Enum StreamError.Condition

java.lang.Object
  java.lang.Enum<StreamError.Condition>
      org.xmpp.packet.StreamError.Condition

All Implemented Interfaces:

Serializable, Comparable<StreamError.Condition>

Enclosing class:

StreamError

public static enum StreamError.Condition
extends Enum<StreamError.Condition>

Type-safe enumeration for the error condition.

Implementation note: XMPP error conditions use "-" characters in their names such as "bad-request". Because "-" characters are not valid identifier parts in Java, they have been converted to "_" characters in the enumeration names, such as bad_request. The toXMPP() and fromXMPP(String) methods can be used to convert between the enumertation values and XMPP error code strings.

Enum Constant Summary

bad_format
The entity has sent XML that cannot be processed; this error MAY be used instead of the more specific XML-related errors, such as <bad-namespace-prefix/>, <invalid-xml/>, <restricted-xml/>, <unsupported-encoding/>, and <xml-not-well-formed/>, although the more specific errors are preferred.

bad_namespace_prefix
The entity has sent a namespace prefix that is unsupported, or has sent no namespace prefix on an element that requires such a prefix.

conflict
The server is closing the active stream for this entity because a new stream has been initiated that conflicts with the existing stream.

connection_timeout
The entity has not generated any traffic over the stream for some period of time (configurable according to a local service policy).

host_gone
The value of the 'to' attribute provided by the initiating entity in the stream header corresponds to a hostname that is no longer hosted by the server.

host_unknown
The value of the 'to' attribute provided by the initiating entity in the stream header does not correspond to a hostname that is hosted by the server.

improper_addressing
A stanza sent between two servers lacks a 'to' or 'from' attribute (or the attribute has no value).

internal_server_error
The server has experienced a misconfiguration or an otherwise-undefined internal error that prevents it from servicing the stream.

invalid_from
The JID or hostname provided in a 'from' address does not match an authorized JID or validated domain negotiated between servers via SASL or dialback, or between a client and a server via authentication and resource binding.

invalid_id
The stream ID or dialback ID is invalid or does not match an ID previously provided.

invalid_namespace
the streams namespace name is something other than "http://etherx.jabber.org/streams" or the dialback namespace name is something other than "jabber:server:dialback".

invalid_xml
The entity has sent invalid XML over the stream to a server that performs validation.

not_authorized
The entity has attempted to send data before the stream has been authenticated, or otherwise is not authorized to perform an action related to stream negotiation; the receiving entity MUST NOT process the offending stanza before sending the stream error.

policy_violation
The entity has violated some local service policy; the server MAY choose to specify the policy in the element or an application-specific condition element.

remote_connection_failed
The server is unable to properly connect to a remote entity that is required for authentication or authorization.

resource_constraint
The server lacks the system resources necessary to service the stream.

restricted_xml
The entity has attempted to send restricted XML features such as a comment, processing instruction, DTD, entity reference, or unescaped character.

see_other_host
The server will not provide service to the initiating entity but is redirecting traffic to another host; the server SHOULD specify the alternate hostname or IP address (which MUST be a valid domain identifier) as the XML character data of the <see-other-host/> element.

system_shutdown
The server is being shut down and all active streams are being closed.

undefined_condition
The error condition is not one of those defined by the other conditions in this list; this error condition SHOULD be used only in conjunction with an application-specific condition.

unsupported_encoding
The initiating entity has encoded the stream in an encoding that is not supported by the server.

unsupported_stanza_type
The initiating entity has sent a first-level child of the stream that is not supported by the server.

unsupported_version
the value of the 'version' attribute provided by the initiating entity in the stream header specifies a version of XMPP that is not supported by the server; the server MAY specify the version(s) it supports in the <text/> element.

xml_not_well_formed
The initiating entity has sent XML that is not well-formed.
