                     CSSCharsetRule

The CSSCharsetRule interface represents an @charset rule in a CSS style sheet. The value of the encoding attribute does not affect the encoding of text data in the DOM objects; this encoding is always UTF-16 (also in Python?). After a stylesheet is loaded, the value of the encoding attribute is the value found in the @charset rule. If there was no @charset in the original document, then no CSSCharsetRule is created. The value of the encoding attribute may also be used as a hint for the encoding used on serialization of the style sheet.

The value of the @charset rule (and therefore of the CSSCharsetRule) may not correspond to the encoding the document actually came in; character encoding information e.g. in an HTTP header, has priority (see CSS document representation) but this is not reflected in the CSSCharsetRule.

# Properties

cssText: of type DOMString
  The parsable textual representation of this rule
encoding: of type DOMString
  The encoding information used in this @charset rule.

Inherits properties from CSSRule

# Format

charsetrule:
  CHARSET_SYM S* STRING S* ';'
BUT: Only valid format is:
  @charset "ENCODING";

Method Details | [hide private]

### __init__(self, encoding=None, readonly=False) (Constructor) | source code
encoding: a valid character encoding readonly: defaults to False, not used yet if readonly allows setting of properties in constructor only Overrides: cssrule.CSSRule.__init__

### _setEncoding(self, encoding) | source code
DOMException on setting NO_MODIFICATION_ALLOWED_ERR: (CSSRule) Raised if this encoding rule is readonly. SYNTAX_ERR: (self) Raised if the specified encoding value has a syntax error and is unparsable. Currently only valid Python encodings are allowed.

### _getCssText(self) | source code
returns serialized property cssText Overrides: cssrule.CSSRule._getCssText

### _setCssText(self, cssText) | source code
DOMException on setting SYNTAX_ERR: (self) Raised if the specified CSS string value has a syntax error and is unparsable. INVALID_MODIFICATION_ERR: (self) Raised if the specified CSS string value represents a different type of rule than the current one. HIERARCHY_REQUEST_ERR: (CSSStylesheet) Raised if the rule cannot be inserted at this point in the style sheet. NO_MODIFICATION_ALLOWED_ERR: (CSSRule) Raised if the rule is readonly. Overrides: cssrule.CSSRule._setCssText

### __repr__(self) (Representation operator) | source code
repr(x) Overrides: object.__repr__ (inherited documentation)

### __str__(self) (Informal representation operator) | source code
str(x) Overrides: object.__str__ (inherited documentation)
