Detailed Description

RWHttpContentTypeHeader is a specialization class of RWHttpHeaderBase. It is a helper class that formats its contents as Content-Type: header_value, where header_value is the media type and sub type of the message, as well as any parameters describing the content.

Examples

 RWHttpContentTypeHeader hdr("text", "plain");
 hdr.addParameter("charset", "iso-2022-jp");

Constructor & Destructor Documentation

RWHttpContentTypeHeader::RWHttpContentTypeHeader

(

void

)

[inline]

Constructs a default RWHttpContentTypeHeader object with the label Content-Type and the value text/plain.

RWHttpContentTypeHeader::RWHttpContentTypeHeader	(	const RWCString &	mediaType,
		const RWCString &	subType
	)

Constructs an RWHttpContentTypeHeader with the label ContentType and the value mediaType / subType.

RWHttpContentTypeHeader::RWHttpContentTypeHeader

(

const RWHttpGenericHeader &

hdr

)

Constructs an RWHttpContentTypeHeader object from an RWHttpGenericHeader that represents a Content-Type header. If the RWHttpGenericHeader does not represent a Content-Type header or if the value of the RWHttpGenericHeader does not conform to the formatting of a Content-Type value, an RWHttpHeaderParseError exception is thrown.

const [virtual]

Returns the value of this header as an RWCString. This includes the media and sub types, as well as any parameters associated with the header, formatted according the HTTP specification's requirements.

Implements RWHttpHeaderBase.

bool RWHttpContentTypeHeader::removeParameter

(

const RWCString &

name

)
