Package mms :: Module wsp_pdu :: Class WSPEncodingAssignments

Class WSPEncodingAssignments

Static class containing the constant values defined in [5] for well-known content types, parameter names, etc.

It also defines some function for combining assigned number-tables for specific WSP encoding versions, where appropriate.

This is used by both the Encoder and Decoder classes during well-known assigned number lookups (usually these functions have the string WellKnown in their names).

Assigned parameters are stored in a dictionary, wkParameters, containing all assigned values for WSP encoding versions 1.1 - 1.4, in the format: {<int>assigned number: (<str>name, <str>expected value type)} A "encoding versioned"-version of this dictionary can be retrieved by calling the wellKnowParameters() function with an appropriate WSP encoding version as parameter.
Assigned content types are stored in a list, wkContentTypes, in order; thus, their index in the list is equal to their assigned value.

wellKnownParameters(encodingVersion=`'1.2'`)
Static Method

source code

Formats list of assigned values for well-known parameter names, for the specified WSP encoding version.

Parameters:

encodingVersion (str) - The WSP encoding version to use. This defaults to "1.2", but may be "1.1", "1.2", "1.3" or "1.4" (see table 38 in [5] for details).

Returns: dict

A dictionary containing the well-known parameters with assigned numbers for the specified encoding version (and lower). Entries in this dict follow the format:

{<int:assigned_number> : (<str:param_name>, 
          <str:expected_type>)}

Raises:

ValueError - The specified encoding version is invalid.

headerFieldNames(encodingVersion=`'1.2'`)
Static Method

source code

Formats list of assigned values for header field names, for the specified WSP encoding version.

Parameters:

encodingVersion (str) - The WSP encoding version to use. This defaults to "1.2", but may be "1.1", "1.2", "1.3" or "1.4" (see table 39 in [5] for details).

Returns: list

A list containing the WSP header field names with assigned numbers for the specified encoding version (and lower).

Raises:

ValueError - The specified encoding version is invalid.
