## Interface MarkupModel

- All Known Implementing Classes:
    `AbstractMarkupModel`, `DefaultMarkupModel`, `Html5MarkupModel`, `XMLMarkupModel`

      public interface MarkupModel

  Used by a the DOM to determine how to produce markup. Delegates details about converted entities and some formatting details. This exists to handle the differences between traditional HTML output (which is SGML based, meaning there can be elements that are valid without a close tag) and "modern" XML, such as XHTML. Generally speaking, for XHTML it is vital that a !DOCTYPE be included in the rendered response, or the browser will be unable to display the result properly.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method | Description
    --- | --- | ---
    `String` | `encode​(String content)` | Encodes the characters, converting control characters (such as '<') into corresponding entities (such as &lt;).
    `void` | `encodeQuoted​(String content, StringBuilder buffer)` | Encodes the characters into the buffer for use in a quoted value (that is, an attribute value), converting control characters (such as '<') into corresponding entities (such as &lt;).
    `char` | `getAttributeQuote()` | What character is used when generating quotes around attribute values? This will be either a single or double quote.
    `EndTagStyle` | `getEndTagStyle​(String element)` | For a given element, determines how the end tag for the element should be rendered.
    `boolean` | `isXML()` | Returns true if the document markup is XML, which is used to determine the need for an XML declaration at the start of the document, and whether CDATA sections are supported.

    - #### encode

          String encode​(String content)

      Returns:
        the filtered content

    - #### encodeQuoted

          void encodeQuoted​(String content,
                            StringBuilder buffer)

      Encodes the characters into the buffer for use in a quoted value (that is, an attribute value), converting control characters (such as '<') into corresponding entities (such as &lt;). In addition, double quotes must be quoted or otherwise escaped.
      Parameters:
        `content` - to be filtered
        `buffer` - to receive the filtered content

    - #### getEndTagStyle

          EndTagStyle getEndTagStyle​(String element)

      For a given element, determines how the end tag for the element should be rendered.

    - #### isXML

          boolean isXML()

      Returns true if the document markup is XML, which is used to determine the need for an XML declaration at the start of the document, and whether CDATA sections are supported.
      Returns:
        true for XML output, false for HTML output

    - #### getAttributeQuote

          char getAttributeQuote()

      What character is used when generating quotes around attribute values? This will be either a single or double quote.
      Returns:
        single (') or double (") quote
