HttpHeaders

Maintains a set of output headers. These are held in an output buffer, and indexed via a HttpStack. Deleting a header could be supported by setting the HttpStack entry to null, and ignoring such values when it's time to write the headers.

class HttpHeaders : HttpHeadersView {

this();

this(HttpHeaders source);

HttpHeaders clone();

void add(HttpHeaderName name, void delegate(OutputBuffer) dg);

void add(HttpHeaderName name, cstring value);

void addInt(HttpHeaderName name, int value);

void addDate(HttpHeaderName name, Time value);

bool remove(HttpHeaderName name);

}

Constructors

this this(): Construct output headers
this this(HttpHeaders source): Clone a source set of HttpHeaders

Functions

add void add(HttpHeaderName name, void delegate(OutputBuffer) dg): Add the specified header, and use a callback to provide the content.
add void add(HttpHeaderName name, cstring value): Add the specified header and text
addDate void addDate(HttpHeaderName name, Time value): Add the specified header and long/date value
addInt void addInt(HttpHeaderName name, int value): Add the specified header and integer value
clone HttpHeaders clone(): Clone this set of HttpHeaders
remove bool remove(HttpHeaderName name): Remove the specified header header. Returns false if not found.

Inherited Members

From HttpHeadersView

parse alias parse = HttpTokens.parse: Undocumented in source.
clone HttpHeadersView clone(): Clone this set of HttpHeadersView
retain HttpHeadersView retain(bool yes): Control whether headers are duplicated or not. Default behaviour is aliasing instead of copying, avoiding any allocation overhead. However, the default won't preserve those headers once additional content has been read.
parse void parse(InputBuffer input): Read all header lines. Everything is mapped rather than being allocated & copied
get cstring get(HttpHeaderName name, cstring def): Return the value of the provided header, or null if the header does not exist
getInt int getInt(HttpHeaderName name, int def): Return the integer value of the provided header, or -1 if the header does not exist
getDate Time getDate(HttpHeaderName name, Time def): Return the date value of the provided header, or Time.epoch if the header does not exist
opApply int opApply(int delegate(ref HeaderElement) dg): Iterate over the set of headers. This is a shell around the superclass, where we can convert the HttpToken into a HeaderElement instead.
createFilter FilteredHeaders createFilter(HttpHeaderName header): Create a filter for iterating of a set of named headers. We have to create a filter since we can't pass additional arguments directly to an opApply() method.
