public class DOMException extends RuntimeException

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 NodeList.

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.

Constant Summary

short DOMSTRING_SIZE_ERR If the specified range of text does not fit into a DOMString.
short HIERARCHY_REQUEST_ERR If any Node is inserted somewhere it doesn't belong.
short INDEX_SIZE_ERR If index or size is negative, or greater than the allowed value.
short INUSE_ATTRIBUTE_ERR If an attempt is made to add an attribute that is already in use elsewhere.
short INVALID_ACCESS_ERR If a parameter or an operation is not supported by the underlying object.
short INVALID_CHARACTER_ERR If an invalid or illegal character is specified, such as in an XML name.
short INVALID_MODIFICATION_ERR If an attempt is made to modify the type of the underlying object.
short INVALID_STATE_ERR If an attempt is made to use an object that is not, or is no longer, usable.
short NAMESPACE_ERR If an attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
short NOT_FOUND_ERR If an attempt is made to reference a Node in a context where it does not exist.
short NOT_SUPPORTED_ERR If the implementation does not support the requested type of object or operation.
short NO_DATA_ALLOWED_ERR If data is specified for a Node which does not support data.
short NO_MODIFICATION_ALLOWED_ERR If an attempt is made to modify an object where modifications are not allowed.
short SYNTAX_ERR If an invalid or illegal string is specified.
short TYPE_MISMATCH_ERR If the type of an object is incompatible with the expected type of the parameter associated to the object.
