") — A String indicating whether the whitespace in the markup should be collapsed or preserved. The possible values are `WhiteSpaceCollapse.COLLAPSE` and `WhiteSpaceCollapse.PRESERVE` in the flashx.textLayout.formats.WhiteSpaceCollapse class. The default value is `WhiteSpaceCollapse.COLLAPSE`.

Restituisce

flashx.textLayout.elements:TextFlow — A new TextFlow instance created from the markup.
