HTML::DOM::Exception - The Exception interface for HTML::DOM
use HTML::DOM::Exception 'INVALID_CHARACTER_ERR';
eval {
die new HTML::DOM::Exception
INVALID_CHARACTER_ERR,
'Only ASCII characters allowed!'
};
$@ == INVALID_CHARACTER_ERR; # true
print $@; # prints "Only ASCII characters allowed!\n";
This module implementations the W3C's DOMException and EventException
interfaces. HTML::DOM::Exception objects stringify to the message passed to
the constructer and numify to the error number (see below, under 'EXPORTS').
- $errr = new HTML::DOM::Exception $type, $message
- 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.
- $errr->code
- Returns the error code. Same as
"0+$errr".
The following constants are optionally exported. The descriptions are copied
from the DOM spec.
- INDEX_SIZE_ERR (1)
- If index or size is negative, or greater than the allowed value
- DOMSTRING_SIZE_ERR (2)
- If the specified range of text does not fit into a DOMString
- HIERARCHY_REQUEST_ERR (3)
- If any node is inserted somewhere it doesn't belong
- WRONG_DOCUMENT_ERR (4)
- If a node is used in a different document than the one that created it
(that doesn't support it)
- INVALID_CHARACTER_ERR (5)
- If an invalid character is specified, such as in a name.
- NO_DATA_ALLOWED_ERR (6)
- If data is specified for a node which does not support data
- NO_MODIFICATION_ALLOWED_ERR (7)
- If an attempt is made to modify an object where modifications are not
allowed
- NOT_FOUND_ERR (8)
- If an attempt was made to reference a node in a context where it does not
exist
- NOT_SUPPORTED_ERR (9)
- If the implementation does not support the type of object requested
- INUSE_ATTRIBUTE_ERR (10)
- If an attempt is made to add an attribute that is already inuse
elsewhere
- INVALID_STATE_ERR (11)
- If an attempt is made to use an object that is not, or is no longer,
usable
- SYNTAX_ERR (12)
- If an invalid or illegal string is specified
- INVALID_MODIFICATION_ERR (13)
- If an attempt is made to modify the type of the underlying object
- NAMESPACE_ERR (14)
- If an attempt is made to create or change an object in a way which is
incorrect with regard to namespaces
- INVALID_ACCESS_ERR (15)
- If a parameter or an operation is not supported by the underlying
object
- UNSPECIFIED_EVENT_TYPE_ERR (0)
- If the Event's type was not specified by initializing the event before the
method was called. Specification of the Event's type as null or an empty
string will also trigger this exception.
Hey! The above document had some coding errors, which are explained
below:
- Around line 117:
- You forgot a '=back' before '=head1'
