Refer to the documentation for details. This policy adds new header parsing and folding algorithms. Instead of simple strings, headers are custom objects with custom attributes depending on the type of the field. The folding algorithm fully implements RFCs 2047 and 5322. In addition to the settable attributes listed above that apply to all Policies, this policy adds the following additional attributes: refold_source -- if the value for a header in the Message object came from the parsing of some source, this attribute indicates whether or not a generator should refold that value when transforming the message back into stream form. The possible values are: none -- all source values use original folding long -- source values that have any line that is longer than max_line_length will be refolded all -- all values are refolded. The default is 'long'. header_factory -- a callable that takes two arguments, 'name' and 'value', where 'name' is a header field name and 'value' is an unfolded header field value, and returns a string-like object that represents that header. A default header_factory is provided that understands some of the RFC5322 header field types. (Currently address fields and date fields have special treatment, while all other fields are treated as unstructured. This list will be completed before the extension is marked stable.) u longc s9 d | k r% t j | d t � � n t � j | � d S( Nu header_factory( u objectu __setattr__u HeaderRegistryu superu __init__( u selfu kw( u __class__( u1 /opt/alt/python33/lib64/python3.3/email/policy.pyu __init__B s u EmailPolicy.__init__c C s | j | j S( u� + The implementation for this class returns the max_count attribute from the specialized header class that would be used to construct a header of type 'name'.

A value is considered to be a 'source value' if and only if it does not have a 'name' attribute (having a 'name' attribute means it is a header object of some sort). If a source value needs to be refolded according to the policy, it is converted into a custom header object by passing the name and the value with any linesep characters removed to the header_factory method. Folding of a custom header object is done by calling its fold method with the current policy. Source values are split into lines using splitlines. If the value is not to be refolded, the lines are rejoined using the linesep from the policy and returned. The exception is lines containing non-ascii binary data. In that case the value is refolded regardless of the refold_source setting, which causes the binary data to be CTE encoded using the unknown-8bit charset. u refold_binaryT( u _foldu True( u selfu nameu value( ( u1 /opt/alt/python33/lib64/python3.3/email/policy.pyu fold� s u EmailPolicy.foldc C s1 | j | | d | j d k �} | j d d � S( u� + The same as fold if cte_type is 7bit, except that the returned value is bytes.
