Detailed Description

RWMimeContentTransferEncodingHeader represents the Content-Transfer-Encoding header of a MIME part. The Content-Transfer-Encoding header identifies whether the body of the part has been encoded and/or the character set of the body. A value of 7bit, 8bit, or binary indicates that the body has not been encoded, and the data is 7-bit US-ASCII, 8-bit US-ASCII, or binary, respectively. A value of base64 or quoted-printable indicates that the body has been encoded. Since both base64 encoding and quoted-printable encoding result in 7-bit US-ASCII encoded messages, either of these values also indicates that the body contains 7-bit US-ASCII data.

An instance of this class is a handle to a private, reference-counted body.

Reference

RWMimeContentTransferEncodingHeader conforms to the Content-Transfer-Encoding header requirements specified in RFC 2045, Section 6 (p. 14). For more details on encodings, see RFC 2045 or the discussion in the Internet Protocols Module User's Guide.

Constructor & Destructor Documentation

RWMimeContentTransferEncodingHeader::RWMimeContentTransferEncodingHeader

(

void

)

Default constructor. Constructs a header with the label "Content-Transfer-Encoding" and an empty value.

Note

A header with an empty value does not meet the requirements for a Content-Transfer-Encoding header.

RWMimeContentTransferEncodingHeader::RWMimeContentTransferEncodingHeader

(

const RWCString &

encoding

)

Constructs a header with the label "Content-Transfer-Encoding" and the value encoding. Does not validate encoding. The RWCString should contain 7-bit US-ASCII data.

RWMimeContentTransferEncodingHeader::RWMimeContentTransferEncodingHeader

(

const RWMimeContentTransferEncodingHeader &

second

)

Copy constructor. Constructs a new handle to the body second refers to.

RWMimeContentTransferEncodingHeader::RWMimeContentTransferEncodingHeader

(

const RWMimeHeader &

second

)

Conversion constructor. Constructs a new handle to the body second refers to. Throws RWMimeError if second does not have the label "Content-Transfer-Encoding".

virtual RWMimeContentTransferEncodingHeader::~RWMimeContentTransferEncodingHeader ( void  )

virtual

Destructor.

Member Function Documentation

RWMimeContentTransferEncodingHeaderImp& RWMimeContentTransferEncodingHeader::body ( void  ) const

protected

Returns a reference to the underlying implementation.

virtual bool RWMimeContentTransferEncodingHeader::checkLabel ( const RWCString &  label ) const

protectedvirtual

Returns true if label matches "Content-Transfer-Encoding", false otherwise. The comparison is case-insensitive. The RWCString should contain 7-bit US-ASCII data.

Reimplemented from RWMimeHeader.

RWCString RWMimeContentTransferEncodingHeader::getEncoding

(

void

)

const

Returns the encoding value of this header. The RWCString should contain 7-bit US-ASCII data.

RWMimeContentTransferEncodingHeader& RWMimeContentTransferEncodingHeader::operator=

(

const RWMimeContentTransferEncodingHeader &

second

)

Assignment operator. Makes self a handle identical to second.

void RWMimeContentTransferEncodingHeader::setEncoding

(

const RWCString &

encoding

)

Sets the encoding value of this header. Does not validate encoding. The RWCString should contain 7-bit US-ASCII data.

Member Data Documentation

const RWCString RWMimeContentTransferEncodingHeader::Label

static

Static constant string containing "Content-Transfer-Encoding", the label for a Content-Transfer-Encoding header. The RWCString should contain 7-bit US-ASCII data.
