DOM operations only raise exceptions in "exceptional" circumstances, i.e.,
when an operation is impossible to perform (either for logical reasons,
because data is lost, or because the implementation has become unstable).
In general, DOM methods return specific error values in ordinary
processing situations, such as out-of-bound errors when using
.
Implementations should raise other exceptions under other circumstances.
For example, implementations should raise an implementation-dependent
exception if a null
argument is passed when null
was not expected.
Some languages and object systems do not support the concept of
exceptions. For such systems, error conditions may be indicated using
native error reporting mechanisms. For some bindings, for example,
methods may return error codes similar to those listed in the
corresponding method descriptions.
Field Summary |
---|
public short | code | |
public static final short | INDEX_SIZE_ERR | If index or size is negative, or greater than the allowed value. |
public static final short | DOMSTRING_SIZE_ERR | If the specified range of text does not fit into a
DOMString . |
public static final short | HIERARCHY_REQUEST_ERR | If any Node is inserted somewhere it doesn't belong. |
public static final short | WRONG_DOCUMENT_ERR | If a Node is used in a different document than the one
that created it (that doesn't support it). |
public static final short | INVALID_CHARACTER_ERR | If an invalid or illegal character is specified, such as in an XML name. |
public static final short | NO_DATA_ALLOWED_ERR | If data is specified for a Node which does not support
data. |
public static final short | NO_MODIFICATION_ALLOWED_ERR | If an attempt is made to modify an object where modifications are not
allowed. |
public static final short | NOT_FOUND_ERR | If an attempt is made to reference a Node in a context
where it does not exist. |
public static final short | NOT_SUPPORTED_ERR | If the implementation does not support the requested type of object or
operation. |
public static final short | INUSE_ATTRIBUTE_ERR | If an attempt is made to add an attribute that is already in use
elsewhere. |
public static final short | INVALID_STATE_ERR | If an attempt is made to use an object that is not, or is no longer,
usable. |
public static final short | SYNTAX_ERR | If an invalid or illegal string is specified. |
public static final short | INVALID_MODIFICATION_ERR | If an attempt is made to modify the type of the underlying object. |
public static final short | NAMESPACE_ERR | If an attempt is made to create or change an object in a way which is
incorrect with regard to namespaces. |
public static final short | INVALID_ACCESS_ERR | If a parameter or an operation is not supported by the underlying
object. |
public static final short | VALIDATION_ERR | If a call to a method such as insertBefore or
removeChild would make the Node invalid
with respect to "partial validity", this exception would be raised
and the operation would not be done. This code is used in [DOM Level 3 Validation]
. Refer to this specification for further information. |
public static final short | TYPE_MISMATCH_ERR | If the type of an object is incompatible with the expected type of the
parameter associated to the object. |
static final long | serialVersionUID | |
