Class SafeStylesBuilder

    java.lang.Object
      com.google.gwt.safecss.shared.SafeStylesBuilder

    public final class SafeStylesBuilder

extends java.lang.Object

A builder that facilitates the building up of XSS-safe CSS attribute strings from `SafeStyles`. It is used essentially like a `StringBuilder`, but access `SafeStyles` instead of Strings.

Constructor Detail

### SafeStylesBuilder

    public SafeStylesBuilder()

  Constructs an empty `SafeStylesBuilder`.

Method Detail

### append

    public SafeStylesBuilder append(SafeStyles styles)

  Appends the contents of another `SafeStyles` object, without applying any escaping or sanitization to it.

  Parameters:
    `styles` - the `SafeStyles` to append
  Returns:
    a reference to this object

### appendTrustedString

    public SafeStylesBuilder appendTrustedString(java.lang.String styles)

  Appends `SafeStyles` constructed from a trusted string, i.e., without escaping the string. Only minimal checks are performed. The calling code should be carefully reviewed to ensure the argument meets the `SafeStyles` contract.

  Generally, `SafeStyles` should be of the form `cssPropertyName:value;`, where neither the name nor the value contain malicious scripts.

  `SafeStyles` may never contain literal angle brackets. Otherwise, it could be unsafe to place a `SafeStyles` into a <style> tag (where it can't be HTML escaped). For example, if the `SafeStyles` containing " `font: 'foo <style><script>evil</script>`'" is used in a style sheet in a <style> tag, this could then break out of the style context into HTML.

  The following example values comply with this type's contract:

  - `width: 1em;`
  - `height:1em;`
  - `width: 1em;height: 1em;`
  - `background:url('http://url');`
  In addition, the empty string is safe for use in a CSS attribute.

  The following example values do not comply with this type's contract:

  - `background: red` (missing a trailing semi-colon)
  - `background:` (missing a value and a trailing semi-colon)
  - `1em` (missing an attribute name, which provides context for the value)

  Parameters:
    `styles` - the input String
  Returns:
    a `SafeStyles` instance

### backgroundImage

    public SafeStylesBuilder backgroundImage(SafeUri uri)
