CSS::DOM::Exception - The Exception interface for CSS::DOM

  use CSS::DOM::Exception 'SYNTAX_ERR';
  eval {
          die new CSS::DOM::Exception
                  SYNTAX_ERR,
                  '1 is not a valid property declaration'
  };
  $@ == SYNTAX_ERR; # true
  print $@;    # prints "1 is not a valid property declaration\n";

This module implementations the W3C's DOMException interface. CSS::DOM::Exception objects stringify to the message passed to the constructer and numify to the error number (see below, under 'EXPORTS').

This class method creates a new exception object. $type is expected to be an integer (you can use the constants listed under 'EXPORTS'). $message is the error message.

The following constants are optionally exported. The descriptions are copied from the DOM spec.

If index or size is negative, or greater than the allowed value
If the specified range of text does not fit into a DOMString
If any node is inserted somewhere it doesn't belong
If a node is used in a different document than the one that created it (that doesn't support it)
If an invalid character is specified, such as in a name.
If data is specified for a node which does not support data
If an attempt is made to modify an object where modifications are not allowed
If an attempt was made to reference a node in a context where it does not exist
If the implementation does not support the type of object requested
If an attempt is made to add an attribute that is already inuse elsewhere
If an attempt is made to use an object that is not, or is no longer, usable
If an invalid or illegal string is specified
If an attempt is made to modify the type of the underlying object
If an attempt is made to create or change an object in a way which is incorrect with regard to namespaces
If a parameter or an operation is not supported by the underlying object
